+\chapter{入门}
+
+\section{Hello, World!}
+\label{sec:hello_world}
+把下面例子用编辑器保存为~\verb|hello_world.tex|,这就是一个最简单的~\LaTeX~源文件。
+
+\begin{code}
+%hello_world.tex
+\documentclass{article}
+\begin{document}
+ Hello, World!
+\end{document}
+\end{code}
+
+有了源文件,我们可以在命令行把它编译成~DVI~文件(DVI~格式见\ref{sec:dvi}小节)。此命令知道输入的是~\LaTeX~源文件,所以这里的~\verb|.tex|~后缀可以省略。以后的示例中可以省略的后缀都用~\verb|()|~标出,不再特别声明。
+\begin{code}
+latex hello_world(.tex)
+\end{code}
+
+如果系统显示类似下面的错误信息,请检查源文件是否有拼写错误。\verb|.log|~文件里有更详细的编译信息。
+\begin{code}
+! LaTeX Error:
+...
+! Emergency stop.
+...
+No pages of output.
+Transcript written on hello_world.log.
+\end{code}
+
+如果编译成功,系统会报出类似下面的信息:
+\begin{code}
+Output written on hello_world.dvi (1 page, 232 bytes).
+Transcript written on hello_world.log.
+\end{code}
+
+每种~\LaTeX~发行包附带不同的~DVI~浏览器,比如~MiKTeX~的是~yap。
+\begin{code}
+yap hello_world(.dvi)
+\end{code}
+
+\section{格式及其转换}
+\subsection{页面描述语言}
+\label{sec:pdl}
+页面描述语言(Page Description Language,PDL)是一种在较高层次上描述实际输出结果的语言。本文只讨论其中三种与~\LaTeX~紧密相关的格式:DVI、PostScript、PDF。
+
+\subsubsection{PostScript}
+最早的打印机只用于打印字符,它使用的硬字符与打字机类似。后来出现的点阵(dot matrix)打字机用一系列的点来“画”出字符,当然它也可以画出图形。当时矢量图的打印只能由绘图仪(plotter)来完成。
+
+1976~年,施乐(Xerox)推出了首台激光打印机,它结合了点阵打印机和绘图仪的优点,可以同时打印高质量的图形和文字。
+
+同一时期,John Warnock~也在酝酿一种类似于~Forth~的图形设计语言,也就是后来的~PostScript(PS),当时他正在旧金山一家电脑图形公司~Evans \& Sutherland~工作。1978~年老板想让~Warnock~搬到位于犹他州的总部,他不想搬家就跳槽到了施乐。
+
+Warnock~和~Martin Newell~开发了新的图形系统~JaM(John and Martin),它后来被合并到施乐的打印机驱动程序~InterPress~中去。这两位还开发过另一个系统~MaJ。
+
+1982~年,Warnock~和施乐研究中心图形实验室主任~Chuck Geschke~一起离开施乐,成立了~Adobe~公司。Newell~后来也加入了~Adobe。
+
+1984~年~Adobe~发布~PS~后不久,Steve Jobs~跑来参观,并建议用它来驱动激光打印机。次年,武装着~PS~驱动的~Apple LaserWriter~横空出世,打响了~80~年代中期桌面出版革命的第一枪。
+
+90~年代中后期,廉价喷墨打印机的流行使得~PS~逐渐式微,因为~PS~驱动对它们毕竟是一个成本负担。
+
+\subsubsection{PDF}
+1993~年,Adobe~推出了一种开放的格式:Portable Document Format(PDF),它于~2007~年成为~ISO 32000~标准。除了开放,PDF~比起~PS~还有一些其它优势:
+\begin{itemize}
+ \item PDF~基本上是~PS~的一个子集,因此更轻便。
+ \item PDF~可以嵌入更先进的字体,具体见\ref{sec:font}节。
+ \item PDF~支持嵌入乱七八糟的东东,比如动画。
+ \item PDF~支持透明图形。
+\end{itemize}
+
+PDF~虽然拥有上述优势,起初它的推广却并不顺利,因为其读写工具~Acrobat~太贵。Adobe~很快推出了免费的~Acrobat Reader(后更名为~Adobe Reader),并不断改进~PDF,终于使它超越了曾经的事实标准~PS,成为网络时代电子文档的新标准。
+
+\subsubsection{DVI}
+\label{sec:dvi}
+Knuth~最初设计的~\TeX~只能用于~XGP~打印机,这台打印机本身还需要一台~PDP-6~主机为它服务。1979~年,David Fuchs\footnote{Fuchs~本科毕业于普林斯顿,1978~年进入斯坦福攻读博士学位。他不是~Knuth~的学生,但是完成过一些~\TeX~的开发任务。他在~Adobe~工作过一段时间,现在混入了娱乐圈,担任过电影《Red Diaper Baby》和《Haiku Tunnel》的制片人。}提出把~\TeX~的输出改为设备无关的格式,也就是~Device Independent format(DVI)。
+
+DVI~只是一种中间格式,用户还需要另外的处理程序(driver)把它转换为其它格式,比如~PS~或~PDF~,甚至~PNG、SVG~等。DVI~不能嵌入字体和图形,PS~和~PDF~可以选择是否嵌入字体。
+
+\subsubsection{Ghostscript}
+\label{sec:ghostscript}
+PS~输出时需要一个解释器(Raster Image Processor,RIP)来把它转换为点阵图形。RIP~可以是软件,也可以是固件(firmware)或硬件\footnote{固件~RIP~在打印机内置处理器上运行,硬件~RIP~常见于高端打印设备。}。
+
+Ghostscript~是一个基于~RIP~的软件包,除了~RIP~它还有一些其它功能,比如处理~EPS,把~PS~转换为~PDF~等。Ghostscript~已经被移植到~Windows、Unix/Linux、Mac OS~等多种操作系统,和它匹配的前端图形用户界面(GUI)有\href{http://pages.cs.wisc.edu/~ghost/}{GSview、Ghostview、gv}等。
+
+\subsection{格式转换}
+\label{sec:convert_format}
+DVI、PS、PDF~等格式的的转换关系如\Fref{fig:convert_format}所示。
+
+\begin{figure}[htbp]
+\centering
+\begin{tikzpicture}
+ \node[box] (tex) {.tex};
+ \node[box] (dvi) [right=5 of tex] {.dvi};
+ \node[box] (pdf) [right=6 of dvi] {.pdf};
+ \node[box] (ps) [above=3 of pdf] {.ps};
+ \path (tex) edge [arrow] node[auto] {latex} (dvi)
+ (dvi) edge [arrow] node[auto] {dvipdfm} (pdf)
+ (dvi.north) [arrow,draw] to node[above,sloped] {dvips} (ps.west)
+ (ps) edge [arrow] node[right] {ps2pdf} (pdf)
+ (tex) edge [arrow,bloop] (pdf);
+ \node [below=.7 of dvi] {pdflatex};
+\end{tikzpicture}
+\caption{格式转换}
+\label{fig:convert_format}
+\end{figure}
+
+最早的~driver~是~\verb|dvips|,它把~DVI~转换为~PS。\verb|dvipdf|~把~DVI~转为~PDF,它后来被~\verb|dvipdfm|~所取代;\verb|dvipdfm|~主要用于处理单字节字符,1999~年之后停止开发;在~\verb|dvipdfm|~基础上发展来的~\verb|dvipdfmx|~可以处理多字节编码(字符编码详见\ref{sec:encoding}节)。
+
+pdf\TeX~是一种特殊的driver,它跳过~DVI,直接用~\TeX~源文件生成~PDF。基于~pdf\TeX~的~pdf\LaTeX~则把\LaTeX~源文件转为~PDF。
+
+包老师倾向于~\verb|dvipdfmx|,因为它对图形格式的兼容性较好,而且擅长处理中文。
+
+得到~DVI~后,我们可以在控制台用以下命令把它转为~PDF。
+\begin{code}
+dvipdfm hello_world(.dvi)
+\end{code}
+
+我们也可以把它转为~PS,接着用~Ghostscript~的一个命令行程序把它转换为~PDF,注意第二个命令需要~\verb|.ps|~后缀。一般情况下不推荐这种方法,因为它多了个步骤。
+\begin{code}
+dvips hello_world(.dvi)
+ps2pdf hello_world.ps
+\end{code}
+
+pdf\LaTeX~用法如下。
+\begin{code}
+pdflatex hello_world(.tex)
+\end{code}
+
+\section{\LaTeX~语句}
+\LaTeX~源文件的每一行称作一条语句(statement),语句可以分三种:命令(command)、数据(data)和注释(comment)。
+
+命令分为两种:普通命令和环境(environment)。普通命令以\verb|\|~起始,大多只有一行;而环境包含一对起始声明和结尾声明,用于多行的场合。命令和环境可以互相嵌套。
+
+数据就是普通内容。注释语句以~\verb|%|~起始,它在编译过程中被忽略。
+
+例如在\ref{sec:hello_world}节例1中,第一行是注释,第二行是普通命令;第三、五行是环境的起始和结尾声明;第四行是数据。
+
+\section{文档结构}
+\subsection{文档类、序言、正文}
+\LaTeX~源文件的结构分三大部分,依次为:文档类声明、序言(可选)、正文。
+
+文档类声明用来指定文档的类型;序言(preamble)用来完成一些特殊任务,比如引入宏包,定义命令,设置环境等;文档的实际内容则放在正文部分。这里的正文指得是\verb|\begin{document}|和\verb|\end|~\verb|{document}|之间的部分,和通常人们心目中的“正文”概念有所出入。
+
+这三部分的基本语法如下:
+\begin{code}
+\documentclass[options]{class} %文档类声明
+\usepackage[options]{package} %引入宏包
+...
+\begin{document} %正文
+...
+\end{document}
+\end{code}
+
+常用的文档类(documentclass)有三种:\verb|article、report、book|,它们的常用选项见\fref{tab:class_options}。
+
+\begin{table}[htbp]
+\centering
+\caption{文档类常用选项}
+\label{tab:class_options}
+\begin{tabularx}{350pt}{lX}
+ \toprule
+ 10pt, 11pt, 12pt & 正文字号,缺省10pt。\LaTeX~会根据正文字号选择标题、上下标等的字号。\\
+ letterpaper, a4paper & 纸张尺寸,缺省是~letter。\\
+ notitlepage, titlepage & 标题后是否另起新页。article~缺省~notitlepage,report~和~book~缺省有~titlepage。\\
+ onecolumn, twocolumn & 栏数,缺省单栏。\\
+ oneside, twoside & 单面双面。article~和~report~缺省单面,book~缺省双面。\\
+ landscape & 打印方向横向,缺省纵向。\\
+ openany, openright & 此选项只用于~report~和~book。report~缺省~openany~,book~缺省~openright。\\
+ draft & 草稿模式。有时某些行排得过满,draft~模式可以在它们右边标上粗黑线提醒用户。\\
+ \bottomrule
+\end{tabularx}
+\end{table}
+
+\LaTeX~的核心只提供基本的功能,系统以宏包(package)的形式提供附加功能或增强原有功能。其它一些编程语言也有类似的模块化机制,比如~C/C++~的~\verb|#include|,Java~的~\verb|import|。
+
+\subsection{标题、摘要、章节}
+
+
+一份文档正文部分的开头通常有标题、作者、摘要等信息,之后是章节等层次结构,内容则散布于层次结构之间。
+
+标题、作者、日期等命令如下,注意\verb|\maketitle|~命令要放在最后。
+\begin{code}
+\title{标题}
+\author{作者}
+\today
+\maketitle
+\end{code}
+
+摘要环境用法如下:
+\begin{code}
+\begin{abstract}
+...
+\end{abstract}
+\end{code}
+
+常用的层次结构命令如下,
+\begin{code}
+\chapter{...}
+\section{...}
+\subsection{...}
+\subsubsection{...}
+\end{code}
+
+每个高级层次可以包含若干低级层次。\verb|article|~中没有~\verb|chapter|,而~\verb|report|~和~\verb|book|~则支持上面所有层次。
+
+\subsection{目录}
+
+我们可以用~\verb|\tableofcontents|~命令来生成整个文档的目录,\LaTeX~会自动设定目录包含的章节层次,也可以用~\verb|\setcounter|~命令来指定目录层次深度。
+\begin{code}
+\tableofcontents
+\setcounter{tocdepth}{2}
+\end{code}
+
+如果不想让某个章节标题出现在目录中,可以使用以下带~\verb|*|~的命令来声明章节。
+\begin{code}
+\chapter*{...}
+\section*{...}
+\subsection*{...}
+\end{code}
+
+类似地,我们也可以用以下命令生成插图和表格的目录,插图和表格功能将在后面章节中介绍。
+
+\begin{code}
+\listoffigures
+\listoftables
+\end{code}
+
+当章节或图表等结构发生变化时,我们需要执行两遍编译命令以获得正确结果。\LaTeX~之所以设计成这样可能是因为当时的电脑内存容量有限。
+
+\section{文字排版}
+\subsection{字符输入}
+文档中可以输入的内容大致可以分为:普通字符、控制符、特殊符号、注音符号、预定义字符串等。而这些内容有两种输入模式:文本模式(缺省)和数学模式,普通的行间(inline)数学模式用\verb|\$...\$|来表示。
+
+\LaTeX~中有些字符(例如~\verb|# $ % ^ & _ { } ~ \|~等)被用作特殊的控制符,所以不能直接输入,多数需要在前面加个~\verb|\|。而~\verb|\|~本身则要用~\verb|\textbackslash|~命令来输入,因为~\verb|\\|~被用作了换行指令。很奇怪为什么不用~C~语言的~\verb|\n|,也许是因为~\TeX~的编程语言是~Pascal。
+
+\begin{code}
+\# \$ \% \^{} \& \_ \{ \} \~{} \textbackslash
+\end{code}
+
+\Fref{tab:symbol}~提供了一些符号的输入方法示例,完整的符号列表见~Scott Pakin的《The Comprehensive \LaTeX~ Symbol List》\citep{Pakin_2008}。
+
+\begin{table}[htbp]
+\centering
+\caption{一些符号和预定义字符串}
+\label{tab:symbol}
+\begin{tabular}{llllll}
+ \toprule
+ \multicolumn{2}{c}{特殊符号} & \multicolumn{2}{c}{注音符号} &
+ \multicolumn{2}{c}{预定义字符串} \\
+ \cmidrule(lr){1-2} \cmidrule(lr){3-4} \cmidrule(lr){5-6}
+ \textcopyright & \verb|\textcopyright| & \aa & \verb|\aa| &
+ \today & \verb|\today| \\
+ \textregistered & \verb|\textregistered| & \AA & \verb|\AA| &

+ \MP & \verb|\MP| \\
+ \dots & \verb|\dots| & \~o & \verb|\~o| & \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\subsection{换行、换页、断字}
+通常~\LaTeX~会自动换行、换页。用户也可以用~\verb|\\|~或~\verb|\newline|~来强制换行;用~\verb|\newpage|~来强制换页。
+
+一般情况下~\LaTeX~会尽量均匀地断字(Hyphenate),使得每一行的字间距分布整齐。但有时我们也需要显式指明断字位置,比如下例就指明~BASIC~这个词不能断开,而~blar-blar-blar~可以在-处断开。
+\begin{code}
+\hyphenation{BASIC blar-blar-blar}
+\end{code}
+
+\subsection{字样、字号}
+
+\LaTeX~会自动调整正文、标题、章节、上下标、脚注等的字样\footnote{关于字样详见\ref{sec:typeface}节}、字号。我们也可以用\fref{tab:typeface_command}中的命令来设置字样;用\fref{tab:fontsize_command}中的命令来设置相对字号,比如正文字号是~10pt、11pt、12pt~时,tiny的字号就分别是~5pt、6pt、6pt。
+
+\LaTeX~有一个特别的字样强调命令:\verb|\emph|,它在不同字样和装饰环境下有不同效果。比如周围文字是正体,它就是斜体;反之它就是正体。
+
+\begin{table}[hbtp]
+\centering
+\caption{字样命令}
+\label{tab:typeface_command}
+\begin{tabular}{llll}
+ \toprule
+ \verb|\textrm{...}| & \textrm{roman} &
+ \verb|\textbf{...}| & \textbf{bold face} \\
+ \verb|\textsf{...}| & \textsf{sans serif} &
+ \verb|\textit{...}| & \textit{italic} \\
+ \verb|\texttt{...}| & \texttt{typewriter} &
+ \verb|\textsl{...}| & \textsl{slanted} \\
+ \\
+ \verb|\emph{...}| & \emph{emphasized} &
+ \verb|\underline{...}| & \underline{underline} \\
+ \verb|\textsc{...}| & \textsc{Small Caps} & & \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\begin{table}[htbp]
+\centering
+\caption{字号命令}
+\label{tab:fontsize_command}
+\begin{tabular}{llll}
+ \toprule
+ & \multicolumn{3}{c}{正文字号} \\
+ \cmidrule(lr){2-4}
+ 命令 & 10pt & 11pt & 12pt \\
+ \midrule
+ \verb|\tiny| & 5pt & 6pt & 6pt \\
+ \verb|\scriptsize| & 7pt & 8pt & 8pt \\
+ \verb|\footnotesize| & 8pt & 9pt & 10pt \\
+ \verb|\small| & 9pt & 10pt & 11pt \\
+ \verb|\normalsize| & 10pt & 11pt & 12pt \\
+ \verb|\large| & 12pt & 12pt & 14pt \\
+ \verb|\Large| & 14pt & 14pt & 17pt \\
+ \verb|\LARGE| & 17pt & 17pt & 20pt \\
+ \verb|\huge| & 20pt & 20pt & 25pt \\
+ \verb|\Huge| & 25pt & 25pt & 25pt \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\section{常用命令环境}
+\subsection{列表}
+
+\LaTeX~中有三种列表环境:\verb|itemize、enumerate、description|,它们的一般用法如下:
+
+\begin{demo}
+\begin{itemize}
+ \item C++
+ \item Java
+ \item HTML
+\end{itemize}
+\end{demo}
+
+\begin{demo}
+\begin{enumerate}
+ \item C++
+ \item Java
+ \item HTML
+\end{enumerate}
+\end{demo}
+
+\begin{demo}
+\begin{description}
+ \item{C++} 一种编程语言
+ \item{Java} 另一种编程语言
+ \item{HTML} 一种标记语言
+\end{description}
+\end{demo}
+
+\subsection{对齐}
+\LaTeX~中的段落缺省两端对齐(fully justified),我们也可以让段落居左、居右或居中对齐。
+
+\begin{demo}
+\begin{flushleft}
+本段落\\
+居左
+\end{flushleft}
+\end{demo}
+
+\begin{demo}
+\begin{flushright}
+本段落\\
+居右
+\end{flushright}
+\end{demo}
+
+\begin{demo}
+\begin{center}
+本段落\\
+居中
+\end{center}
+\end{demo}
+
+\subsection{摘录}
+\LaTeX~中有三种摘录环境:\verb|quote、quotation、verse|。\verb|quote|~两端都缩进,\verb|quotation|~在~\verb|quote|~的基础上增加了首行缩进,\verb|verse|~比~\verb|quote|~多了第二行起的缩进。
+
+\begin{demo}
+正文
+\begin{quote}
+引文两端都缩进。
+\end{quote}
+正文
+\end{demo}
+
+\begin{demo}
+正文
+\begin{quotation}
+引文两端缩进,首行缩进。
+\end{quotation}
+正文
+\end{demo}
+
+\begin{demo}
+正文
+\begin{verse}
+引文两端缩进,第二行起缩进。
+\end{verse}
+正文
+\end{demo}
+
+\subsection{原文照排}
+一般文档中,命令和源代码通常使用等宽字样来表示,也就是原文照排。对此~\LaTeX~提供了~\verb|\verb|~命令(一般用于在正文中插入较短的命令)和~\verb|verbatim|~环境。后者有带~\verb|*|~的版本用来标明空格。
+
+\begin{demo}
+正文中插入\verb|command|
+\begin{verbatim}
+printf("Hello, world!");
+\end{verbatim}
+\begin{verbatim*}
+printf("Hello, world!");
+\end{verbatim*}
+\end{demo}
+
+\subsection{交叉引用}
+我们常常需要引用文档中~\verb|section、subsection、figure、table|~等对象的编号,这种功能叫作交叉引用(cross referencing)。
+
+\LaTeX~中可以用~\verb|\label{marker}|~命令来定义一个标记,标记名可以是任意字符串,但是在全文中须保持唯一。之后可以用~\verb|\ref{marker}|~命令来引用标记处章节或图表的编号,用~\verb|\pageref{marker}|~来引用标记处的页码。
+
+\begin{demo}
+被引用处\label{sec}\\
+...\\
+第\pageref{sec}页\ref{sec}节
+\end{demo}
+
+文档中新增交叉引用后,第一次执行~\verb|latex|~或~\verb|pdflatex|~编译命令时会得到类似下面的警告信息。因为第一次编译只会扫描出有交叉引用的地方,第二次编译才能得到正确结果。
+
+\begin{code}
+LaTeX Warning: There were undefined references.
+...
+LaTeX Warning: Label(s) may have changed. Rerun to get cross-
+references right.
+\end{code}
+
+\subsection{脚注}
+脚注(footnote)的一般用法如下:
+\begin{demo}
+这里是一段正文。\footnote{这里是一段脚注。}
+\end{demo}
+
+\section{长度单位}
+\LaTeX~中的常用长度单位如\Fref{tab:unit}~所示。point~是个传统印刷业采用的单位,而~big point~是~Adobe~推出~PS~时新定义的单位。em~是个相对单位,比如当前字体是~11pt~时,1em~就是~11pt。
+\begin{table}[htbp]
+\caption{常用长度单位}
+\label{tab:unit}
+\centering
+\begin{tabular}{llllll}
+ \toprule
+ in & 英寸 & pt & point, 1/72.27 in & em & 当前字体中字母M的宽度 \\
+ cm & 厘米 & bp & big point, 1/72 in & ex & 当前字体中字母x的高度 \\
+ mm & 毫米 & pc & pica, 12 pt & mu & math unit,1/18 em \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\section{盒子}
+\LaTeX~在排版时把每个对象(小到一个字母,大到一个段落)都视为一个矩形盒子(box),我们在~HTML~和~CSS~中也可以见到类似的模型。
+
+\subsection{mbox~和~fbox}
+
+\LaTeX~中最简单的盒子是~\verb|\mbox|~和~\verb|\fbox|。前者把一组对象组合起来,后者在此基础上加了个边框。
+\begin{demo}
+\mbox{010 6278 5001}
+\fbox{010 6278 5001}
+\end{demo}
+
+\subsection{makebox~和~framebox}
+稍复杂的~\verb|\makebox|~和~\verb|\framebox|~提供了宽度和对齐方式控制选项。这里用~l、r、s~分别代表居左、居右和分散对齐。
+\begin{demo}
+%语法:[宽度][对齐方式]{内容}
+\makebox[100pt][l]{居左}
+\framebox[100pt][r]{居右}
+\end{demo}
+
+\subsection{parbox~和~minipage}
+大一些的对象比如整个段落可以用~\verb|\parbox|~命令和~\verb|\minipage|~环境,两者语法类似,也提供了对齐方式和宽度的选项。但是这里的对齐方式是指与周围内容的纵向关系,用~t、c、b~分别代表居顶、居中和居底对齐。
+
+\begin{demo}
+%语法:[对齐方式]{宽度}{内容}
+\parbox[c]{90pt}{锦瑟无端五十弦,\\一弦一柱思华年。}李商隐
+\end{demo}
+
+细心的读者会发现~\verb|\parbox|~和~\verb|\minipage|~的选项排列顺序和~\verb|\makebox|~和~\verb~\framebox|~的不一致,可能出自不同的作者。

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% we don't look at what happened... in particular, if targetLength is greater
+% than the diameter of the ellipse...
+% the final angle will be around /angle0 + 180. maybe we should treat this pathological case...
+% after iteration, stack contains an angle t such that M(t) is the tail of the arrow
+% to give back the result as a an angle relative to angle0 we could add the following line:
+% angle0 sub 0 exch d

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% we don't look at what happened... in particular, if targetLength is greater
+% than the diameter of the ellipse...
+% the final angle will be around /angle0 + 180. maybe we should treat this pathological case...
+% after iteration, stack contains an angle t such that M(t) is the tail of the arrow
+% to give back the result as a an angle relative to angle0 we could add the following line:
+% angle0 sub 0 exch d

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% we don't look at what happened... in particular, if targetLength is greater
+% than the diameter of the ellipse...
+% the final angle will be around /angle0 + 180. maybe we should treat this pathological case...
+% after iteration, stack contains an angle t such that M(t) is the tail of the arrow
+% to give back the result as a an angle relative to angle0 we could add the following line:
+% angle0 sub 0 exch d

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% we don't look at what happened... in particular, if targetLength is greater
+% than the diameter of the ellipse...
+% the final angle will be around /angle0 + 180. maybe we should treat this pathological case...
+% after iteration, stack contains an angle t such that M(t) is the tail of the arrow
+% to give back the result as a an angle relative to angle0 we could add the following line:
+% angle0 sub 0 exch d
+%
+% begin bug fix 2006-01-11

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% we don't look at what happened... in particular, if targetLength is greater
+% than the diameter of the ellipse...
+% the final angle will be around /angle0 + 180. maybe we should treat this pathological case...
+% after iteration, stack contains an angle t such that M(t) is the tail of the arrow
+% to give back the result as a an angle relative to angle0 we could add the following line:
+% angle0 sub 0 exch d

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% we don't look at what happened... in particular, if targetLength is greater
+% than the diameter of the ellipse...
+% the final angle will be around /angle0 + 180. maybe we should treat this pathological case...
+% after iteration, stack contains an angle t such that M(t) is the tail of the arrow
+% to give back the result as a an angle relative to angle0 we could add the following line:
+% angle0 sub 0 exch d

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% we don't look at what happened... in particular, if targetLength is greater
+% than the diameter of the ellipse...
+% the final angle will be around /angle0 + 180. maybe we should treat this pathological case...
+% after iteration, stack contains an angle t such that M(t) is the tail of the arrow
+% to give back the result as a an angle relative to angle0 we could add the following line:
+% angle0 sub 0 exch d

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% we don't look at what happened... in particular, if targetLength is greater
+% than the diameter of the ellipse...
+% the final angle will be around /angle0 + 180. maybe we should treat this pathological case...
+% after iteration, stack contains an angle t such that M(t) is the tail of the arrow
+% to give back the result as a an angle relative to angle0 we could add the following line:
+% angle0 sub 0 exch d

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% given a target length (targetLength) and an initial angle (angle0) [in the stack],
+% let M(angle0)=(rx*cos(angle0),ry*sin(angle0))=(x0,y0).
+% This computes an angle t such that (x0,y0) is at distance
+% targetLength from the point M(t)=(rx*cos(t),ry*sin(t)).
+% NOTE: this an absolute angle, it does not have to be added or substracted to angle0
+% contrary to TvZ's code.
+% To achieve, this, one iterates the following process: start with some angle t,
+% compute the point M' at distance targetLength of (x0,y0) on the semi-line [(x0,y0) M(t)].
+% Now take t' (= new angle) so that (0,0) M(t') and M' are aligned.
+%
+% Another difference with TvZ's code is that we need d (=add/sub) to be defined.
+% the value of d = add/sub is used to know on which side we have to move.
+% It is only used in the initialisation of the angle before the iteration.

+% than the diameter of the ellipse...
+% the final angle will be around /angle0 + 180. maybe we should treat this pathological case...
+% after iteration, stack contains an angle t such that M(t) is the tail of the arrow
+% to give back the result as a an angle relative to angle0 we could add the following line:

+\chapter{字体}
+
+关于字体有三个重要概念:glyph、typeface、font。glyph~通常被翻译为字形,也有翻译为字体的;typeface~是一个书法和印刷领域的概念,它通常被翻译为字体或书体;font~曾经和~typeface~混用,但现在一般用作电脑领域的概念,在中国大陆被翻译为字体,在台湾被翻译为字型。
+
+上述翻译的混乱令人十分无奈,包老师决定在本文中把它们分别翻译为字形、字样、字体,以正视听。
+
+字形是一个字符的具体图形表现形式,一个字符可以有多个字形,比如汉字中的“強/强”、“戶/户/戸”;字样是一组相同风格样式的字形的集合,比如中文字样有宋、仿、楷、黑、隶、篆等;一种字样可以对应电脑上的几种字体。
+
+\section{字样}
+\label{sec:typeface}
+拉丁字母的字样主要有三大类:Serif(Roman)、Sans Serif~和~Mono-space~(Typewriter)。Serif~的笔画边缘部分有些装饰,类似于中文的宋体、仿宋、楷体、魏书等。Sans Serif~的笔画则是平滑的,类似于中文的黑体。Sans~这个词来源于法语,就是“没有”的意思。Monospace~则是等宽字样。
+
+每一类字样都可以有加粗(bold)、斜体(italic)、倾斜(oblique)等修饰效果。Italic~通常对原字样进行过重新设计,它修饰精细,多用于~Serif;~Oblique~也称作~slanted,基本上是把正体倾斜,多用于~Sans Serif。通常~oblique~看起来比~italic~要宽一些。
+
+\Fref{tab:typeface}列出了几种常见的字样。
+
+\begin{table}[htbp]
+\caption{常见字样}
+\label{tab:typeface}
+\centering
+\begin{tabular}{llll}
+ \toprule
+ 操作系统 & Serif & Sans Serif & Monospace \\
+ \midrule
+ Mac OS & Times & Helvetica & Courier \\
+ Windows & Times New Roman & Arial & Courier New \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\section{字体格式}
+\label{sec:font}
+
+\subsection{点阵字体和矢量字体}
+电脑上用的字体(font)按数据格式可以分为三大类:点阵字体(bitmap)、轮廓(outline)字体和笔画(stroke-based)字体。
+
+点阵字体通过点阵来描述字形。早期的电脑受到容量和绘图速度的限制,多采用点阵字体。点阵字体后来渐渐被轮廓字体所取代,但是很多小字号字体仍然使用它,因为这种情况下轮廓字体缩放太多会导致笔画不清晰。
+
+轮廓字体又称作矢量字体,它通过一组直线段和曲线来描述字形。轮廓字体易于通过数学函数进行缩放等变换,形成平滑的轮廓。轮廓字体的主要缺陷在于它所采用的贝塞尔曲线(Bézier curves)在光栅(raster)设备(比如显示器和打印机)上不能精确渲染,因而需要额外的补偿处理比如字体微调(font hinting)。但是随着电脑硬件的发展,人们一般不在意它比点阵字体多出的处理时间。
+
+笔画字体其实也是轮廓字体,不过它描述的不是完整的字形,而是笔画。它多用于东亚文字。
+
+\subsection{常见字体}
+
+常见的轮廓字体技术有:Type 1~和~Type 3、TrueType、OpenType、~\MF~等。
+
+Adobe~的~Type 1~和~Type 3~基于~PS,它们采用三次贝塞尔曲线。Type 1~支持微调,它使用一个简化的~PS~子集;Type 3~不支持微调,但它可以使用全部~PS~功能,因此既可以包含轮廓字体也可以包含点阵字体信息。
+
+1991~年,Apple~发布了~TrueType,它采用二次贝塞尔曲线。二次曲线处理起来比三次曲线快,但是需要更多的点来描述。所以从~TrueType~到~Type 1的转换是无损的,反之是有损的。1994~年,Apple~着手研究~TrueType~的下一代技术:TrueType GX,它后来演变为Apple Advanced Typography(AAT)。
+
+1996~年,微软和~Adobe~联合发布了~OpenType。它比起~AAT~的优势有:跨平台、开放和易于开发、支持更多的语言比如阿拉伯语。
+
+早在~1984~年~Knuth~就发布了~\MF,它与~TrueType~和~OpenType的区别是,不直接描述字形轮廓,而描述生成轮廓的笔的轨迹。笔的形状可以是椭圆形或多边形,尺寸缩放自如,字形边缘也柔和一些。两种字体可以用同一个~\MF~文件,当然还有不同的参数。\MF~技术如此先进,却没有流行开来。对此~Knuth~解释道,要求一位设计字体的艺术家掌握~60~个参数太变态了,那是用来折磨数学家的。
+
+Type 1~和~Type 3~把字体信息存储在两种文件里:metrics~和~glyph~文件。metrics~文件有~AFM(Adobe font metrics)和~PFM(printer font metrics),glyph~文件有~PFA(printer font ASCII)和~PFB(printer font binary)。~\LaTeX~使用的~metrics~格式是~TFM(TeX Font Metrics)。
+
+TrueType~的文件后缀是~.ttf,OpenType~的是~.ttf~和~.otf。\MF~虽然用矢量图形来定义字形,实际输出的却是一种点阵格式:PK~(packed raster)。
+
+上述字体按技术的先进性,从高到低的排序为:OpenType、~TrueType、Type 1、Type 3、PK,我们应优先选用~OpenType~和~TrueType。
+
+\subsection{合纵连横}
+Adobe~收取的~Type 1~专利许可费一度十分昂贵,穷人们只好用免费的~Type 3。为了打破这种垄断,Apple~开发了~TrueType。1991~年~TrueType~发布之后,Adobe随即公开了~Type 1~的规范,~Type 1~字体从贵族堕落为平民,因而流行开来。
+
+1980~年代中后期,Adobe~的大部分盈利来自于~PS~解释器的许可费。面对这种垄断局面,微软和~Apple~联合了起来。微软把买来的~PS~解释器~TrueImage~授权给~Apple,Apple~则把~TrueType~授权给微软。
+
+微软得陇望蜀,又企图获得~AAT~的许可证,未遂。为了打破~Apple~的垄断,微软联合~Adobe~在1996年发布了~OpenType。Adobe~在2002~年末将其字体库全面转向~OpenType。
+
+上面这几出精彩好戏充分展示了商场上的勾心斗角、尔虞我诈,没有永恒的伙伴,只有永恒的利益。但它同时也告诉我们,市场竞争中受益的还是广大的消费者。
+
+\section{字体应用}
+
+PS~支持~Type 1~和~Type 3,而~PDF~除了这两种还支持~TrueType~和~OpenType。\verb|latex|、DVI浏览器、各种~driver~分别采用不同的字体技术。
+
+\subsection{DVI}
+\verb|latex|~编译~\LaTeX~源文件生成~DVI~时只需要\verb|.tfm|~文件,因为~DVI~并不包含字形信息,而只包含对字体的引用。DVI~浏览器显示~DVI~时一般使用~PK,它在系统中查找相应的~\verb|.pk|~文件,若找不到就调用~\MF~在后台自动生成。
+
+\subsection{dvips}
+缺省情况下,\verb|dvips|~也会查找~\verb|.pk|~,或调用~\MF~自动生成;然后把~PK~转换成包含点阵字体的~Type 3,它的参数~\verb|-D|~可以用来控制该点阵字体的分辨率。用~\verb|ps2pdf|~处理含~Type 3~的~PS~时,输出的自然是含~Type 3~的~PDF。
+
+GSview~在低分辨率下可以很好地渲染~Type 3,Adobe Reader~或~Acrobat~却不能,因为它们使用的~Adobe Type Manager~不支持包含完整~PS~的~Type 3。含~Type 3~的~PDF~看起来会有些模糊,所以应尽量避免使用。
+
+\verb|dvips|~的另一个参数~\verb|-Ppdf|~把~Type 1~嵌入生成的~PS,这样再~\verb|ps2pdf|~就能生成含~Type 1~的~PDF。
+
+\verb|dvips|~不支持真正的(native)TrueType,用户只能把~TrueType~先转成~PK~或~Type 1,这样绕了个弯效果总会打些折扣。
+
+\verb|dvips|~的字体详细使用方法可查阅其手册\citep{Rokicki_2005}第~6~章,此处不赘述。
+
+\subsection{dvipdfm(x)}
+\verb|dvipdfm|~支持~PK~和~Type 1,它可以用一个~\verb|t1fonts.map|~文件建立~PK~文件和~Type 1~文件之间的映射,这样生成的~PDF~用的就是~Type 1。\verb|dvipdfm|~也不支持真正的~TrueType。
+
+\verb|dvipdfmx|~通过正确的设置可以使用真正的~TrueType,它对中日韩等东亚文字的支持也较好,所以它对我们来说是~Driver~的首选。
+
+\section{TrueType~字体安装配置}
+CJK~自带的~UTF-8~编码字体~gbsn~和~gkai只包含~GB2312~字符集,而~CTeX~只提供~GBK~编码字体,因此中文用户通常需要自己安装配置~UTF-8~编码的~TrueType~字体。
+
+在使用~TrueType~之前,用户通常需要作以下准备工作:
+\begin{enumerate}
+ \item 用转换程序~\verb|ttf2tfm|~生成~TFM。
+ \item 配置字体定义文件~\verb|.fd|。
+ \item 配置~\verb|ttf2pk|~,因为~DVI~浏览器和~\verb|dvips|~都会自动调用~\verb|ttf2pk|~来生成~PK。
+ \item 配置~\verb|dvipdfmx|。
+\end{enumerate}
+
+\subsection{目录和文件}
+通常每个发行包都会参照~TDS~建立自己的目录系统,把各种文件发在固定的位置。比如~MiKTeX~顶层目录如下,在本节后面的示例中我们将使用这些目录的缩写。
+\begin{code}
+Install: D:\edit\MiKTeX 2.7
+UserData: C:\Documents and Settings\Alpha\Local Settings\
+ Application Data\MiKTeX\2.7
+UserConfig: C:\Documents and Settings\Alpha\
+ Application Data\MiKTeX\2.7
+\end{code}
+
+目录多了有个缺点,文件不知道放在哪里好。MiKTeX~中有的配置文件居然在四个目录下各有一份,实在是令人发指。幸好我们可以用下面的命令检查配置文件的具体名字和路径。
+
+\begin{code}
+initexmf --edit-config-file=ttf2pk
+\end{code}
+
+\subsection{ttf2tfm}
+比如我们想把~\verb|SimSun18030.ttc|(18030~字符集的新宋体)转换为~UTF8~编码的字体文件,我们需要执行以下步骤。
+
+\begin{enumerate}
+ \item 把需要的~\verb|.ttf|~文件复制到~\verb|UserData/fonts/truetype/chinese/|。
+ \item 用下面的命令生成\verb|.tfm|~和~\verb|.enc|~文件。
+ \item 把~\verb|*.tfm|~复制到~\verb|UserData/fonts/tfm/chinese/utf8song/|。
+ \item 把~\verb|*.enc|~复制到~\verb|UserData/fonts/enc/chinese/utf8song/|。
+\end{enumerate}
+
+\begin{code}
+ttf2tfm SimSun18030.ttc -q -w utf8song@Unicode@
+\end{code}
+
+\subsection{字体定义文件}
+字体定义文件将字体引用名和实际的字体文件联系起来,比如我们在~\verb|CJK|~环境中引用~\verb|usong|~时,系统将会找到并使用~\verb|utf8song*.tfm|。
+
+\begin{code}
+%UserData\tex\latex\CJK\UTF8\C70usong.fd
+\ProvidesFile{c70usong.fd}
+%character set: GB18030
+%font encoding: Unicode
+\DeclareFontFamily{C70}{usong}{\hyphenchar \font\m@ne}
+\DeclareFontShape{C70}{usong}{m}{n}{<-> CJK * utf8song}{}
+\DeclareFontShape{C70}{usong}{m}{it}{<-> CJK * utf8song}{}
+\DeclareFontShape{C70}{usong}{bx}{n}{<-> CJKb * utf8song}{
+ \CJKbold}
+\endinput
+\end{code}

+\subsection{配置~\texttt{ttf2pk}}
+MiKTeX~中~\verb|ttf2pk|~的配置文件是~\verb|ttf2pk.ini|~,在其它的发行包中可能是~\verb|ttf2pk.cfg|。
+
+\verb|ttf2pk.ini|~中有一个~\verb|.map|~文件列表,后者定义了~TrueType~应该按编码转为~PK~等信息。
+
+比如下面这个文件列表会让~\verb|ttf2pk|~读取~\verb|foo.map|~和~\verb|bar.map|。
+
+\begin{code}
+map foo.map
+map bar.map
+\end{code}
+
+如果系统找不到~\verb|ttf2pk.ini|,它会缺省使用~\verb|ttfonts.map|。
+\begin{code}
+%UserData\ttf2tfm\base\ttfonts.map
+utf8song@Unicode@ SimSun18030.ttc

+\subsection{配置~\texttt{dvipdfmx}}
+配置~\verb|dvipdfmx|~是为了让~PDF~正确地嵌入~TrueType,否则生成的文件中的内容不能复制、粘贴。

+
+当年~Knuth~开发~\TeX~时,GIF、JPEG、PNG、EPS~等图形格式还没有问世,所以~DVI~不能直接支持这些格式。但是高手就是高手,Knuth~在~\TeX~上留了一个后门:\verb|\special|~命令,让后面的~Driver~决定怎样处理图形。
+
+这和当年老毛把港澳台,老邓把钓鱼岛都“留给后人解决”有异曲同工之妙。曾经有位出版社的编辑看上了包老师写的一个程序,要包老师改改当作教学辅助软件出版,但是包老师手头没有~DOS~中断的资料没办法加鼠标操作。该编辑说:你把鼠标驱动打包在软件里,让用户自己琢磨是怎么回事。
+
+下面我们会在~\ref{sec:graphics_format}~节介绍一下~\LaTeX~所用图形格式,\ref{sec:includegraphics}~节介绍怎样插入已有的图形,\ref{sec:mp}--\ref{sec:pgf}~节讨论怎样制作矢量图形。
+
+\section{图形格式}
+\label{sec:graphics_format}
+
+\LaTeX~支持点阵图形格式~JPEG~和~PNG,也支持矢量格式~EPS~和~PDF。对于示意图,我们应该首选矢量格式;包含大量自然色彩的图像(比如照片)应该选~JPEG,人工点阵图像应该选~PNG。
+
+\subsection{EPS}
+80~年代中后期,PS~风头之劲一时无两,人们自然会考虑把它作为文档中嵌入图形的标准格式。然而~PS~实在太强大,人们担心嵌入文档的~PS~会搞破坏,于是就产生了戴着手铐的~Encapsulated PostScript(EPS)。出于同样的原因,人们也担心嵌入~HTML~的~ActiveX、Java Applet、JavaScript~中混入恶意代码,所以才会对它们也有所限制。
+
+早年间~DVI~经常被转换为~PS,所以~EPS~就成了~\LaTeX~的标准图形格式。
+
+\subsection{Driver~们的口味}
+
+\subsubsection{dvips}
+\verb|dvips|~喜欢~PS,所以就爱屋及乌只支持嵌入~EPS。MiKTeX~看不惯这种垄断行为,就把~\verb|dvips|~破解,添加了对~JPEG~和~PNG~的支持。如果你反对这种黑客破解行径,只好找软件把其它图形格式转换为~EPS。
+
+\subsubsection{pdf\LaTeX}
+pdf\LaTeX~支持~JPEG、PNG和PDF,不支持~EPS。传说pdf\LaTeX~不支持~EPS~的原因是~PS~解释器的版权问题。包老师认为这种说法不可信,因为~1997~年~Hàn The Thành~发布~pdf\TeX~时~PS~已经被~PDF~赶超,Adobe~与其保护~PS~还不如保护~PDF。
+
+\LaTeX~有两个宏包~\verb|epstopdf|~和~\verb|pst-pdf|~可以实时地(on the fly)把~EPS~转换为~PDF\footnote{在这里on the fly是指在后台处理,用户不用操心。包老师不确定把它翻译为“实时”是否合适,因为~real time~通常被翻译为实时。对于用户无须干涉、知情的情况,有人说~user transparent,也有人说~black box,语言还真奇妙。}。然而前者有安全漏洞,后者用法繁琐,用户最好还是用其它软件事先把~EPS~转为~PDF。
+
+\subsubsection{dvipdfm}
+\verb|dvipdfm|~支持~JPEG、PNG、PDF,不支持~EPS,但是它可以实时地调用~Ghostscript~把~EPS~转为~PDF。所以从图形格式支持的角度来讲,\verb|dvipdfm|~比~\verb|dvips|~和~pdf\LaTeX~都好。
+
+那位同学说了,你这么多废话作甚,直接告诉我们用~\verb|dvipdfm|~不就完了。然而你别忘了~\verb|dvipdfm|~需要~DVI~作为输入,不幸的是用来生成~DVI~的~\verb|latex|~对~JPEG~和~PNG~有意见。
+
+综上所述,这些~driver~都不能把图形格式痛快地通吃,所以同学们别着急,且听包老师慢慢忽悠怎样转换和处理图形格式。
+
+\subsection{图形格式转换}
+
+注意把点阵图形转换为矢量图形并不能提高图形本身的质量,正所谓“garbage in, garbage out”。
+
+\subsubsection{JPEG~和~PNG~的范围框}
+
+作为中间格式的~DVI~不包含图形本身,它只记录图形的尺寸和文件名,因为具体的图形处理由后面的~driver~负责。DVI~中图形的尺寸来自它的范围框(bounding box),而~\verb|latex|~无法从点阵图形文件中提取这一信息,所以我们需要以某种方式把范围框信息告诉它。
+
+一种方法是打开图形文件,记下尺寸,插入图形时加上相应的参数。
+
+另一种方法用~\verb|ebb|~程序生成一个含范围框信息的文件。比如下例会生成~\verb|graph.bb|~文件,有了它插入图形时就不需要范围框参数。注意有时此程序算出的范围框不准,不知道是它的~bug~还是包老师的人品问题。
+\begin{code}
+ebb graph.jpg
+\end{code}
+
+\subsubsection{其它格式转为EPS}
+有很多程序都可以把点阵图形转换为~EPS,比如~\href{http://www.imagemagick.org/}{ImageMagick},以及~\href{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=dvipsgraphics}{~a2ping/sam2p、bmeps、jpeg2ps、sam2p}~等。
+
+PS~从~Level 2~开始才支持点阵图形压缩,所以在把其它格式转为~EPS~时应尽量使用~Level 2~或~3,否则输出的~EPS~会很大。
+
+下面是一个~ImageMagick~中~\verb|convert|~程序的例子。
+\begin{code}
+convert photo.jpg eps2:photo.eps
+\end{code}
+
+另外还有一种~PS~虚拟打印机的方法,优点是可以把几乎所有文件“打印”成~EPS,缺点是输出的是~PS Level 1,即使驱动程序提供了其它~Level~的选项。
+
+\begin{enumerate}
+\item 找一个~PS~打印机驱动程序。Windows~安装盘附带很多打印机驱动,其中带~PS~字样的就是~PS~驱动。包老师选的是“HP Color LaserJet 8550-PS”,Adobe~提供的~PS~驱动效果不太好。其它驱动安装过程可能稍有不同。
+\item 安装时端口选“FILE”,或者后面打印时选择“Print to File”。高级选项里的~PS~选项选“Encapsulated PostScript (EPS)”。
+\item 打开点阵图形文件,打印到上面的虚拟打印机,输出的文件就是~EPS,但是它没有范围框。
+\item 用~GSview~打开上面生成的~EPS,不用理会没范围框的警告,Options~菜单里选上“EPS Clip”,用~File~菜单的“PS to EPS”生成含范围框的~EPS。
+\end{enumerate}
+
+\subsubsection{其它格式转为~PDF}
+
+\LaTeX~附带的~\verb|epstopdf|~程序\footnote{这个命令行程序和上面提到的~epstopdf~宏包是两样东西。}可以把~EPS~转为~PDF。类似地我们也可以安装一个~PDF~虚拟打印机,用它来把其它图形文件转为~PDF。
+
+\section{插入图形}
+\label{sec:includegraphics}
+
+\subsection{插入命令}
+如今万事俱备,只欠插入。上回讲到哪儿来着?Yeah,~Knuth~的后门~\verb|\special|。
+
+用低级命令~\verb|\special|~来插入图形很不爽,于是~\LaTeX~v2.09~增加了~\verb|epsf|~和~\verb|psfig|~宏包。之后~\LaTeXe~推出了更好的~\verb|graphics|~和~\verb|graphicx|~宏包,这两个宏包有个共同的命令:\verb|\includegraphics|。\verb|graphicx|~版本的语法更简单,功能更强大,所以一般推荐用它。
+
+插入图形的具体命令如下,如果是点阵图形需要加范围框参数(左上角和右下角坐标)。
+
+\begin{code}
+\includegraphics[bb=0 0 410 307]{photo.jpg}
+\end{code}
+
+若想省略文件后缀,可在插入图形前使用两个命令。前者指定一个后缀列表,让~\LaTeX~自行查找;后者告诉~\LaTeX~未知后缀的都是~EPS。
+\begin{code}
+\DeclareGraphicsExtensions{.eps,.mps,.pdf,.jpg,.png}
+\DeclareGraphicsRule{*}{eps}{*}{}
+\end{code}
+
+\subsection{缩放、旋转}
+\Fref{tab:scale_angle}~和\Fref{tab:clip}~的选项可以用来缩放、旋转和裁剪插图。
+
+\begin{table}[htbp]
+\caption{includegraphics~命令的缩放和旋转选项}
+\label{tab:scale_angle}
+\centering
+\begin{tabularx}{350pt}{lX}
+ \toprule
+ scale & 缩放比例 \\
+ width & 宽度 \\
+ height & 高度 \\
+ totalheight & 范围框高度,旋转时它不等于高度 \\
+ keepaspectratio & 如果不使用它而同时指定插图的宽度、高度,长宽比可能会失调;使用它时长宽比不变,宽度、高度都不超过指定参数 \\
+ angle & 旋转角度 \\
+ origin & 旋转原点 \\
+ \bottomrule
+\end{tabularx}
+\end{table}
+
+\begin{table}[htbp]
+\caption{includegraphics~命令的裁剪选项}
+\label{tab:clip}
+\centering
+\begin{tabularx}{350pt}{lX}
+ \toprule
+ viewport & 可视区域的左上角和右下角坐标。\\
+ trim & 左、下、右、上四边裁剪的数值。\\
+ clip & 是否真正裁剪。缺省为false,不执行裁剪,多出的部分就那样放着;设置为true时执行裁剪。似乎是多此一举。\\
+ \bottomrule
+\end{tabularx}
+\end{table}
+
+若想深入了解~\LaTeX~插入图形的功能,请参考~Keith Reckdahl~的《Using Imported Graphics in \LaTeX~ and pdf\LaTeX》\citep{Reckdahl_2006}(简称epslatex)。
+
+\subsection{figure环境}
+插图通常需要占据大块空白,所以在文字处理软件中用户经常需要调整插图的位置。\LaTeX~有一个~\verb|figure|~环境可以自动完成这样的任务,这种自动调整位置的环境称作浮动环境。
+
+\begin{code}
+\begin{figure}[htbp]%位置选项
+\centering
+\includegraphics[bb=0 0 410 307,scale=.8]{photo}
+\caption{10个月大的Anna}
+\label{fig:anna}
+\end{figure}
+\end{code}
+
+\begin{figure}[htbp]
+\centering
+\includegraphics[bb=0 0 410 307,scale=.8]{dscf4684}
+\caption{10个月大的Anna}
+\label{fig:anna}
+\end{figure}
+
+上述代码中,\verb|[htbp]|~选项用来指定插图排版的理想位置,这几个字母分别代表~here、top、bottom、float page,也就是固定位置、页顶、页尾、单独的浮动页。我们可以使用这几个字母的任意组合,一般不推荐单独使用~\verb|[h]|,因为那个位置也许很不合适,\LaTeX~会很生气。
+
+\verb|\centering|~用来使插图居中,\verb|\caption|~命令设置插图标题,\LaTeX~会自动给浮动环境的标题加上编号。注意~\verb|label|~应放在\verb|caption|~之后,否则引用时指向的是前一个插图。
+
+\subsection{插入多幅图形}
+\subsubsection{并排摆放,共享标题}
+当我们需要两幅图片并排摆放,并共享标题时,可以在~\verb|figure|~环境中使用两个~\verb|\includegraphics|~命令。
+
+\begin{fdemo}{
+\centering
+\includegraphics[scale=2]{examples/subfig_left.mps}
+\includegraphics[scale=2]{examples/subfig_right.mps}
+\captionof{figure}{反清复明}
+}
+\begin{figure}[htbp]
+\centering
+\includegraphics{left}
+\includegraphics{right}
+\caption{反清复明}
+\end{figure}
+\end{fdemo}
+
+\subsubsection{并排摆放,各有标题}
+如果想要两幅并排的图片各有自己的标题,可以在~\verb|figure|~环境中使用两个~\verb|minipage|~环境,每个环境里插入一个图。
+\begin{code}
+\begin{figure}[htbp]
+\centering
+\begin{minipage}[t]{0.3\textwidth}
+ \centering
+ \includegraphics{left}
+ \caption{清明}
+\end{minipage}
+\end{code}
+\begin{code}
+\begin{minipage}[t]{0.3\textwidth}
+ \centering
+ \includegraphics{right}
+ \caption{反复}
+\end{minipage}
+\end{figure}
+\end{code}
+
+\begin{figure}[htbp]
+\centering
+\begin{minipage}[t]{0.3\textwidth}
+ \centering
+ \includegraphics[scale=2]{examples/subfig_left.mps}
+ \caption{清明}
+\end{minipage}
+\begin{minipage}[t]{0.3\textwidth}
+ \centering
+ \includegraphics[scale=2]{examples/subfig_right.mps}
+ \caption{反复}
+\end{minipage}
+\end{figure}
+
+\subsubsection{并排摆放,共享标题,各有子标题}
+如果想要两幅并排的图片共享一个标题,并各有自己的子标题,可以使用~\verb|subfig|~宏包提供的~\verb|\subfloat|~命令。
+
+\verb|subfloat|~命令缺少宽度参数。虽然我们可以用~\verb|\hspace|~命令调整子图的距离,子标题却只能和子图本身一样宽,就会出现折行。
+\begin{code}
+\usepackage{subfig}
+\begin{figure}[htbp]
+\centering
+\subfloat[清明]{
+ \label{fig:subfig_a}
+ \includegraphics{left}
+}
+\hspace{80pt}
+\subfloat[反复]{
+ \label{fig:subfig_b}
+ \includegraphics{right}
+}
+\caption{反清复明}
+\end{figure}
+\end{code}
+
+每个子图可以有各自的引用,就象这个样子:\Fref{fig:subfig_a}、\Fref{fig:subfig_b}。
+\begin{figure}[htbp]
+\centering
+\subfloat[清明]{
+ \label{fig:subfig_a}
+ \includegraphics[scale=2]{examples/subfig_left.mps}
+}
+\hspace{80pt}
+\subfloat[反复]{
+ \label{fig:subfig_b}
+ \includegraphics[scale=2]{examples/subfig_right.mps}
+}
+\caption{反清复明}
+\end{figure}
+
+\subsubsection{改进的子图方法}
+为了避免子标题折行,我们可以在~\verb|\subfloat|~里再嵌套个~\verb|minipage|,因为后者是有宽度的。
+\begin{code}
+\begin{figure}[htbp]
+\centering
+\subfloat[清明]{
+\label{fig:improved_subfig_a}
+\begin{minipage}[t]{0.3\textwidth}
+ \centering
+ \includegraphics{left}
+\end{minipage}
+}
+\subfloat[反复]{
+\label{fig:improved_subfig_b}
+\begin{minipage}[t]{0.3\textwidth}
+ \centering
+ \includegraphics{right}
+\end{minipage}
+}
+\caption{反清复明}
+\end{figure}
+\end{code}
+
+\begin{figure}[htbp]
+\centering
+\subfloat[清明]{
+\begin{minipage}[t]{0.3\textwidth}
+ \centering
+ \includegraphics[scale=2]{examples/subfig_left.mps}
+\end{minipage}
+}
+\subfloat[反复]{
+\begin{minipage}[t]{0.3\textwidth}
+ \centering
+ \includegraphics[scale=2]{examples/subfig_right.mps}
+\end{minipage}
+}
+\caption{反清复明}
+\end{figure}
+
+\section{图形绘制工具比较}
+与~\LaTeX~配套使用的绘图工具主要有三种:\MP、PSTricks~和~PGF,它们的特点如下。
+
+\begin{itemize}
+\item 工作方式。\MP~离线绘图,生成的~EPS~可以插入~\LaTeX~文档;PSTricks~和~PGF~都采用在线绘图的方式,也就是~\LaTeX~文档内直接使用绘图命令。
+\item 兼容性。\MP~生成的~MPS~需要先转为~PDF~才能被~pdf\LaTeX~使用;PSTricks~生成的~EPS和~pdf\LaTeX~不兼容;PGF~提供针对各种~driver~的接口,兼容性最好。
+\item 功能。PSTricks~有~PS~作后盾,功能最强;\MP~擅长处理数学内容;PGF~的流程图有独到之处。
+\end{itemize}
+
+限于篇幅,本文只对这三种工具进行简介。除了它们,用户也可以考虑一些面向~\LaTeX~的绘图前端,比如~Unix/Linux~下的~xfig~和~Windows~下的~TpX;或可以输出~EPS~的专用软件,比如~gnuplot~和~Matlab。
+
+\section{\MP}
+\label{sec:mp}
+
+1989~年~John D. Hobby\footnote{Hobby 1985年从斯坦福获博士学位,导师就是Knuth,现供职于贝尔实验室。}开始设计一种绘图语言及其编译器,也就是~\MP。\MP~从~\MF~那里获得了大量灵感和源代码,学生从导师那里顺点东西自然是手到擒来。\MP~和~\MF~语法类似,\MP~的主要优点在于是它输出的是~EPS,而且支持彩色;\MF~输出的是点阵格式,不支持彩色。Knuth~声称自己画图时只用~\MP。
+
+从~Hobby~主页上~\MP~的更新记录看,它的最后版本是~0.63,年份是~1994。目前~Taco Hoekwater\footnote{他也是LuaTeX开发者之一。}继续~\MP~的开发工作,最新版本是~1.005。
+
+本文只对~\MP~作简单介绍,若想深入了解请参阅~Hobby~的《A User's Manual for MetaPost》\citep{Hobby_2007}。
+
+\subsection{准备工作}
+用户一般需要把~\MP~源文件(.mp)用一个命令行程序~\verb|mpost|~编译为一种特殊的~EPS,也称作~MPS,然后再把~MPS~插入~\LaTeX~源文件中使用。
+\begin{figure}[htbp]
+\centering
+\begin{tikzpicture}
+ \node[box] (mp) {.mp};
+ \node[box, right=5 of mp] (mps) {.mps};
+ \path (mp) edge [arrow] node[auto] {mpost} (mps);
+\end{tikzpicture}
+\caption{MetaPost~的编译}
+\label{fig:mp}
+\end{figure}
+
+一个~\MP~源文件可以包含多个图形,一般形式如下。代码中每行语句以~\verb|;|~结尾,注释行以~\verb|%|~起始。每个图形的绘图命令包含在一对起始和结尾声明之间。文件结尾也要有一个结尾声明。
+\begin{code}
+beginfig(1); %图形起始
+... %绘图命令
+endfig; %图形结尾
+
+beginfig(2);
+...
+endfig;
+...
+end; %文件结尾
+\end{code}
+
+假如上面的源文件名字是~\verb|fig.mp|,我们可以执行以下编译命令。
+\begin{code}
+mpost fig(.mp)
+\end{code}
+
+编译后就会生成“fig.1、fig.2、$\cdots$”~等文件,每个文件的后缀就是相应的图形起始声明的编号。所以此编号在一个源文件中应保持唯一,否则后生成的文件就会覆盖前面的。
+
+这样的文件名管理起来很麻烦,插入它们时也不能省略后缀,因为~\LaTeX~不能识别它们。用~\verb|\DeclareGraphicsExtensions|~来逐一声明后缀看起来很傻,自己改文件名更傻,\verb|\DeclareGraphicsRule|~也显得不够严谨。
+
+然而~\MP~已经考虑到这个问题,为此提供了一个文件名模板命令。把下面的代码加到源文件头部,编译输出的文件名就会是“fig-01.mps、fig-02.mps、$\cdots$”。
+\begin{code}
+filenametemplate "%j-%2c.mps"; %加在源文件头部
+\end{code}
+
+我们也可以把这个命令加在每个图形的起始声明之前,指定个性化的输出文件名,这样可能更便于记忆。
+\begin{code}
+filenametemplate "flowchart.mps" %加在每个图形前面
+\end{code}
+
+MPS~可以用~GSview~查看,我们也可以用以下命令把它转为~PDF~再用~Adobe Reader~查看。
+
+\begin{code}
+epstopdf flowchart.mps
+\end{code}
+
+\subsection{基本图形对象}
+为了节省空间,本节后面的示例会略去图形起始声明和结尾声明等不重要的细节。
+
+\subsubsection{直线}
+
+绘图命令~\verb|draw|~把几个点以直线段连接起来。\MP~中的缺省长度单位是~bp,用户也可以使用\Fref{tab:unit}~中的其它单位。我们还可以定义一个缩放系数,把坐标都转换成此系数的倍数,这样以后想缩放图形时只要改这个系数即可。
+
+注意~\MP~中的变量赋值符号是~\verb|:=|,而~\verb|=|~用于方程式。变量在同一源文件中只须定义一次,其后的图形中都可以使用。
+
+\begin{fdemo}{\includegraphics{examples/line.mps}}
+draw (0,0)--(40,0)--(20,20)--(0,0);
+u:=10pt; %缩放系数
+draw (5u,0)--(9u,0)--(7u,2u)--cycle;
+\end{fdemo}
+
+几段直线或曲线可以构成一条路径(path),在路径末尾加个~\verb|cycle|~就能构成封闭路径(closed path)。上例中的两个三角形看起来都是封闭的,但是前面这个其实不是真正的封闭路径。
+
+\subsection{点和线宽}
+\verb|drawdot|~命令可以在指定坐标画一个点,为了使它醒目些我们可以换支粗一点的画笔。\MP~中的画笔缺省是直径~0.5pt~的圆形,拿它画出来的线宽就是~0.5pt。
+
+\begin{fdemo}{\includegraphics{examples/dot.mps}}
+draw (0,0)--(10u,4u);
+pickup pencircle scaled 2pt;
+drawdot (0,0);
+drawdot (10u,4u);
+\end{fdemo}
+
+上面的~\verb|pickup|~是一种全局操作,也就是说它会影响到之后所有的绘图命令,我们也可以用~\verb|withpen|~为单个绘图命令设置画笔。
+
+\begin{code}
+draw (0,0)--(10u,4u) withpen pencircle scaled 2pt;
+\end{code}
+
+\subsubsection{曲线}
+曲线和直线的命令相近,只是把连接两个点的~\verb|--|~换成了~\verb|..|。如果共用一些坐标,直线和曲线也可以混在一条语句里画。
+
+\begin{fdemo}{\includegraphics{examples/curve.mps}}
+draw (0,.5u)..(5u,3u)..(10u,1.5u)..
+ (7u,0)..(5u,1.5u)..(7u,1.5u);
+\end{fdemo}
+
+\MP~的曲线用三次贝塞尔(Cubic B\'ezier)算法实现。用户可以在命令中增加~direction(方向)、Tension(张力)和~Curl(曲率)等控制,限于篇幅本文不赘述。
+
+\subsubsection{预定义图形}
+~\verb|fullcircle|~命令以原点为圆心画一个单位圆,类似的预定义图形还有~\verb|halfcircle、quartercircle、unitsquare|~等。注意单位正方形的参考点在左下而不在其中心。
+
+通过不同的横向和纵向缩放系数,我们可以把圆形和正方形变成椭圆和长方形。
+
+\begin{code}
+draw fullcircle scaled 2u;
+draw halfcircle scaled 2u shifted (3u,0);
+draw quartercircle scaled 2u shifted (5u,0);
+draw fullcircle xscaled 4u yscaled 2u shifted (9u,0);
+draw unitsquare scaled 2u shifted (12u,-u);
+draw unitsquare xscaled 4u yscaled 2u shifted (15u,-u);
+\end{code}
+
+\begin{out}
+\includegraphics{examples/predefined.mps}
+\end{out}
+
+\subsection{图形控制}
+
+\subsubsection{线型和箭头}
+在绘制图形时,我们不仅可以变换线宽,也可以使用多种线型。
+\begin{code}
+draw (0,0)--(10u,0) dashed withdots;
+draw (0,1u)--(10u,1u) dashed withdots scaled 2;
+draw (0,2u)--(10u,2u) dashed evenly;
+draw (0,3u)--(10u,3u) dashed evenly scaled 2;
+\end{code}
+
+\begin{out}
+\includegraphics{examples/dashed.mps}
+\end{out}
+
+箭头和直线、曲线的语法相近,注意画反向箭头时需要把两个坐标用一对~\verb|()|~括起来。
+
+\begin{fdemo}{\includegraphics{examples/arrow.mps}}
+drawarrow (0,4u)--(9u,4u);
+drawarrow reverse ((0,2u)--(9u,2u));
+drawdblarrow (0,0)--(9u,0);
+\end{fdemo}
+
+\subsubsection{颜色和填充}
+\MP~预定义的颜色有黑、白、红、绿、蓝,它们的~RGB~值分别为(0,0,0)、(1,1,1)、(1,0,0)、(0,1,0)、(0,0,1),缺省色就是黑色。
+
+绘图命令一般都可以通过~\verb|withcolor|~参数来使用各种颜色。封闭路径可以用~\verb|fill|~命令填充。
+
+\begin{fdemo}{\includegraphics{examples/color.mps}}
+draw (0,4u)--(9u,4u) withcolor red;
+draw (0,2u)--(9u,2u) withcolor green;
+draw (0,0)--(9u,0) withcolor blue;
+\end{fdemo}
+
+\begin{code}
+fill p scaled u;
+fill p scaled u shifted (3u,0) withcolor red;
+fill p scaled u shifted (6u,0) withcolor green;
+fill p scaled u shifted (9u,0) withcolor blue;
+\end{code}
+
+\begin{out}
+\includegraphics{examples/fill.mps}
+\end{out}
+
+另一个命令~\verb|filldraw|~可以看作是~\verb|fill+draw|,它除了填充外还会把路径用指定的画笔画一遍。然而不幸的是画边缘和填充内部只能用同一种颜色,所以它的用处不大。
+
+除了为每个绘图命令单独指定颜色,我们也可以使用一个全局命令,使得其后的绘图命令都使用某种颜色。
+\begin{code}
+drawoption(withcolor blue);
+\end{code}
+
+下面的方法可以用来定义基本色以外的颜色,用基本色混色或直接用RGB值效果是一样的。
+
+\begin{code}
+color c[];
+c1 := .9red + .6green + .3blue;
+c2 := (.9,.6,.3);
+\end{code}
+
+\subsubsection{图形变换}
+我们可以对路径进行缩放、平移、旋转等变换操作,横向和纵向缩放可以分开进行。由于旋转是围绕原点进行的,所以要注意平移和旋转的顺序。下例中定义了一个~\verb|path|~变量,以便后面重用。
+
+\begin{code}
+path p;
+p := (0,0)--(2,0)--(1,1.732)--cycle;
+draw p scaled u;
+draw p xscaled 2u yscaled u shifted (3u,0);
+draw p scaled u rotated 60 shifted (8u,0);
+\end{code}
+
+\begin{out}
+\includegraphics{examples/transform.mps}
+\end{out}
+
+\subsubsection{标注}
+\verb|\label|~命令可以在指定的点附近加文字标注。\MP~也可以用一对~\verb|btex|~和~\verb|etex|~来嵌入一些~\TeX~内容,比如数学标注。
+
+\begin{code}
+draw unitsquare xscaled 10u yscaled 4u;
+label.top("top", (5u,4u));
+label.bot("bottom", (5u,0));
+label.lft("left", (0,2u));
+label.rt("right", (10u,2u));
+\end{code}
+\begin{code}
+label.ulft("upper left", (0,4u));
+label.urt("upper right", (10u,4u));
+label.llft("lower left", (0,0));
+label.lrt("lower right", (10u,0));
+label.rt(btex $E=mc^2$ etex, (3u,2u));
+\end{code}
+
+\begin{out}
+\includegraphics{examples/label.mps}
+\end{out}
+
+因为用缺省方法编译生成的~MPS~不嵌入字体,当~\MP~包含文字时,GSview~就不能正常查看。这时我们可以给编译命令加个参数,生成的~MPS~就会包含字体信息。注意这种方法生成的~MPS~虽然~GSview~能查看,\verb|dvipdfmx|~却不能正常处理。
+
+\begin{code}
+mpost \prologues:=2; input fig.mp
+\end{code}
+
+\subsection{编程功能}
+
+\subsubsection{数据类型和变量}
+\MP~中有10~种基本数据类型:numeric、pair、path、pen、~color~、cmykcolor、transform、string、boolean、picture。我们已经接触过其中几种,比如缩放系数~u~就是一个~numeric,一个点的坐标是一个~pair,几个点用直线或曲线连起来是一个~path,pencircle~是一种~pen,black~是一种~color,scaled、rotated、shifted~都是~transform。
+
+numeric~类型变量的精度是~1/65536,它的绝对值不能超过~4096,在计算过程中数值可以达到~32768。这样的规定也应归功于当年的电脑硬件,不过对于科技文档插图而言,4096~一般还是够用的。
+
+除了缺省的~numeric,其它变量在使用之前都需要用数据类型来显式声明。相同类型的变量可以在一行语句中声明,但是带下标的变量不能放在同一行(这个规定很蹊跷)。
+\begin{code}
+numeric x,y,z; %正确
+numeric x1,x2,x3; %错误
+numeric x[]; %正确
+\end{code}
+
+\subsubsection{数学运算}
+\MP~中可以使用普通的运算符,比如~\verb|+ - * /|;也提供一些特殊的运算符,比如~\verb|a++b|~表示$\sqrt{a^2+b^2}$,\verb|a+-+b|~表示$\sqrt{a^2-b^2}$;另外\Fref{tab:math_function}~列出一些常用数学函数。
+
+\begin{table}[htbp]
+\caption{数学函数}
+\label{tab:math_function}
+\centering
+\begin{tabular}{llll}
+ \toprule
+ abs & 绝对值 & mexp & 指数 \\
+ round & 四舍五入 & mlog & 对数 \\
+ ceiling & 向上圆整 & sind & 正弦 \\
+ floor & 向下圆整 & cosd & 余弦 \\
+ mod & 模余 & normaldeviate & 正态分布随机数 \\
+ sqrt & 开方 & uniformdeviate & 均匀分布随机数 \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\subsubsection{循环}
+当执行重复任务时,循环语句可以让程序变得简洁。注意下例中的循环语句是一条命令,之所以分成三行写是为了看起来清晰点。
+
+\begin{fdemo}{\includegraphics{examples/loop.mps}}
+draw (0,0) %注意这里没有分号
+for x=1 upto 3:
+ ..(x*x,x)*u
+endfor;
+\end{fdemo}
+
+循环语句缺省步长是~1,我们也可以改用其它步长。\verb|upto|~其实就是~\verb|step 1 until|~的缩写方式。
+\begin{code}
+for x=1 step .5 until 3:
+\end{code}
+
+\section{PSTricks}
+\label{sec:pstricks}
+
+PSTricks~是一个基于~PS~的宏包,有了它用户就可以直接在~\LaTeX~文档中插入绘图命令。PSTricks~早期的作者是~Timothy Van Zandt\footnote{法国Insead大学经济系教授。},初始开发年月不详,他于~1997~年退居二线,之后由~Denis Girou、Sebastian Rahtz\footnote{牛津大学计算机系网管。}、Herbert Voß~等维护。
+
+本文只介绍~PSTricks~的基本功能,若想深入了解请参阅~Van Zandt~的《PSTricks User's Guide》\citep{Zandt_2007}。另外\Fref{tab:pst_add}~列出了一些可以和~PsTricks~配合使用的辅助宏包。
+
+\begin{table}[htbp]
+\caption{PSTricks~辅助宏包}
+\label{tab:pst_add}
+\centering
+\begin{tabular}{llll}
+ \toprule
+ multido & 循环语句 & pst-eucl & 几何函数 \\
+ pst-plot & 函数绘图 & pst-math & 弧度三角函数 \\
+ pst-plot3d & 三维绘图 & pstricks-add & 极坐标 \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\subsection{准备工作}
+首先要引入~PSTricks~宏包。PSTricks~中缺省长度单位是~1cm,我们也可以设置自己的单位。
+\psset{unit=10pt}
+\begin{code}
+\usepackage{pstricks}
+\psset{unit=10pt}
+\end{code}
+
+绘图命令一般要放在~\verb|pspicture|~环境里,这样~\LaTeX~就会给图形预留一个矩形区域,注意这个矩形要能容纳所有图形对象。为了节省空间,在本节后面的示例代码中,~\verb|pspicture|~环境将被略去。
+
+\begin{code}
+\begin{pspicture}(0,0)(4,2)
+...
+\end{pspicture}
+\end{code}
+
+另外需要注意的是,嵌入~\LaTeX~的~PSTricks~生成的是~PS,\verb|dvips|~可以处理,\verb|dvipdfm|~和pdf\LaTeX~则不能。所以如果使用后两种~driver,需要先行生成~EPS。
+
+第一种方法是把~PSTricks~代码放进一个空白的\LaTeX~页面,用它生成一个简单的~DVI。
+
+\begin{code}
+\documentclass{article}
+\usepackage{pstricks}
+\pagestyle{empty} %页面样式为空
+
+\begin{document}
+\psset{unit=10pt}
+\colorbox{white}{%
+ \begin{pspicture}(0,0)(4,2)%
+ \psdot(0,0)%
+ \psdots(0,2)(2,2)(4,2)%
+ \end{pspicture}%
+}
+\end{document}
+\end{code}
+
+然后用以下命令把~DVI~转为~EPS,\verb|-E|~参数即代表~EPS。上面代码中的~colorbox~使得生成的~EPS~有正确的范围框。
+
+\begin{code}
+dvips pst_dots(.dvi) -E -o dots.eps
+\end{code}
+
+第二种方法是用~\verb|pst-eps|~宏包,它能够在线处理~PSTricks~代码并生成~EPS,这样用户就可以在同一文件中使用该~EPS。
+
+然而~\verb|dvipdfmx|~不能正确处理~\verb|pst-eps|~生成的~EPS。它和~\verb|\rput|、\verb|\uput|~命令,\verb|pst-plot|~宏包中的~\verb|\psaxes|~命令都不兼容。类似的~\verb|ps4pdf|~宏包和~\verb|tabularx|~宏包不兼容。

+\psdot(0,0)
+\psdots(0,2)(2,2)(4,2)
+\end{fdemo}
+
+\subsubsection{直线、多边形、矩形}
+\verb|\psline|~命令把多个点用直线段连接起来,线段之间的连接缺省为尖角,也可以设置圆角。
+\begin{comment}

+\psline(0,0)(2,2)(4,0)
+\psline[linearc=.3](5,0)(7,2)(9,0)
+\end{fdemo}
+
+\verb|\pspolygon|~命令和~\verb|\psline|~类似,但是它会形成封闭路径。
+\begin{comment}
+\PSTtoEPS[bbllx=0,bblly=0,bburx=9,bbury=2,makeeps=all]

+
+矩形用~\verb|\psframe|~命令,其参数就是矩形左下角和右上角的坐标。矩形也可以设置圆角。
+\begin{comment}

+\psframe(0,0)(4,2)
+\psframe[framearc=.3](5,0)(9,2)
+\end{fdemo}
+
+\subsubsection{圆、椭圆、圆弧、扇形}
+圆形用~\verb|\pscircle|~命令,参数是圆心和半径。椭圆用~\verb|\psellipse|~命令,参数是中心、长径、短径。注意这两个命令的半径参数用不同的括号,可能是作者的笔误。
+\begin{comment}
+\PSTtoEPS[bbllx=0,bblly=0,bburx=7,bbury=2,makeeps=all]

+
+\begin{fdemo}{\includegraphics{examples/pst_circle.eps}}

+\psellipse(5,1)(2,1)
+\end{fdemo}
+
+圆弧用~\verb|\psarc|~命令,其参数是圆心、半径、起止角度,逆时针作图。~\verb|\psarcn|~类似,只是顺时针作图。扇形用~\verb|\pswedge|~命令。
+\begin{comment}
+\PSTtoEPS[bbllx=0,bblly=0,bburx=11,bbury=2,makeeps=all]
+{examples/arc.eps}{

+\psarcn(5,0){2}{120}{0}
+\pswedge(9,0){2}{0}{120}
+\end{fdemo}
+
+\subsubsection{曲线}
+\verb|\pscurve|~命令把一系列点用平滑曲线连接起来;它的变形版本~\verb|\psecurve|~命令不显示曲线的两个端点;另一变形命令~\verb|\psccurve|~则把曲线封闭起来。
+
+参数~\verb|showpoints=true|~用来显示曲线的构成点,此参数也可用于其它绘图命令。
+\begin{comment}
+\PSTtoEPS[bbllx=0,bblly=0,bburx=15,bbury=2,makeeps=all]
+{examples/curve.eps}{

+\end{fdemo}
+
+\subsubsection{网格和坐标}
+科技制图通常会用到坐标网格。\verb|\psgrid|~命令输出一个矩形网格,它有三个参数点。网格坐标标注在通过第一个点的两条直线上,第二和第三个点是矩形的两个对角顶点。当第一个参数省略时,坐标标注在通过第一个顶点的两条矩形边上。
+\begin{comment}

+
+\verb|pst-plot|~宏包提供的~\verb|\psaxes|~命令输出坐标轴。它的参数和~\verb|\psgrid|~的类似,刻度和标注都可以灵活地设置,也可以把坐标轴改成一个矩形框的形式。
+\begin{code}
+\psset{unit=10pt}
+\psaxes{<->}(0,0)(-1,-1)(3,2)

+\subsection{图形控制}
+\subsubsection{线型和箭头}
+PSTricks~中的缺省线宽是~0.8pt,缺省线型是实线。以下参数可以控制单个绘图命令的线宽和线型。
+\begin{comment}

+\end{fdemo}
+
+我们也可以用命令~\verb|\psset|~命令来设置全局参数。
+\begin{code}
+\psset{linewidth=1pt,linestyle=dashed}
+\end{code}
+
+以下参数可以控制绘图命令的箭头。
+\begin{comment}

+\end{fdemo}
+
+\subsubsection{颜色和填充}
+PSTricks~预定义的颜色有~black、darkgray、gray、lightgray、white~等灰度颜色,也有~red、green、blue、cyan、magenta、yellow~等彩色。我们也可以自定义灰度颜色和彩色。
+
+\begin{code}
+\newgray{mygray}{.3}
+\newrgbcolor{mycolor}{.3 .4 .5}
+\end{code}
+
+以下参数可以控制单个绘图命令的颜色,我们也可以用~\verb|\psset|~命令设置全局参数。
+\begin{comment}
+\PSTtoEPS[bbllx=0,bblly=0,bburx=9,bbury=4,makeeps=all]
+{examples/color.eps}{
+ \psline[linecolor=red](0,4)(9,4)

+\psline[linecolor=red](0,4)(9,4)
+\psline[linecolor=green](0,2)(9,2)
+\psline[linecolor=blue](0,0)(9,0)
+\end{fdemo}
+
+以下参数可以控制单个绘图命令的填充模式和填充颜色,注意只有封闭路径才可以填充。

+
+\subsection{对象布局}
+\subsubsection{平移}
+参数~\verb|origin|~可以让一个图形对象平移到指定的坐标点,我们也可以用~\verb|\psset|~命令设置全局平移参数。
+\begin{comment}
+\PSTtoEPS[bbllx=0,bblly=0,bburx=7,bbury=2,makeeps=all]
+{examples/origin.eps}{

+\begin{fdemo}{\includegraphics{examples/pst_origin.eps}}
+\psframe(0,0)(3,2)
+\psframe[origin={4,0}](0,0)(3,2)
+\end{fdemo}
+
+\subsubsection{旋转}
+\verb|\rput|~命令可以对一个图形对象同时进行旋转和平移操作。它有两个参数,第一个是旋转角度,第二个是平移到的坐标点。
+\begin{fdemo}{\includegraphics{examples/pst_rput.eps}}
+\psframe(0,0)(3,2)
+\rput{30}(5,0){\psframe(0,0)(3,2)}
+\end{fdemo}
+
+\subsubsection{文字标注}
+\verb|\rput|~命令还可以在指定的坐标点标注文字,这时它的第一个参数是坐标点相对于标注的位置。其取值可以是纵向的~t、b(上下),或横向的~l、r(左右),也可以是纵向和横向位置的组合。
+\begin{fdemo}{\includegraphics{examples/pst_label.eps}}
+\pspolygon(0,0)(4,0)(2,3)
+\rput[r](0,0){A}
+\rput[l](4,0){B}
+\rput[b](2,3){C}
+\end{fdemo}
+
+\verb|\rput|~生成的标注就在坐标点上,有时会感觉离图形太近。另一个命令~\verb|\uput|~则生成缺省距离指定坐标点~5pt的标注,它的第一个参数是标注相对于坐标点的角度。
+\begin{fdemo}{\includegraphics{examples/pst_uput.eps}}
+\pspolygon(0,0)(4,0)(2,3)
+\uput[l](0,0){A}
+\uput[r](4,0){B}
+\uput[u](2,3){C}
+\end{fdemo}
+
+\verb|\uput|~的角度参数可以是任意角度,也可以是字母,参见。注意~\verb|\uput|~的角度参数和~\verb|\rput|~命令的参考点位置参数的定义几乎正好相反,这也许反映了作者洒脱的风格。
+
+\begin{table}[htbp]

+\section{PGF}
+\label{sec:pgf}
+PGF~和~Beamer~的作者都是~Till Tantau\footnote{德国Lübeck大学计算机研究所教授。}。Tantau~当初开发~Beamer~是为了应付~2003~年他的博士学位论文答辩,之后它在~CTAN~上流行开来。2005~年~PGF~从~Beamer~项目中分离出来,成为一个独立的宏包。
+
+本文只对~PGF~作简单介绍,若想深入了解请参阅~Tantau~的《TikZ and PGF Manual》\citep{Tantau_2008}。
+
+\subsection{准备工作}
+一般人们并不直接使用~PGF~命令,而是通过它前端~TikZ~来调用~PGF。在引用~\verb|tikz|~宏包之前,用户需要设置~PGF~系统~driver。
+\begin{code}
+\def\pgfsysdriver{pgfsys-dvipdfmx.def}
+\usepackage{tikz}
+\end{code}
+
+PGF~的缺省长度单位是~1cm,我们也可以改用其它单位。注意这样预定义的长度单位有时会失效,这可能是~PGF~的~bug。
+\begin{code}
+\pgfsetxvec{\pgfpoint{10pt}{0}}
+\pgfsetyvec{\pgfpoint{0}{10pt}}
+\end{code}
+
+TikZ~提供一个~\verb|tikz|~命令和一个~\verb|tikzpicture|~环境,具体绘图指令可以放在~\verb|tikz|~后面,也可以放在~\verb|tikzpicture|~中间。两种方法效果相同,用户可以任意选择。为了节省空间,本节的示例将省略部分环境代码。
+\begin{code}
+\tikz ... %绘图命令
+\begin{tikzpicture}
+... %绘图命令
+\end{tikzpicture}
+\end{code}
+
+\subsection{基本图形对象}
+\subsubsection{直线、多边形、矩形}
+TikZ~中直线的语法和~\MP~类似,加~\verb|cycle|~参数才能构成真正的封闭路径。
+\begin{fdemo}{
+\begin{tikzpicture}
+\draw (0,0)--(4,0)--(2,2)--(0,0);
+\draw (5,0)--(9,0)--(7,2)--cycle;

+\draw (5,0)--(9,0)--(7,3)--cycle;
+\end{fdemo}

+\end{fdemo}
+
+圆弧和椭圆弧命令如下,圆弧的参数是起始点,起始角度、终止角度、半径;椭圆弧则把半径换成了长径和短径。

+抛物线命令如下,除了起止点还可以指定顶点。
+\begin{fdemo}{
+\begin{tikzpicture}
+\draw (-1,1) parabola bend (0,0) (1.414,2);
+\filldraw (-1,1) circle (.1)
+ (0,0) circle (.1)
+ (1.414,2) circle (.1);
+\end{tikzpicture}
+}
+\draw (-1,1) parabola
+ bend (0,0) (1.414,2);
+\end{fdemo}
+
+\subsection{图形控制}
+\subsubsection{线型和箭头}
+绘图命令可以设置线型和箭头参数。
+\begin{fdemo}{
+\begin{tikzpicture}
+\draw[line width=2pt] (0,3)--(9,3);
+\draw[->] (0,2)--(9,2);
+\draw[<-] (0,1)--(9,1);
+\draw[<->] (0,0)--(9,0);
+\end{tikzpicture}
+}
+\draw[line width=2pt] (0,0)--(9,0);
+\draw[->] (0,1)--(9,1);
+\draw[<-] (0,2)--(9,2);
+\draw[<->] (0,3)--(9,3);
+\end{fdemo}
+
+\subsubsection{颜色、填充、阴影}
+颜色参数的用法如下。PGF~可以使用~\verb|xcolor|~宏包\citep{Kern_2007}中定义的所有颜色。
+\begin{fdemo}{
+\begin{tikzpicture}
+\draw[red] (0,4)--(9,4);
+\draw[green] (0,2)--(9,2);
+\draw[blue] (0,0)--(9,0);
+\end{tikzpicture}
+}
+\draw[red] (0,4)--(9,4);
+\draw[green] (0,2)--(9,2);
+\draw[blue] (0,0)--(9,0);
+\end{fdemo}
+
+封闭路径可以用颜色填充,\verb|\filldraw|~命令可以分别指定边框色和填充色。
+\begin{fdemo}{
+\begin{tikzpicture}
+\fill[red] (1,1) circle (1);
+\filldraw[fill=lightgray,draw=black]
+ (4,1) circle (1);
+\end{tikzpicture}
+}
+\fill[red] (1,1) circle (1);
+\filldraw[fill=lightgray,draw=black]
+ (4,1) circle (1);
+\end{fdemo}
+
+\verb|\shade|~命令可以产生渐变和光影效果,缺省是从上到下,灰色渐变为白色。我们也可以使用其它方向和颜色的渐变。
+\begin{code}
+\shade (0,0) rectangle (2,2);
+\shade[left color=red,right color=orange] (3,0) rectangle (5,2);
+\shade[inner color=red,outer color=orange] (6,0) rectangle (8,2);
+\shade[ball color=blue] (10,1) circle (1);
+\end{code}
+
+\begin{out}
+\begin{tikzpicture}
+\shade (0,0) rectangle (2,2);
+\shade[left color=red,right color=orange] (3,0) rectangle (5,2);
+\shade[inner color=red,outer color=orange] (6,0) rectangle (8,2);
+\shade[ball color=blue] (10,1) circle (1);
+\end{tikzpicture}
+\end{out}
+
+\subsubsection{图形变换}
+对图形对象可以进行平移和旋转操作,注意如果两种操作同时进行,它们是有顺序的。注意预定义的长度单位在这里对平移参数失效。
+\begin{code}
+\draw (0,0) rectangle (2,2);
+\draw[xshift=30pt] (0,0) rectangle (2,2);
+\draw[xshift=75pt,rotate=45] (0,0) rectangle (2,2);
+\end{code}
+
+\begin{out}
+\begin{tikzpicture}
+\draw (0,0) rectangle (2,2);
+\draw[xshift=30pt] (0,0) rectangle (2,2);
+\draw[xshift=75pt,rotate=45] (0,0) rectangle (2,2);
+\end{tikzpicture}
+\end{out}
+
+\subsection{样式}
+PGF~比~\MP~和~PSTricks~多了一个有趣的概念:样式(style),它的思路和~HTML~的~CSS~相近。我们可以先定义两种样式,
+\tikzset{
+ myline/.style={line width=2pt},
+ myblueline/.style={myline,blue}
+}
+\begin{code}
+\tikzset{
+ myline/.style={line width=2pt},
+ myblueline/.style={myline,blue}
+}
+\end{code}
+
+然后就可以在绘图命令中这样使用样式。
+\begin{fdemo}{
+\begin{tikzpicture}
+\draw[myline] (0,2)--(9,2);
+\draw[myblueline] (0,0)--(9,0);
+\end{tikzpicture}
+}
+\draw[myline] (0,2)--(9,2);
+\draw[myblueline] (0,0)--(9,0);
+\end{fdemo}
+
+除了用~\verb|\tikzset|~命令定义样式,我们也可以在~\verb|tikzpicture|~环境头部声明样式。前者是全局性的,后者则是局部性的。
+\begin{code}
+\begin{tikzpicture}[
+ thickline/.style=2pt,
+ bluethickline/.style={thickline,color=blue}
+]
+...
+\end{tikzpicture}
+\end{code}
+
+注意在样式中预定义长度单位有时会失效,所以最好使用绝对单位。
+
+\subsection{流程图}
+\subsubsection{节点}
+PGF~中的节点(node)可以是简单的标签,也可以有各种形状的边框,还可以有各种复杂的属性。比如下例中的节点样式:\verb|box|,它的边框是矩形,有圆角;它有最小宽度、高度、文字和边框的距离,边框和填充颜色等属性。
+
+\begin{code}
+\tikzset{
+ box/.style={rectangle, rounded corners=6pt,
+ minimum width=50pt, minimum height=20pt, inner sep=6pt,
+ draw=gray,thick, fill=lightgray}
+}
+\end{code}
+
+除了上述类别属性,节点还可以有名字、位置等属性。在下例中,我们先画了三个有名字的文本框;然后用箭头把文本框连接起来,注意连接时要引用文本框的名字;接着在箭头上加了标签。
+\begin{code}
+\node[box] (tex) at(0,0) {.tex}; %文本框
+\node[box] (dvi) at(10,0) {.dvi}; %文本框
+\node[box] (pdf) at(20,0) {.pdf}; %文本框
+\draw[->] (tex)--(dvi); %箭头
+\draw[->] (dvi)--(pdf); %箭头
+\node at (5,1) {latex}; %标签
+\node at (15,1) {dvipdfmx}; %标签
+\end{code}
+
+\begin{out}
+\begin{tikzpicture}
+\node[box] (tex) at(0,0) {.tex};
+\node[box] (dvi) at(10,0) {.dvi};
+\node[box] (pdf) at(20,0) {.pdf};
+\draw[->] (tex)--(dvi);
+\draw[->] (dvi)--(pdf);
+\node at (5,1) {latex};
+\node at (15,1) {dvipdfmx};
+\end{tikzpicture}
+\end{out}
+
+在上例中的节点都使用了绝对位置,PGF~中还可以使用更灵活一点的相对位置。比如在下例中,dvi~节点在~tex~节点右边~50pt~处(我们前面定义的基本长度单位是~10pt),而~pdf~节点又在~dvi~节点右边~50pt~处。
+
+箭头可以换为专门用来连接节点的~\verb|edge|~;标签也改成相对位置,箭头上方~5pt~处。
+\begin{code}
+\node[box] (tex) {.tex};
+\node[box,right=5 of tex] (dvi) {.dvi};
+\node[box,right=6 of dvi] (pdf) {.pdf};
+\path (tex) edge[->] node[above=.5] {latex} (dvi)
+ (dvi) edge[->] node[above=.5] {dvipdfmx} (pdf);
+\end{code}
+
+\begin{out}
+\begin{tikzpicture}
+\node[box] (tex) {.tex};
+\node[box,right=5 of tex] (dvi) {.dvi};
+\node[box,right=6 of dvi] (pdf) {.pdf};
+\path (tex) edge[->] node[above=.5] {latex} (dvi)
+ (dvi) edge[->] node[above=.5] {dvipdfmx} (pdf);
+\end{tikzpicture}
+\end{out}
+
+\subsubsection{树}
+下面是一棵简单的树。我们可以用一个参数控制相邻节点的距离,预定义长度单位对此参数也会失效。
+\begin{code}
+\begin{tikzpicture}[sibling distance=80pt]
+\node[box] {TeX}
+ child {node[box] {Plain\TeX}}
+ child {node[box] {\LaTeX}
+ child {node[box] {MiKTeX}}
+ child {node[box] {TeX Live}}
+ child {node[box] {MacTeX}}
+ };
+\end{tikzpicture}
+\end{code}
+
+\begin{out}
+\begin{tikzpicture}[sibling distance=80pt]
+\node[box] {TeX}
+ child {node[box] {Plain\TeX}}
+ child {node[box] {\LaTeX}
+ child {node[box] {MiKTeX}}
+ child {node[box] {TeX Live}}
+ child {node[box] {MacTeX}}
+ };
+\end{tikzpicture}
+\end{out}

+\section{字符集和编码}
+\label{sec:encoding}
+
+众所周知电脑内部采用二进制编码,因为它易于用电子电路实现。所有字符(包括字母、数字、符号、控制码等)在电脑内部都是用二进制表示的,字符集(Character Set)的二进制编码被称为字符编码(Character Encoding),有时人们也会混用这两个术语。
+
+1963~年发布的~American Standard Code for Information Interchange(~ASCII)是最早出现的字符编码,它用~7~位(bit)表示了~$2^7=128$个字符,只能勉强覆盖英文字符。
+
+美国人发明了电脑,英语被优先考虑是很自然的事情。随着电脑技术的传播,人们呼吁把字符编码扩充到~8~位也就是一个字节(byte),于是国际标准化组织(International Organization for Standardization,ISO)推出了~ISO 8859。$2^8=256$个字符显然也不能满足需要,所以~8859~被分为十几个部分,从~8859-1(西欧语言)、8859-2(中欧语言),直到~8859-16(东南欧语言),覆盖了大部分使用拉丁字母的语言文字。
+
+在~ISO~标准完全定型之前,IBM~就有一系列自己的字符编码,他们称之为代码页(Code Page),其中著名的有~1981~年就被用于~IBM PC~的~437(扩展~ASCII)、850(西欧语言)、852(东欧语言)。IBM~代码页通常被用于控制台(Console)环境,也就是~MS-DOS~或~Unix Shell~那样的命令行环境。
+
+微软将~IBM~代码页称为~OEM~代码页,自己定义的称为~ANSI~代码页,后者中著名的有1252(西欧语言)、1250(东欧语言)、936(GBK~简体中文)、950(Big5~繁体中文)、932(SJIS~日文)、949(EUC-KR~韩文)等。
+
+1981~年,中国大陆推出了第一个自己的字符集标准~GB2312,它是一个~$94*94$~的表,包括~7445~个字符(含~6763~个汉字)。GB2312~通常采用双字节的EUC-CN编码,所以后者也常常被称为~GB2312~编码;其实~GB2312~还有另一种编码方式~HZ,只是不常用。GB2312~不包含朱镕基的“镕”字,政府、新闻、出版、印刷等行业和部门在使用中感到十分不便,于是它在~1993~年被扩展为~GBK,后者包括~21886~个字符(含~21003~个汉字),没有形成正式标准。2000~年发布的~GB18030~包含~70244~个字符(含~27533~个汉字),采用四字节编码。GB18030~之前还出现过一个~GB13000,没有形成气候。
+
+1990~年ISO~推出了通用字符集(Universal Character Set,UCS),即~ISO 10646,意图一统江湖。它有两种编码:双字节的~UCS-2~和四字节的~UCS-4。
+
+ISO~之外还有个希望一统江湖的组织:统一码联盟(The Unicode Consortium),它于~1991~年推出了~Unicode 1.0。后来两家组织意识到没必要做重复工作,于是开始合并双方的成果,携手奔小康。从~Unicode 2.0~开始,Unicode~采用了与~ISO 10646-1~相同的编码。
+
+Unicode~主要有三种编码:UTF-8、UTF-16、UTF-32。UTF-8~使用一至四个~8~位编码。互联网工程任务组(Internet Engineering Task Force,~IETF)要求所有网络协议都支持~UTF-8,互联网电子邮件联盟(Internet Mail Consortium,IMC)也建议所有电子邮件软件都支持~UTF-8,所以它已成为互联网上的事实标准。UTF-16~用一或两个~16~位编码,基本上是~UCS-2~的超集,和~ASCII~不兼容。UTF-32~用一个~32~位编码,它是~UCS-4~的一个子集。
+
+\section{中文解决方案}
+\TeX~是基于单字节编码的,因为~Knuth~当初开发~\TeX~时没考虑那么远,也没有现成的标准可以借鉴。
+
+\LaTeX~对中文的支持主要有两种方法:张林波\footnote{中科院计算数学所某实验室主任。}开发的~\href{ftp://ftp.cc.ac.cn/pub/cct/}{CCT}~和~Werner Lemberg\footnote{1968~年生于奥地利,从维也纳音乐学院获得作曲、指挥、钢琴、乐团管理、歌手教练等五个专业文凭,后自学中文和数学。曾任职于奥地利和德国多家剧院和乐团,现任德国科布伦茨某剧院指挥。}开发的~CJK~宏包。早期~CCT~比较流行,新的~CCT~也可以和~CJK~配合使用,网上可以找到的最后更新是~2003~年的。CJK~是当前主流,它不仅支持中日韩等东亚文字,还支持几十种其他不同语言的多种编码。
+
+支持简体中文的~\LaTeX~发行版有吴凌云\footnote{中科院应用数学所研究员。}的~CTeX~和李树钧\footnote{德国哈根函授大学研究员。}的~ChinaTeX,繁体中文的有吴聪敏\footnote{台湾大学电机系学士,美国罗彻斯特大学经济学博士,现任台湾大学经济系教授。}、吴聪慧兄弟的~cwTeX~和蔡奇伟\footnote{美国犹他大学计算机博士,现任台湾静宜大学资讯工程系教授。}的~PUTeX。后面两个台湾的发行版包老师不熟悉,前面两个大陆的发行版都包含~MikTeX、CCT、CJK、WinEdt~等。
+
+\section{CJK的使用}
+CJK~的作者写的使用说明比较凌乱和晦涩,读者可以参阅李果正的《我的CJK》\citep{Lee_2004a}。
+
+CJK~有两个基本宏包:\verb|CJK|~和~\verb|CJKutf8|,后者面向~UTF-8~编码。CJK~环境的一般使用方法如下:
+
+\begin{code}
+\usepackage{CJK(utf8)}
+...
+\begin{document}
+\begin{CJK}{<encoding>}{<family>}
+...
+\end{CJK}
+\end{document}
+\end{code}
+
+简体中文常用编码是~GBK~和~UTF8~。family~是指宋体、楷体、隶书等,具体引用要看电脑上安装了什么字体。麻烦的是~GBK~和~UTF8~字体不通用,也就是说每种编码需要自己的字体。CJK~自带的~UTF8~简体字体有~gbsn(宋体)和~gkai(楷体)。CTeX~提供的~GBK~字体有~song(宋体)、fs(仿宋)、kai(楷体)、hei(黑体)、li(隶书)、~you(幼圆)等。
+
+注意使用~\verb|CJKutf8|~宏包时,\verb|CJK|~环境的编码最好是~UTF8,否则可能遭遇不测。
+
+下面是一个简单的~GBK~示例和一个~UTF8~示例,注意用编辑器保存时要选则相应的编码格式,比如前者用~ANSI,后者用~UTF-8。
+\begin{code}
+\documentclass{article}
+\usepackage{CJK}
+\begin{document}
+\begin{CJK}{GBK}{song}
+这是一个CJK例子,使用了GBK编码和song字体。
+\end{CJK}
+\end{document}
+\end{code}
+
+\begin{code}
+\documentclass{article}
+\usepackage{CJKutf8}
+\begin{document}
+\begin{CJK}{UTF8}{gbsn}
+这是一个CJK例子,使用了UTF-8编码和gbsn字体。
+\end{CJK}
+\end{document}
+\end{code}

+\section{历史回顾}
+
+\LaTeX~是一种面向数学和其它科技文档的电子排版系统。一般人们提到的~\LaTeX~是一个总称,它包括~\TeX、\LaTeX、\AmS-\LaTeX~等\footnote{一般认为~\TeX~是一种引擎,\LaTeX~是一种格式,而~\AmS-\LaTeX~等是宏集。此处目的是简介,故不展开讨论。}。
+
+\TeX~的开发始于~1977~年~5~月,Donald E. Knuth\footnote{斯坦福大学计算机系教授,已退休。}开发它的初衷是用于《The Art of Computer Programming》的排版。1962~年~Knuth~开始写一本关于编译器设计的书,原计划是~12~章的单行本。不久~Knuth~觉得此书涉及的领域应该扩大,于是越写越多,如滔滔江水连绵不绝,又如黄河泛滥一发不可收拾。1965~年完成的初稿居然有~3000~页,全是手写的!据出版商估计,这些手稿印刷出来需要~2000~页,出书的计划只好改为七卷,每卷一或两章。1976~年~Knuth~改写第二卷的第二版时,很郁闷地发现第一卷的铅版不见了,而当时电子排版刚刚兴起,质量还差强人意。于是~Knuth~仰天长啸:“我要扼住命运的咽喉”,决定自己开发一个全新的系统,这就是~\TeX。
+
+1978~年~\TeX~第一版发布后好评如潮,Knuth~趁热打铁在~1982~年发布了第二版。人们现在使用的~\TeX~基本就是第二版,中间只有一些小的改进。1990~年~\TeX~ v3.0~发布后,Knuth~宣布除了修正~bug~外停止~\TeX~的开发,因为他要集中精力完成那本巨著的后几卷\footnote{已出版的前三卷是:《Fundamental Algorithms》、《Seminumerical Algorithms》、《Sorting and Searching》;第四卷《Combinatorial Algorithms》和第五卷《Syntactic Algorithms》正在写作中,预计~2015~年出版;第六卷《Theory of Context-free Languages》和第七卷《Compiler Techniques》尚未安排上工作日程。}。此后每发布一个修正版,版本号就增加一位小数,使得它趋近于$\pi$(目前是~3.141592)。Knuth~希望将来他离世时,\TeX~的版本号永远固定下来,从此人们不再改动他的代码。他开发的另一个软件~\MF~也作类似处理,它的版本号趋近于$e$,目前是~2.71828。
+
+\TeX~是一种语言也是一个宏处理器,这使得它很好很强大,但是它同时又很繁琐,让人难以接近。因此~Knuth~提供了一个对~\TeX~进行了封装的宏集~Plain \TeX,里面有一些高级命令,有了它最终用户就无须直接面对枯燥无味的~\TeX。
+
+然而~Plain \TeX~还是不够高级,所以~Leslie Lamport\footnote{现供职于微软研究院。}在~80~年代初期开发了另一个基于~\TeX~的宏集~\LaTeX。1992~年~\LaTeX~ v2.09~发布后,Lamport~退居二线,之后的开发活动由~Frank Mittelbach~领导的~The LaTeX Team~接管。此小组发布的最后版本是~1994~年的~\LaTeXe,他们同时还在进行~\LaTeX~3~的开发,只是正式版看起来遥遥无期。
+
+起初,美国数学学会(American Mathematical Society,AMS)看着\TeX~是好的,就派~Michael Spivak~写了~\AmS-\TeX,这项基于~Plain \TeX~的开发活动进行了两年(1983--1985)。后来与时俱进的~AMS~又看着~\LaTeX~是好的,就想转移阵地,但是他们的字体遇到了麻烦。恰好~Mittelbach~和~Rainer Schöpf(后者也是~LaTeX Team~的成员)刚刚发布了~New Font Selection Scheme for \LaTeX(NFSS),AMS~看着还不错,就拜托他们把~AMSFonts加入~\LaTeX,继而在~1989~年请他们开发~\AmS-\LaTeX。\AmS-\LaTeX~发布于~1990~年,之后它被整合为~\AmS~宏包,像其它宏包一样可以直接运行于~\LaTeX。
+
+\section{优点和缺点}
+当前的文字处理系统大致可以分为两种:标记语言(Markup Language)式的,比如\LaTeX;所见即所得(WYSIWYG)式的,比如~MS Word\footnote{其实~Word~也有自己的标记语言域代码(field code),只是一般用户不了解。}。
+
+一般而言,\LaTeX~相对于所见即所得系统有如下优点:
+\begin{itemize}
+ \item 高质量\ 它制作的版面看起来更专业,数学公式尤其赏心悦目。
+ \item 结构化\ 它的文档结构清晰。
+ \item 批处理\ 它的源文件是文本文件,便于批处理,虽然解释(parse)源文件可能很费劲。
+ \item 跨平台\ 它几乎可以运行于所有电脑硬件和操作系统平台。
+ \item 免费\ 多数~\LaTeX~软件都是免费的,虽然也有一些商业软件。
+\end{itemize}
+
+相应地,\LaTeX~的工作流程、设计原则,资源的缺乏,以及开发人员的历史局限性等种种原因也导致了一些缺陷:
+\begin{itemize}
+ \item 制作过程繁琐,有时需要反复编译,不能直接或实时看到结果。
+ \item 宏包鱼龙混杂,水准参差不齐,风格不够统一。
+ \item 排版风格比较统一,但因而缺乏灵活性。
+ \item 用户支持不够好,文档不完善。
+ \item 对国际语言和字体的支持很差。
+\end{itemize}
+
+抛开~MS Word~不谈,即使跟同为标记语言的~HTML/Web~系统相比,\LaTeX~也有一些不足之处。比如~Web~浏览器对~HTML~内容的渲染(render)比~DVI~浏览器对~\LaTeX~内容的渲染要快上许多,基本上可以算是实时。虽然~HTML~内容可能没有~LaTeX~那么复杂,但是~DVI~毕竟是已经被~\LaTeX~编译过的格式。
+
+还有一点令人困惑的是,有一部分~\LaTeX~阵营的人士习惯于称对方为“邪恶的”或“出卖灵魂的”,如果昂贵的微软系统应当为人诟病,那么更贵的苹果系统为何却被人追捧?
+
+2000~年有记者在采访~Lamport~时问:“为什么当前没有高质量的所见即所得排版系统?”他回答道:“门槛太高了,一个所见即所得系统要做到~\LaTeX~当前的水平,工作量之大不是单枪匹马所能完成\footnote{\TeX/\LaTeX~也不单单是那几个大腕儿完成的,他们背后还有众多默默无闻的小人物,比如当年~Knuth~手下的大批学生。此所谓一将功成万骨枯。}。微软那样的大公司可以做,但是市场太小了。我偶尔也会想加入“Dark Side”,让微软给我一组人马来开发一个这样的系统。”(包老师注:他果然于次年加入微软。)
+
+窃以为这两大阵营其实是萝卜青菜的关系,与其抱残守缺、互相攻讦,不如各取所需;甚至可以捐弃前嫌、取长补短,共建和谐社会。
+
+\section{软件准备}
+\label{sec:latexsoft}
+
+\LaTeX~是一个软件系统,同时也是一套标准。遵照这些标准,实现了(implement)所要求功能的软件集合被称为发行版(distribution)。与此类似的例子有~Java~和~Linux,比如SUN、IBM、BEA~等公司都有自己的~Java~虚拟机(JVM),它们都被称作~Java~的实现;而Linux~有~Red Hat/~Fedora、Ubuntu、SuSE~等众多的发行版。
+
+\begin{table}[htbp]
+\caption{\LaTeX~发行版与编辑器}
+\label{tab:latexsoft}
+\centering
+\begin{tabular}{lll}
+ \toprule
+ 操作系统 & 发行版 & 编辑器 \\
+ \midrule
+ Windows & \href{http://www.miktex.org/}{MikTeX} & \href{http://www.toolscenter.org/}{TeXnicCenter}、\href{http://www.winedt.com/}{WinEdt} \\
+ Unix/Linux & \href{http://www.tug.org/texlive/}{TeX Live} & \href{http://www.gnu.org/software/emacs/emacs.html}{Emacs}、\href{http://vim.sourceforge.net/}{vim}、\href{http://kile.sourceforge.net/}{Kile} \\
+ Mac OS & \href{http://www.tug.org/mactex/}{MacTeX} & \href{http://www.uoregon.edu/~koch/texshop/}{TeXShop} \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\LaTeX~发行版只提供了一个~\LaTeX~后台处理机制,用户还需要一个前台编辑器来编辑它的源文件。常用的~\LaTeX~发行版和编辑器见\fref{tab:latexsoft}。在使用~\LaTeX~的过程中可能还需要其它一些软件,将在后面相关章节中分别介绍。

+
+为了使用~\AmS-\LaTeX~提供的数学功能,我们首先需要在文档的序言部分加载~\verb|amsmath|~宏包,其详细用法可参阅《amsmath User's Guide》\citep{AMS_2002}。更全面的数学内容排版可参阅~George Grätzer\footnote{匈牙利裔,加拿大~Manitoba~大学数学系教授。}的《More Math into \LaTeX, 4th Edition》\citep{Gratzer_2007}。

+
+\section{数学模式}
+\LaTeX~中的数学模式有两种形式:inline~和~display。前者是指在正文插入行间数学公式,后者独立排列,可以有或没有编号。
+
+行间公式用一对~\verb|$...$|~来输入,独立公式用~\verb|equation|~或~\verb|equation*|~环境来输入,有~\verb|*|~的版本不生成公式编号。
+
+前文提到~\verb|\fbox|~命令可以给文本内容加个方框,数学模式下也有类似的命令~\verb|\boxed|。
+
+\begin{demo}
+爱因斯坦的$E=mc^2$方程
+\begin{equation}
+ E=mc^2
+\end{equation}
+\[ E=mc^2 \]
+\[ \boxed{E=mc^2} \]
+\end{demo}
+
+\section{基本原素}
+\subsection{字母}
+
+英文字母在数学模式下可以直接输入,希腊字母则需要用\Fref{tab:greek}~中的命令输入,注意大写希腊字母的命令首字母也是大写。
+
+\begin{table}[htbp]
+\caption{希腊字母}
+\label{tab:greek}
+\centering
+\begin{tabular}{llllllll}
+ \toprule
+ $\alpha$ & \verb|\alpha| & $\theta$ & \verb|\theta| &
+ $o$ & \verb|o| & $\tau$ & \verb|\tau| \\
+ $\beta$ & \verb|\beta| & $\vartheta$ & \verb|\vartheta| &
+ $\pi$ & \verb|\pi| & $\upsilon$ & \verb|\upsilon| \\
+ $\gamma$ & \verb|\gamma| & $\iota$ & \verb|\iota| &
+ $\varpi$ & \verb|\varpi| & $\phi$ & \verb|\phi| \\
+ $\delta$ & \verb|\delta| & $\kappa$ & \verb|\kappa| &
+ $\rho$ & \verb|\rho| & $\varphi$ & \verb|\varphi| \\
+ $\epsilon$ & \verb|\epsilon| & $\lambda$ & \verb|\lambda| &
+ $\varrho$ & \verb|\varrho| & $\chi$ & \verb|\chi| \\
+ $\varepsilon$ & \verb|\varepsilon| & $\mu$ & \verb|\mu| &
+ $\sigma$ & \verb|\sigma| & $\psi$ & \verb|\psi| \\
+ $\zeta$ & \verb|\zeta| & $\nu$ & \verb|\nu| &
+ $\varsigma$ & \verb|\varsigma| & $\omega$ & \verb|\omega| \\
+ $\eta$ & \verb|\eta| & $\xi$ & \verb|\xi| &
+ & & & \\
+ $\Gamma$ & \verb|\Gamma| & $\Lambda$ & \verb|\Lambda| &
+ $\Sigma$ & \verb|\Sigma| & $\Psi$ & \verb|\Psi| \\
+ $\Delta$ & \verb|\Delta| & $\Xi$ & \verb|\Xi| &
+ $\Upsilon$ & \verb|\Upsilon| & $\Omega$ & \verb|\Omega| \\
+ $\Theta$ & \verb|\Theta| & $\Pi$ & \verb|\Pi| &
+ $\Phi$ & \verb|\Phi| & & \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\subsection{指数、下标、根号}
+指数或上标用~\verb|^|~表示,下标用~\verb|_|~表示,根号用~\verb|\sqrt|~表示。上下标如果多于一个字母或符号,需要用一对~\verb|{}|~括起来。
+\begin{demo}
+\[x_{ij}^2\quad \sqrt[2]{x}\]
+\end{demo}
+
+\subsection{分数}
+分数用~\verb|\frac|~命令表示,它会自动调整字号,比如在行间公式中小一点,在独立公式则大一点。\verb|\dfrac|~命令把分数的字号显式设置为独立公式中的大小,\verb|\tfrac|~命令则把字号设为行间公式中的大小。
+\begin{demo}
+$\frac{1}{2} \dfrac{1}{2}$
+\[\frac{1}{2} \tfrac{1}{2}\]
+\end{demo}
+
+\subsection{运算符}
+有些小的运算符(operator)例如~\verb|+ - * /|~等可以直接输入,另一些则需要特殊命令。完整的数学符号参见~Scott Pakin~的《The Comprehensive \LaTeX~ Symbol List》\citep{Pakin_2008}。
+\begin{code}
+\[\pm \times \div \cdot \cap \cup \geq \leq \neq \approx \equiv\]
+\end{code}
+
+\begin{out}
+\[\pm\quad \times\quad \div\quad \cdot\quad \cap\quad \cup\quad \geq\quad \leq\quad \neq\quad \approx\quad \equiv\]
+\end{out}
+
+和、积、极限、积分等大运算符用~\verb|\sum \prod \lim \int|~等表示。它们的上下标在行间公式中被压缩,以适应行高。。
+
+\begin{code}
+$\sum_{i=1}^n i \prod_{i=1}^n \lim_{x\to0}x^2 \int_a^b x^2 dx\$
+\[\sum_{i=1}^n i \prod_{i=1}^n \lim_{x\to0}x^2 \int_a^b x^2 dx\]
+\end{code}
+
+\begin{out}
+$\sum_{i=1}^n i\quad \prod_{i=1}^n\ \lim_{x\to0}x^2\ \int_a^b x^2\mathrm{d}x$
+\[\sum_{i=1}^n i\quad \prod_{i=1}^n\ \lim_{x\to0}x^2\ \int_a^b x^2\mathrm{d}x\]
+\end{out}
+
+多重积分如果用多个~\verb|\int|~来输入的话,积分号间距过宽。正确的方法是用~\verb|\iint \iiint \iiiint \idotsint|~等命令输入。从下例中可以看出两种方法的差异。
+
+\begin{out}
+\[\iint\quad \iiint\quad \iiiint\quad \idotsint\]
+\[\int\int\quad \int\int\int\quad \int\int\int\int\quad \int\dots\int\]
+\end{out}
+
+\subsection{分隔符}
+各种括号用~\verb|() [] \{\} \langle\rangle|~等命令表示,注意花括号通常用来输入命令和环境的参数,所以在数学公式中它们前面要加~\verb|\|。因为~\LaTeX~中的~\verb+|和\|+~的应用过于随意,~amsamth~宏包推荐用~\verb|\lvert\rvert|~和~\verb|\lVert\rVert|~取而代之。
+
+我们可以在上述分隔符前面加~\verb|\big \Big \bigg \Bigg|~等命令来调整大小。\LaTeX~原有的方法是在分隔符前面加~\verb|\left \right|~来自动调整大小,但是效果不佳,所以~amsmath~不推荐用这种方法。
+
+\begin{out}
+\[\Bigg(\bigg(\Big(\big((x+y)\big)\Big)\bigg)\Bigg)\quad
+\Bigg[\bigg[\Big[\big[[x+y]\big]\Big]\bigg]\Bigg]\quad
+\Bigg\{\bigg\{\Big\{\big\{\{x+y\}\big\}\Big\}\bigg\}\Bigg\}\]
+\[\Bigg\langle\bigg\langle\Big\langle\big\langle\langle x+y \rangle\big\rangle\Big\rangle\bigg\rangle\Bigg\rangle\quad
+\Bigg\lvert\bigg\lvert\Big\lvert\big\lvert\lvert x+y \rvert\big\rvert\Big\rvert\bigg\rvert\Bigg\rvert\quad
+\Bigg\lVert\bigg\lVert\Big\lVert\big\lVert\lVert x+y \rVert\big\rVert\Big\rVert\bigg\rVert\Bigg\rVert\]
+\end{out}
+
+\subsection{箭头}
+\Fref{tab:arrow}~列出了部分箭头的输入方法。另外还有两个命令生成的箭头可以根据上下标自动调整长度。
+
+\begin{table}[htbp]
+\caption{箭头}
+\label{tab:arrow}
+\centering
+\begin{tabular}{llll}
+ \toprule
+ $\leftarrow$ & \verb|\leftarrow| & $\longleftarrow$ & \verb|\longleftarrow| \\
+ $\rightarrow$ & \verb|\rightarrow| & $\longrightarrow$ & \verb|\longrightarrow| \\
+ $\leftrightarrow$ & \verb|\leftrightarrow| & $\longleftrightarrow$ & \verb|\longleftrightarrow| \\
+ $\Leftarrow$ & \verb|\Leftarrow| & $\Longleftarrow$ & \verb|\Longleftarrow| \\
+ $\Rightarrow$ & \verb|\Rightarrow| & $\Longrightarrow$ & \verb|\Longrightarrow| \\
+ $\Leftrightarrow$ & \verb|\Leftrightarrow| & $\Longleftrightarrow$ & \verb|\Longleftrightarrow| \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\begin{demo}
+\[\xleftarrow{x+y+z}\quad
+\xrightarrow[x<y]{a*b*c}\]
+\end{demo}
+
+\subsection{标注}
+\Fref{tab:accent}~列出一些短的注音符号(accent),\Fref{tab:notation}~则列出一些长的标注符号。
+
+\begin{table}[htbp]
+\caption{数学注音符号}
+\label{tab:accent}
+\centering
+\begin{tabular}{llllllll}
+ \toprule
+ $\acute{x}$ & \verb|\acute{x}| & $\tilde{x}$ & \verb|\tilde{x}| & $\mathring{x}$ & \verb|\mathring{x}| \\
+ $\grave{x}$ & \verb|\grave{x}| & $\breve{x}$ & \verb|\breve{x}| & $\dot{x}$ & \verb|\dot{x}| \\
+ $\bar{x}$ & \verb|\bar{x}| & $\check{x}$ & \verb|\check{x}| & $\ddot{x}$ & \verb|\ddot{x}| \\
+ $\vec{x}$ & \verb|\vec{x}| & $\hat{x}$ & \verb|\hat{x}| & $\dddot{x}$ & \verb|\dddot{x}| \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\begin{table}[htbp]
+\caption{长标注符号}
+\label{tab:notation}
+\centering
+\begin{tabular}{llll}
+ \toprule
+ $\overline{xxx}$ & \verb|\overline{xxx}| & $\overleftrightarrow{xxx}$ & \verb|\overleftrightarrow{xxx}| \\
+ $\underline{xxx}$ & \verb|\underline{xxx}| & $\underleftrightarrow{xxx}$ & \verb|\underleftrightarrow{xxx}| \\
+ $\overleftarrow{xxx}$ & \verb|\overleftarrow{xxx}| & $\overbrace{xxx}$ & \verb|\overbrace{xxx}| \\
+ $\underleftarrow{xxx}$ & \verb|\underleftarrow{xxx}| & $\underbrace{xxx}$ & \verb|\underbrace{xxx}| \\
+ $\overrightarrow{xxx}$ & \verb|\overrightarrow{xxx}| & $\widetilde{xxx}$ & \verb|\widetilde{xxx}| \\
+ $\underrightarrow{xxx}$ & \verb|\underrightarrow{xxx}| & $\widehat{xxx}$ & \verb|\widehat{xxx}| \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\subsection{省略号}
+省略号用~\verb|\dots \cdots \vdots \ddots|~等命令表示,注意~\verb|\cdots|~和~\verb|\dots|~的差别。
+\begin{out}
+\[\dots\quad \cdots\quad \vdots\quad \ddots\]
+\end{out}
+
+\subsection{空白间距}
+在数学模式中,我们可以用\Fref{tab:quad}中的命令生成不同的间距,注意负间距命令~\verb|\!|~可以用来减小间距。
+
+\begin{table}[htbp]
+\caption{空白间距}
+\label{tab:quad}
+\centering
+\begin{tabular}{llll}
+ \toprule
+ \verb|\,| & 3/18 em & \verb|\quad| & 1 em \\
+ \verb|\:| & 4/18 em & \verb|\qquad| & 2 em \\
+ \verb|\;| & 5/18 em & \verb|\!| & -3/18 em \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\section{矩阵和行列式}
+数学模式下可以用~\verb|array|~环境来生成行列表。参数~\verb|{ccc}|~用于设置每列的对齐方式,\verb|l、c、r|~分别表示左中右;\verb|\\|~和~\verb|&|~用来分隔行和列。
+
+\begin{demo}
+\[\begin{array}{ccc}
+x_1 & x_2 & \dots \\
+x_3 & x_4 & \dots \\
+\vdots & \vdots & \ddots \\
+\end{array}\]
+\end{demo}
+
+\verb|amsmath|~有几个类似的环境:\verb|pmatrix、bmatrix、Bmatrix、vmatrix|~和~
+\verb|Vmatrix|,它们和~\verb|array|~的主要区别是会在表两端加上~$()\; []\; \{\}\; ||\; \|\|$~等分隔符,其次这些环境没有列对齐方式参数。
+
+行间公式可以用~\verb|smallmatrix|~环境来生成排列紧密的小矩阵。
+
+\section{多行公式}
+有时一个公式太长一行放不下,或几个公式需要写成一组,这时我们就要用到~\verb|amsmath|~提供的几个适合多行公式的环境。
+
+\subsection{长公式}
+对于多行不需要对齐的长公式,我们可以用~\verb|multline|~环境。
+\begin{demo}
+\begin{multline}
+x=a+b+c+\\
+d+e+f+g
+\end{multline}
+\end{demo}
+
+需要对齐的长公式可以用~\verb|split|~环境,它本身不能单独使用,因此也称作次环境,必须包含在~\verb|equation|~或其它数学环境内。\verb|split|~环境用~\verb|\\|~和~\verb|&|~来分行和设置对齐位置。
+\begin{demo}
+\[ \begin{split}
+x=&a+b+c+\\
+ &d+e+f+g
+\end{split} \]
+\end{demo}
+
+\subsection{公式组}
+不需要对齐的公式组用~\verb|gather|环境,需要对齐的用~\verb|align|。
+\begin{demo}
+\begin{gather}
+a=b+c+d\\
+x=y+z
+\end{gather}
+\end{demo}
+
+\begin{demo}
+\begin{align}
+a&=b+c+d\\
+x&=y+z
+\end{align}
+\end{demo}
+
+\verb|multline、gather、align|~等环境都有带~\verb|*|~的版本,它们不生成公式编号。
+
+有多种条件的公式组用~\verb|cases|~次环境。
+\begin{demo}
+\[ y=\begin{cases}
+-x & x<0\\
+x & x\geq0
+\end{cases} \]
+\end{demo}
+
+\section{定理和证明}
+\LaTeX~提供了一个~\verb|\newtheorem|~命令来定义定理之类的环境,其语法如下。
+\begin{code}
+\newtheorem{环境名}[编号延续]{显示名}[编号层次]
+\end{code}
+
+在下例中,我们定义了四个环境:定义、定理、引理和推论,它们都在一个~\verb|section|~内编号,而引理和推论会延续定理的编号。
+\begin{code}
+\newtheorem{defination}{定义}[section]
+\newtheorem{theorem}{定理}[section]
+\newtheorem{lemma}[theorem]{引理}
+\newtheorem{corollary}[theorem]{推论}
+\end{code}
+
+\newtheorem{defination}{定义}[section]
+\newtheorem{theorem}{定理}[section]
+\newtheorem{lemma}[theorem]{引理}
+\newtheorem{corollary}[theorem]{推论}
+
+定义了上述环境之后,我们就可以象下面这样使用它们。
+\begin{demo}
+\begin{defination}
+Java是一种跨平台的编程语言。
+\end{defination}
+\end{demo}
+
+\begin{demo}
+\begin{theorem}
+咖啡因会使人的大脑兴奋。
+\end{theorem}
+\end{demo}
+
+\begin{demo}
+\begin{lemma}
+茶和咖啡都会使人兴奋。
+\end{lemma}
+\end{demo}
+
+\begin{demo}
+\begin{corollary}
+晚上喝咖啡会导致失眠。
+\end{corollary}
+\end{demo}
+
+\verb|proof|环境可以用来输入下面这样的证明,它会在证明结尾输入一个~QED~符号\footnote{拉丁语~quod erat demonstrandum~的缩写。}。
+
+\begin{demo}
+\begin{proof}[命题``物质无限可分''的证明]
+一尺之棰,日取其半,万世不竭。
+\end{proof}
+\end{demo}
+
+\section{数学字体}
+和文本模式类似,数学模式下可以用\Fref{tab:math_font}~中的命令选择不同字体,其中有些字体需要加载~\verb|amsfonts|~宏包。
+
+\begin{table}[htbp]
+\caption{数学字体}
+\label{tab:math_font}
+\centering
+\begin{tabular}{ccccccc}
+ \toprule
+ 缺省 & \verb|\mathbf| & \verb|\mathit| & \verb|\mathsf| &
+ \verb|\mathcal| & \verb|\mathbb| \\
+ XNZRC & $\mathbf{XNZRC}$ & $\mathit{XNZRC}$ & $\mathsf{XNZRC}$ &
+ $\mathcal{XNZRC}$ & $\mathbb{XNZRC}$ \\
+ \bottomrule
+\end{tabular}
+\end{table}

+\section{超链接}
+\label{sec:hyperlink}
+
+\verb|hyperref|~宏包\citep{Rahtz_2006}提供了一些超链接功能。它给文档内部的交叉引用和参考文献自动加上了超链接,还提供了几个命令。
+
+\verb|\hyperref|~命令对已经定义的label进行简单包装,加上文字描述。
+
+\begin{code}
+\usepackage{hyperref}
+...
+\label{sec:hyperlink}
+...
+例如\ref{sec:hyperlink}是编号形式的链接,而\hyperref[sec:hyperlink]{这个链接}是文字形式的链接,都指向本节开始。
+\end{code}
+
+\begin{out}
+例如\ref{sec:hyperlink}是编号形式的超链接,而\hyperref[sec:hyperlink]{这个链接}则是文字形式,都指向本节开始。
+\end{out}
+
+\verb|\url|~和~\verb|\href|~命令可以用来定义外部链接,后者有文字描述。
+
+\begin{code}
+\url{http://www.dralpha.com/}
+\href{http://www.dralpha.com/}{包老师的主页}
+\end{code}
+
+\begin{out}
+\url{http://www.dralpha.com/}
+
+\href{http://www.dralpha.com/}{包老师的主页}
+\end{out}
+
+%hyperref选项
+
+\section{长文档}
+当文档很长时,我们可以把它分为多个文件,然后在主控文档的正文中引用它们。注意~\verb|\include|~命令会新起一页,如果不想要新页可以改用~\verb|\input|~命令。
+\begin{code}
+%master.tex
+\begin{document}
+\include{chapter1.tex}
+\include{chapter2.tex}
+...
+\end{document}
+\end{code}
+
+当文档很长时,编译一遍也会很花时间,我们可以用~\verb|syntonly|~宏包。这样编译时就只检查语法,而不生成结果文件。
+\begin{code}
+\usepackage{syntonly}
+...
+\syntaxonly
+\end{code}
+
+\section{参考文献}
+在文档中,我们经常要引用参考文献(bibliography)。\LaTeX~提供的~\verb|thebibliography|~环境和~\verb|\bibtem|~命令可以用来定义参考文献条目及其列表显示格式,\verb|cite|~命令用来在正文中引用参考文献条目。这种方法把内容和格式混在一起,用户需要为每个条目设置格式,很繁琐且易出错。
+
+\subsection{BibTeX}
+1985年,~Oren Patashnik\footnote{Wiki~上说他是~Knuth~的学生,我发现他不在~Knuth~的博士生列表上,而在姚期智的博士生列表上,也许他是~Knuth~的硕士生。}和~Lamport~开发了~\BibTeX\citep{Patashnik_1988},其详细使用方法请参阅~Nicolas Markey~的《Tame the BeaST: The B to X of BibTeX》\citep{Markey_2005}
+
+\BibTeX~把参考文献的数据放在一个~\verb|.bib|~文件中,显示格式放在~\verb|.bst|~文件中。普通用户一般不需要改动~\verb|.bst|,只须维护~\verb|.bib|~数据库。
+
+一个~\verb|.bib|~文件可以包含多个参考文献条目(entry),每个条目有类型、关键字,以及题目、作者、年份等字段。常用条目类型有~article、~book、conference、manual、misc、techreport~等。每种类型都有一些自己的规定字段和可选字段,字段之间用逗号分开。数据库中每个条目的关键字要保持唯一,因为引用时要用到它们。
+
+下例显示了一个条目,它的类型是~\verb|manual|,关键字是~\verb|Markey_2005|。~\verb|.bib|~文件可以用普通文本编辑器来编辑,也可以用专门的文献管理软件来提高效率。包老师推荐~\href{http://jabref.sourceforge.net/}{JabRef}。
+
+\begin{code}
+@MANUAL{Markey_2005,
+ title = {Tame the BeaST: The B to X of BibTeX},
+ author = {Nicolas Markey},
+ year = {2005},
+ url = {http://www.ctan.org/tex-archive/info/bibtex/
+ tamethebeast/}
+}
+\end{code}
+
+有了数据库,我们可以象下面这样引用一个条目。
+\begin{demo}
+请参阅\cite{Markey_2005}。
+\end{demo}
+
+前文中我们提到含有交叉引用的文档需要编译两遍。含有参考文献的文档更麻烦,它需要依次执行~\verb|latex、bibtex、latex、latex|~等四次编译操作。
+
+\begin{enumerate}
+ \item 第一遍~\verb|latex|~只把条目的关键字写到中间文件~\verb|.aux|~中去。
+ \item \verb|bibtex|~根据\verb|.aux、.bib、.bst|~生成一个~\verb|.bbl|~文件,即参考文献列表。它的内容就是~\verb|thebibliography|~环境和一些~\verb|\bibtem|~命令。
+ \item 第二遍~\verb|latex|~把交叉引用写到~\verb|.aux|~中去。
+ \item 第三遍~\verb|latex|~则在正文中正确地显示引用。
+\end{enumerate}
+

+\end{tikzpicture}
+\caption{\BibTeX~的编译}
+\label{fig:bibtex}
+\end{figure}
+
+注意在长文档中使用参考文献时,应该用~\verb|latex|~编译主控文档,而用~\verb|bibtex|~编译子文档。
+
+\begin{code}
+latex master(.tex)
+bibtex chapter1(.tex)
+latex master(.tex)
+latex master(.tex)
+\end{code}
+
+\subsection{natbib}
+参考文献的引用通常有两种样式:作者-年份和数字。\LaTeX~本身只支持数字样式,而~\verb|natbib|~宏包\citep{Daly_2007}则同时支持这两种样式。
+
+使用~\verb|natbib|~宏包时,我们首先要引用宏包;其次设置文献列表样式和引用样式,每种列表样式都有自己的缺省引用样式,所以后者可选;然后指定参考文献数据库。
+\begin{code}
+\usepackage{natbib}
+...
+\begin{document}
+\bibliographystyle{plainnat}
+\setcitestyle{square,aysep={},yysep={;}}
+\bibliography{mybib.bib}
+...
+\end{document}
+\end{code}
+
+\verb|natbib|~提供了三种列表样式:plainnat、abbrvnat、unsrtnat。前两种都是作者-年份样式,文献列表按作者-年份排序,后者会使用一些缩写(比如作者的~first name);unsrtnat~是数字样式,文献列表按引用顺序排序。
+
+\verb|\setcitestyle|~命令可以用来改变引用样式的设置,其选项见~\Fref{tab:citestyle}。
+
+\begin{table}[htbp]
+\caption{参考文献引用样式选项}
+\label{tab:citestyle}
+\centering
+\begin{tabular}{ll}
+ \toprule
+ 引用模式 & authoryear、numbers、super \\
+ 括号 & round、square、open={char},close={char} \\
+ 引用条目分隔符 & 分号、逗号、citesep={char} \\
+ 作者年份分隔符 & aysep={char} \\
+ 共同作者年份分隔符 & yysep={char} \\
+ 注解分隔符 & notesep={text} \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+注意在长文档中,每个含参考文献的子文档都需要分别设置列表样式,并指定数据库。
+
+\verb|natbib|~提供了多种引用命令,其中最基本的是~\verb|\citet|~和~\verb|\citep|~,它们在不同引用模式下效果不同。一般不推荐使用~\LaTeX~本身提供的~\verb|\cite|,因为它在作者-年份模式下和~\verb|\citet|~一样,在数字模式下和~\verb|\citep|~一样。
+
+作者-年份模式下引用命令的效果如下。
+\setcitestyle{authoryear}
+\begin{demo}
+参阅\cite{Daly_2007}\\
+参阅\citet{Daly_2007}\\
+参阅\citep{Daly_2007}
+\end{demo}
+
+数字模式下引用命令的效果如下。
+\setcitestyle{numbers}
+\begin{demo}
+参阅\cite{Daly_2007}\\
+参阅\citet{Daly_2007}\\
+参阅\citep{Daly_2007}
+\end{demo}
+
+上标模式下引用命令的效果如下。
+\setcitestyle{super}
+\begin{demo}
+参阅\cite{Daly_2007}\\
+参阅\citet{Daly_2007}\\
+参阅\citep{Daly_2007}
+\end{demo}
+
+另外还有一些引用命令,如~\verb|\citetext、\citenum、\citeauthor|、~\verb|\citeyear|~等,此处不赘述。
+
+\section{索引}
+\verb|makeidx|~宏包提供了索引功能。应用它时,我们首先需要在文档序言部分引用宏包,并使用~\verb|makeindex|~命令;其次在正文中需要索引的地方定义索引,注意索引关键字在全文中须保持唯一;最后在合适的地方(一般是文档末尾)打印索引。
+
+\begin{code}
+\usepackage{makeidx}
+\makeindex
+...
+\begin{document}
+\index{索引关键字}
+...
+\printindex
+\end{document}
+\end{code}
+
+当编译含索引的文档时,用户需要执行~\verb|latex、makeindex、latex|~等三次编译操作。
+
+\begin{enumerate}
+ \item 第一遍~\verb|latex|~把索引条目写到一个~\verb|.idx|~文件中去。
+ \item \verb|makeindex|~把~\verb|.idx|~排序后写到一个~\verb|.ind|~文件中去。
+ \item 第二遍~\verb|latex|~在~\verb|\printindex|~命令的地方引用~\verb|.ind|~的内容,生成正确的DVI。
+\end{enumerate}
+
+\begin{figure}[htbp]
+\centering
+\begin{tikzpicture}
+ \node[box] (tex) {.tex};
+ \node[box, right=4 of tex] (idx) {.idx};
+ \node[box, right=7 of idx] (ind) {.ind};
+ \node[box, right=6 of ind] (dvi) {.dvi};
+ \node[box, above=1.5 of ind] (tex1) {.tex};
+ \node[right=1 of ind] (point) {};
+ \path (tex) edge [arrow] node[auto] {latex} (idx)
+ (idx) edge [arrow] node[auto] {makeindex} (ind)
+ (ind) edge [arrow] node[auto] {latex} (dvi)
+ (tex1.east) edge [rloop] (point);
+\end{tikzpicture}
+\caption{索引的编译}
+\label{fig:makeidx}
+\end{figure}
+
+\section{页面布局}
+在~\LaTeX~中用户可以通过~\verb|\pagestyle|~和~\verb|\pagenumbering|~命令来设置页眉(header)、页脚(footer)的样式和内容。页面样式有以下四种。
+
+\begin{table}[htbp]
+\caption{\LaTeX~页面样式}
+\centering
+\begin{tabular}{ll}
+ \toprule
+ \texttt{empty} & 页眉、页脚空白 \\
+ \texttt{plain} & 页眉空白,页脚含居中页码 \\
+ \texttt{headings} & 页脚空白,页眉含章节名和页码 \\
+ \texttt{myheadings} & 页脚空白,页眉含页码和用户自定义信息 \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\verb|fancyhdr|\citep{Oostrum_2004}宏包提供了更灵活的控制。我们可以用以下代码定制页眉、页脚的内容,以及页眉下方、页脚上方的横线。
+
+\begin{code}
+\usepackage{fancyhdr}
+...
+\pagestyle{fancy} %fancyhdr宏包新增的页面风格
+\lhead{左擎苍}
+\chead{三个代表}
+\rhead{右牵黄}
+\lfoot{左青龙}
+\cfoot{八荣八耻}
+\rfoot{右白虎}
+\renewcommand{\headrulewidth}{0.4pt}
+\renewcommand{\footrulewidth}{0.4pt}
+\end{code}
+
+\ \\
+\begin{tikzpicture}
+\draw (0,0) rectangle (36,10);
+\node at(2,9) {左擎苍};
+\node at(18,9) {三个代表};
+\node at(34,9) {右牵黄};
+\draw (.5,8)--(35.5,8);
+\node at(18,5) {和谐社会};
+\draw (.5,2)--(35.5,2);
+\node at(2,1) {左青龙};
+\node at(18,1) {八荣八耻};
+\node at(34,1) {右白虎};
+\end{tikzpicture}
+
+用户可以在页眉、页脚中使用一些~\LaTeX~变量,比如分别代表页码和章节编号的~\verb|\thepage、\thechapter、\thesection|;代表章节起始单词(Chapter、Section等)的~\verb|\chaptername、\sectionname|~等。
+
+这些变量组合起来可以构成复合标记~\verb|\leftmark|~和~\verb|\rightmark|~。当文档奇偶页面布局不同时,我们可以使用以下方法为奇偶页分别设置页眉、页脚。\verb|fancyhdr|~宏包会自动把每章起始页的样式设为~\verb|plain|,若想去掉页脚中间的页码,可以重定义~\verb|plain|~样式。
+
+\begin{code}
+\pagestyle{fancy}
+\fancyhf{} %清空页眉页脚
+\fancyhead[LE,RO]{\thepage} %偶数页左,奇数页右
+\fancyhead[RE]{\leftmark} %偶数页右
+\fancyhead[LO]{\rightmark} %奇数页左
+\fancypagestyle{plain}{ %重定义plain页面样式
+ \fancyhf{}
+ \renewcommand{\headrulewidth}{0pt}
+}
+\end{code}
+
+\ \\
+\begin{tikzpicture}
+\draw (0,0) rectangle (36,10);
+\node at(2.5,9) {3.2 节名};
+\node at(35,9) {17};
+\draw (.5,8)--(35.5,8);
+\node at(18,5) {奇数页};
+\end{tikzpicture}
+
+\ \\
+\begin{tikzpicture}
+\draw (0,0) rectangle (36,10);
+\node at(1,9) {18};
+\node at(32,9) {Chapter 3 章名};
+\draw (.5,8)--(35.5,8);
+\node at(18,5) {偶数页};
+\end{tikzpicture}
+
+Lamport当初设计~\LaTeX~时把页面布局变量的定义方式搞得比较晦涩,用户在重定义~\verb|\leftmark|~和~\verb|\rightmark|~时,不能直接用~\verb|\renewcommand|~的方法,而要用另外两个命令。
+
+\begin{code}
+\markboth{main-mark}{sub-mark}
+\markright{sub-mark}
+\end{code}
+
+\verb|\leftmark|~即~main-mark,是一种高层次标记,在~article~文档类中它包含~section~的信息,在~report~和~book~则包含~chapter~的信息;\verb|rightmark|~则是一种低层次标记,在~article~中包含~subsection~信息,在~report~和~book~中包含~section~信息。
+
+比如在~\verb|book|~文档类中,章节标记是通过下面的方法定义的,其中的~\verb|#1|~指的是章节的名字。
+
+\begin{code}
+\renewcommand\chaptermark[1]{\markboth{\chaptername \thechapter.
+ #1}{}}
+\renewcommand\sectionmark[1]{\markright{\thesection. #1}}
+\end{code}

+\chapter{跋}
+
+首先向一路披荆斩棘看到这里的读者表示祝贺,至少在精神上你已经成为一名合格的~\LaTeX{}er。从此你生是~\LaTeX~的人,死是~\LaTeX~的鬼。Once Black, never back。没有坚持到这里的同学自然已经重新投向“邪恶”的~MS Word,毕竟那里点个按钮就可以插入图形,点个下拉框就可以选择字体。
+
+当然~\LaTeX{}er也有简单的出路,就是只使用缺省设置,尽量少用插图;不必理会点阵、矢量,也不必理会~Type 1、Type 3、TrueType、OpenType。因为内容高于形式,你把文章的版面、字体搞得再漂亮,它也不会因此成为《红楼梦》;而《红楼梦》即使是手抄本,也依然是不朽的名著。
+
+包老师曾经以为~\LaTeX~和~Word~的关系就好像是《笑傲江湖》中华山的气宗和剑宗,头十年剑宗进步快,中间十年打个平手,再往后气宗就遥遥领先。至于令狐冲的无招胜有招,风清扬的神龙见首不见尾又是另一重境界,普通人恐怕只能望其颈背。
+
+费尽九牛二虎之力熬到本文杀青的时候,才发现从前的想法很傻很天真。让我们挥一挥衣袖,不带走一片云,卧薪尝胆忍辱负重,耐心等待~\XeTeX~和~Lua\TeX。 \ No newline at end of file

+\chapter{序}
+
+\begin{quotation}
+满纸荒唐言,一把辛酸泪!都云作者痴,谁解其中味?\footnote{当年作博士论文时虽不曾增删五次披阅十载,也被折磨得欲仙欲死,故与室友戏言将此五绝加入序言。多年以后的今天终于实现了此夙愿。}
+\begin{flushright}
+--- 曹雪芹
+\end{flushright}
+\end{quotation}
+
+最早听说~\LaTeX~大约是~2002~年,一位同事演示了用它排版的一篇文章和几幅图。包老师\footnote{吾有多重人格,比如本色的是阿黄,下围棋的是隐忍灰衣人,道貌岸然的是包老师。}不以为然,因为那些东西用~Microsoft Word~和~Visio~也可以做到,而且可以做得更快。再次听说它是王垠同学在闹退学,传说他玩~Linux~和~\LaTeX~而走火入魔。
+
+大约是~2005~年底,看了一下~lshort,用~\LaTeX~记了些数学笔记,开始有点感觉。包老师生性愚钝,所以喜欢相对简单的东西。HTML、Java~都用手写,FrontPage、Dreamweaver、JBuilder~之类笨重的家伙看两眼就扔了,所以喜欢上~\LaTeX~只是时间问题。
+
+次年老妻要写博士论文,拿出~Word~底稿让我排版。大家都知道~Word~太简单了,谁都能用,但是不是谁都能用好。人称电脑杀手的老妻制作的~Word~文档自然使出了各种奇门遁甲,加上她实验室、学校和家里电脑里的三个~EndNote~版本互不兼容,实在难以驯服。我只好重起炉灶,拿她的博士论文当小白鼠,试验一下~\LaTeX~的威力。
+
+就这样接触了两三年,总算略窥门径,感觉~\LaTeX~实在是博大精深,浩如烟海。而人到中年大脑储存空间和处理能力都有点捉襟见肘,故时常作些笔记。一来对常用资料和问题进行汇编索引,便于查询;二来也记录一些心得。
+
+日前老妻吵着要学~\LaTeX,便想这份笔记对初学者或有些许借鉴意义,于是系统地整理了一番,添油加醋包装上市。
+
+原本打算分九章,以纪念《九章算术》,实际上第八章完成时已如强弩之末,最后一章还须另择黄道吉日。
+
+本文第一章谈谈历史背景;第二章介绍入门基础;第三至五章讲解数学、插图、表格等对象的用法;第六章是一些特殊功能;第七、八章讨论中文和字体的处理;第九章附加定制内容。
+
+从难易程度上看前两章较简单,插图、字体两章较难。一般认为~\LaTeX~相对于微软的傻瓜型软件比较难学,所以这里采取循序渐进,温水煮青蛙的方法。
+
+初则示弱,麻痹读者;再则巧言令色,请君入瓮;三则舌绽莲花,诱敌深入;彼入得罄中则摧动机关,关门打狗;继而严刑拷打,痛加折磨;待其意乱情迷彷徨无计之时,给予当头棒喝醍醐灌顶,虽戛然而止亦余音绕梁。
+
+鄙人才疏学浅功力不逮,面对汗牛充栋罄竹难书\footnote{此处用法循阿扁古例。}的资料,未免考虑不周挂一漏万,或有误导,敬请海涵。若有高手高手高高手略拨闲暇指点一二,在下感激不尽\footnote{\href{mailto:huang.xingang@gmail.com}{huang.xingang@gmail.com}}
+。
+
+借此感谢一下老妻,如果不是伊天天看韩剧,包老师也不会有时间灌水和整理这份笔记。

+和针对插图的~\verb|figure|~环境类似,\LaTeX~还有另一个针对表格的浮动环境~\verb|table|。我们可以用它给上面的示例穿件马甲,顺便把表格简化为科技文献中常用的三线表。
+
+\begin{code}
+\begin{table}[htbp]
+\caption{浮动环境中的三线表}
+\label{tab:threesome}
+\centering
+\begin{tabular}{lll}
+ \hline
+ 操作系统 & 发行版 & 编辑器 \\
+ \hline
+ Windows & MikTeX & TeXnicCenter \\
+ Unix/Linux & TeX Live & Emacs \\
+ Mac OS & MacTeX & TeXShop \\
+ \hline
+\end{tabular}
+\end{table}
+\end{code}
+
+\begin{table}[htbp]

+ Windows & MikTeX & TeXnicCenter \\
+ Unix/Linux & TeX Live & Emacs \\
+ Mac OS & MacTeX & TeXShop \\
+ \hline
+\end{tabular}
+\end{table}
+
+完美主义者可能觉得上面示例中的三条线一样粗不够美观,这时可以使用~\verb|booktabs|~宏包\citep{Fear_2005}的几个命令。
+
+\begin{code}
+\begin{table}[htbp]
+\caption{浮动环境中的三线表}
+\centering
+\begin{tabular}{lll}
+ \toprule
+ 操作系统 & 发行版 & 编辑器 \\
+ \midrule
+ Windows & MikTeX & TeXnicCenter \\
+ Unix/Linux & TeX Live & Emacs \\
+\end{code}
+
+\begin{code}
+ Mac OS & MacTeX & TeXShop \\
+ \bottomrule
+\end{tabular}
+\end{table}
+\end{code}
+
+\begin{table}[htbp]
+\caption{\texttt{booktabs}~宏包的效果}
+\centering
+\begin{tabular}{lll}
+ \toprule
+ 操作系统 & 发行版 & 编辑器 \\
+ \midrule
+ Windows & MikTeX & TeXnicCenter \\
+ Unix/Linux & TeX Live & Emacs \\
+ Mac OS & MacTeX & TeXShop \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\section{表格宽度}
+有时我们需要控制某栏位宽度,可以将其对齐方式参数从~\verb|l、c、r|~改为~\verb|p{宽度}|~。
+\begin{code}
+\begin{table}[htbp]
+\caption{控制栏位宽度}
+\centering
+\begin{tabular}{p{100pt}p{100pt}p{100pt}}
+ \toprule
+ 操作系统 & 发行版 & 编辑器 \\
+ \midrule
+ Windows & MikTeX & TeXnicCenter \\
+ Unix/Linux & TeX Live & Emacs \\
+ Mac OS & MacTeX & TeXShop \\
+ \bottomrule
+\end{tabular}
+\end{table}
+\end{code}
+
+\begin{table}[htbp]
+\caption{控制栏位宽度}
+\centering
+\begin{tabular}{p{100pt}p{100pt}p{100pt}}
+ \toprule
+ 操作系统 & 发行版 & 编辑器 \\
+ \midrule
+ Windows & MikTeX & TeXnicCenter \\
+ Unix/Linux & TeX Live & Emacs \\
+ Mac OS & MacTeX & TeXShop \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+若想控制整个表格的宽度可以使用~\verb|tabularx|~宏包,\verb|X|~参数表示某栏可以折行。
+
+\begin{code}
+\begin{table}[htbp]
+\caption{控制表格宽度}
+\centering
+\begin{tabularx}{350pt}{lXlX}
+ \toprule
+ 李白 & 平林漠漠烟如织,寒山一带伤心碧。暝色入高楼,有人楼上愁。玉梯空伫立,宿鸟归飞急。何处是归程,长亭更短亭。&
+ 泰戈尔 & 夏天的飞鸟,飞到我的窗前唱歌,又飞去了。秋天的黄叶,它们没有什么可唱,只叹息一声,飞落在那里。\\
+ \bottomrule
+\end{tabularx}
+\end{table}
+\end{code}
+
+\begin{table}[htbp]
+\caption{控制表格宽度}
+\centering
+\begin{tabularx}{350pt}{lXlX}
+ \toprule
+ 李白 & 平林漠漠烟如织,寒山一带伤心碧。暝色入高楼,有人楼上愁。玉阶空伫立,宿鸟归飞急。何处是归程,长亭更短亭。&
+ 泰戈尔 & 夏天的飞鸟,飞到我的窗前唱歌,又飞去了。秋天的黄叶,它们没有什么可唱,只叹息一声,飞落在那里。\\
+ \bottomrule
+\end{tabularx}
+\end{table}
+
+\section{跨行、跨列表格}
+有时某栏需要横跨几列,我们可以使用~\verb|\multicolumn|~命令。它的前两个参数指定横跨列数和对齐方式。\verb|booktabs|~宏包的~\verb|\cmidrule|~命令用于横跨几列的横线。
+\begin{code}
+\begin{table}[htbp]
+\caption{跨栏表格}
+\centering
+\begin{tabular}{lll}
+ \toprule
+ & \multicolumn{2}{c}{常用工具} \\
+ \cmidrule{2-3}
+ 操作系统 & 发行版 & 编辑器 \\
+ \midrule
+ Windows & MikTeX & TeXnicCenter \\
+ Unix/Linux & TeX Live & Emacs \\
+ Mac OS & MacTeX & TeXShop \\
+ \bottomrule
+\end{tabular}
+\end{table}
+\end{code}
+
+\begin{table}[htbp]
+\caption{跨栏表格}
+\centering
+\begin{tabular}{lll}
+ \toprule
+ & \multicolumn{2}{c}{常用工具} \\
+ \cmidrule{2-3}
+ 操作系统 & 发行版 & 编辑器 \\
+ \midrule
+ Windows & MikTeX & TeXnicCenter \\
+ Unix/Linux & TeX Live & Emacs \\
+ Mac OS & MacTeX & TeXShop \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+跨行表格需要使用~\verb|multirow|~宏包,\verb|\multirow|~命令的前两个参数是竖跨的行数和宽度。
+\begin{code}
+\usepackage{multirow}
+...
+\begin{table}[htbp]
+\caption{跨行表格}
+\centering
+\begin{tabular}{lllc}
+\end{code}
+\begin{code}
+ \toprule
+ 操作系统 & 发行版 & 编辑器 & 用户体验\\
+ \midrule
+ Windows & MikTeX & TeXnicCenter &
+ \multirow{3}{*}{\centering 爽} \\
+ Unix/Linux & TeX Live & Emacs \\
+ Mac OS & MacTeX & TeXShop \\
+ \bottomrule
+\end{tabular}
+\end{table}
+\end{code}
+
+\begin{table}[htbp]
+\caption{跨行表格}
+\centering
+\begin{tabular}{lllc}
+ \toprule
+ 操作系统 & 发行版 & 编辑器 & 用户体验 \\
+ \midrule
+ Windows & MikTeX & TeXnicCenter &
+ \multirow{3}{*}{\centering 爽} \\
+ Unix/Linux & TeX Live & Emacs \\
+ Mac OS & MacTeX & TeXShop \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\section{彩色表格}
+彩色表格需要使用~\verb|colortbl|~宏包\citep{Carlisle_2001}提供的一些命令:\verb|\columncolor|、~\verb|\rowcolor|、\verb|\cellcolor|~等。
+\begin{code}
+\usepackage{colortbl}
+...
+\begin{table}[htbp]
+\caption{彩色表格}
+\centering
+\begin{tabular}{lll}
+ \toprule
+ 操作系统 & 发行版 & 编辑器 \\
+ \midrule
+ Windows & MikTeX & TeXnicCenter \\
+\end{code}
+\begin{code}
+ \rowcolor[gray]{.8} Unix/Linux & TeX Live & Emacs \\
+ Mac OS & MacTeX & TeXShop \\
+ \bottomrule
+\end{tabular}
+\end{table}
+\end{code}
+
+\begin{table}[htbp]
+\caption{彩色表格}
+\centering
+\begin{tabular}{lll}
+ \toprule
+ 操作系统 & 发行版 & 编辑器 \\
+ \midrule
+ Windows & MikTeX & TeXnicCenter \\
+ \rowcolor[gray]{.8} Unix/Linux & TeX Live & Emacs \\
+ Mac OS & MacTeX & TeXShop \\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+\section{长表格}
+有时表格太长要跨页,可以使用~\verb|longtable|~宏包\citep{Carlisle_2004}。\verb|\endfirsthead|、~\verb|\endhead|~命令用来定义首页表头和通用表头,\verb|\endfoot|、\verb|\endlastfoot|~命令用来定义通用表尾和末页表尾。
+\begin{code}
+\usepackage{longtable}
+...
+\begin{longtable}{ll}
+\caption{长表格} \\
+ \toprule
+ 作者 & 作品 \\
+ \midrule
+ \endfirsthead
+ \midrule
+ 作者 & 作品 \\
+ \midrule
+ \endhead
+ \midrule
+ \multicolumn{2}{r}{接下页\dots} \\
+\end{code}
+\begin{code}
+ \endfoot
+ \bottomrule
+ \endlastfoot
+ 白居易 & 汉皇重色思倾国,\\
+ & 御宇多年求不得。\\
+ & 杨家有女初长成,\\
+ & 养在深闺人未识。\\
+ & 天生丽质难自弃,\\
+ & 一朝选在君王侧。\\
+ & 回眸一笑百媚生,\\
+ & 六宫粉黛无颜色。\\
+ & 春寒赐浴华清池,\\
+ & 温泉水滑洗凝脂。\\
+ & 侍儿扶起娇无力,\\
+ & 始是新承恩泽时。\\
+ & 云鬓花颜金步摇,\\
+ & 芙蓉帐暖度春宵。\\
+ & 春宵苦短日高起,\\
+ & 从此君王不早朝。\\
