+% \section{模板介绍}
+% \njurepo\ (\textbf{N}an\textbf{jing} \textbf{U}niversity \LaTeX\ Versatile \textbf{Repo}rt Template)是为南京大学本科生设计的一个免于配置的作业、实验报告模板。希望它可以使你的作业/实验报告不会因形式上的缺陷导致评分的下降。
+%
+% 该文档格式基于 ctexbook, 主要完成了除了主体内容以外的几乎\textbf{全部}工作。同时，通过使用 Github 版本宏包，你还可以更好的管理自己的 $\LaTeX$ 文档。
+%
+% 本文档将尽量完整的介绍模板的使用方法，如有不清楚之处可以参考示例文档或者根据第 3.1 节说明提问，有兴趣者都可以参与完善此手册，也非常欢迎对代码的贡献。
+% 
+% \section{安装}
+% \label{sec:installation}
+% \subsection{CTAN}
+% 本宏包已被收纳于 CTAN 中，凡安装完整版 Texlive 用户可直接使用：
+% \begin{latex} 
+% \usepackage{njurepo} 
+% \end{latex}
+%
+% \subsection{Github}
+% 想获得最新版本的 \njurepo 请前往 Github 主页下载：https://github.com/zhengzangw/njurepo 
+% 
+% 同时，面向 Github 版本的说明主要在 README.md 中，如果使用的是 Github 版本，请阅读 README.md
+%
+% \subsection{模板的组成}
+% 下表列出了\njurepo 的主要文件及其功能介绍：
+%
+% \begin{longtable}{l|p{8cm}}
+% \toprule
+% {\heiti 文件（夹）} & {\heiti 功能描述}\\\midrule
+% \endfirsthead
+% \midrule
+% {\heiti 文件（夹）} & {\heiti 功能描述}\\\midrule
+% \endhead
+% \endfoot
+% \endlastfoot
+% njurepo.ins & \textsc{DocStrip} 驱动文件（开发用） \\
+% njurepo.dtx & \textsc{DocStrip} 源文件（开发用）\\\midrule
+% resources/ & 资源路径\\
+% resources/logos/ & 示例文档资源路径\\
+% parts/ & 具体内容\\
+% parts/examples/ & 示例文档具体内容\\
+% ref/ & 参考文献和参考文献样式文件\\
+% njurepo.cls & 模板类文件\\
+% Makefile & 自动运行脚本 \\
+% util.py & 实用管理工具 \\
+% README.md & 说明文件 \\
+% \textbf{njurepo.pdf} & 用户手册（本文档）\\ \bottomrule
+% \end{longtable}
+%
+% \subsection{生成模板}
+% 使用Makefile或\XeLaTeX 生成模板文件
+% \begin{shell}
+% make cls
+% \end{shell}
+%
+% \subsection{生成论文}
+% \subsubsection{latexmk}
+% latexmk 命令支持全自动生成\LaTeX{}编写的文档，并且支持使用不同的工具链来进行生成，它会自动运行多次工具直到交叉引用都被解决。下面给出了一个用 latexmk 调用 xelatex 生成最终文档的示例:
+% \begin{shell}
+% latexmk -xelatex main
+% \end{shell}
+%
+% \subsection{升级}
+% 在github上下载最新版，运行:
+% \begin{shell}
+% make cls
+% \end{shell}
+%
+% 生成新的类文件和配置文件即可。也可以直接拷贝 njurepo.cls，免去上面命令的执行。
+% 
+%
+% \section{使用说明}
+% \subsection{示例文件}
+% 推荐从模板自带的示例文档入手，其中包括了论文写作用到的所有命令及其使用方法，只需要用自己的内容进行相应替换就可以。对于不清楚的命令可以查阅本手册。下面的例子描述了模板中章节的组织形式，来自于示例文档，具体内容可以参考模板附带的 main.tex 和 parts/examples/。
+% \begin{latex}
+% \documentclass[language=english,open=any]{njurepo}
+% \begin{document}
+% \frontmatter
+% \input{parts/examples/cover}
+% \input{parts/examples/abstract}

+% \end{latex}
+%
+% \subsection{选项}
+% \label{sec:option}
+% \DescribeOption{language}
+% 论文的主要语言（默认：中文）。可选：\option{chinese}，\option{english}。决定了封面、标题、定理的语言。
+% \DescribeOption{open}
+% 正规出版物的章节出现在奇数页，也就是右手边的页面，这就是 \option{right}，。在这种情况下，如果前一章的最后一页也是奇数，那么模板会自动生成一个纯粹的空白页。
+% 提交的作业如果是电子稿的话，可以使用连续页，即使用\option{any}
+% \DescribeOption{wide}
+% 是否使用宽页面。如果生成作业的话，宽页面或许好看。
+% \DescribeOption{draft}
+% 是否生成水印。生成的水印为 Draft 表示此文档尚为草稿
+%
+% \subsection{字体配置}
+% \label{sec:font-config}
+% 使用\CTeX\ 默认字体配置
+% \subsubsection{字体命令}
+% \label{sec:fontcmds}
+% \myentry{字体}
+% \DescribeMacro{\songti}
+% \DescribeMacro{\fangsong}
+% \DescribeMacro{\heiti}
+% \DescribeMacro{\kaishu}
+% 用来切换宋体、仿宋、黑体、楷体四种基本字体。
+% \myentry{字号}
+% \DescribeMacro{\chuhao}
+% \DescribeMacro{\xiaochu}
+% \DescribeMacro{\yihao}
+% \DescribeMacro{\xiaoyi}
+% \DescribeMacro{\bahao}
+% 定义字体大小，分别为
+% \begin{center}
+% \begin{tabular}{llllll}
+% \toprule
+% \cs{chuhao} & \cs{xiaochu} & \cs{yihao}  & \cs{xiaoyi}    & \cs{erhao}  & \cs{xiaoer}\\
+% \cs{sanhao} & \cs{xiaosan} & \cs{sihao}  & \cs{banxiaosi} & \cs{xiaosi} & \cs{dawu}\\
+% \cs{wuhao}  & \cs{xiaowu}  & \cs{liuhao} & \cs{xiaoliu}   & \cs{qihao}  & \cs{bahao}\\\bottomrule
+% \end{tabular}
+% \end{center}
+% 使用方法为：\cs{command}\oarg{num}，其中 command 为字号命令，num 为行距。比
+% 如 \cs{xiaosi}[1.5] 表示选择小四字体，行距 1.5 倍。写作指南要求表格中的字体
+% 是 \cs{dawu}，模板已经设置好了。
+%
+% \subsection{封面信息}
+% 仿照parts/examples/cover.tex 进行设置
+% \subsection{表格}
+% \DescribeMacro{\figoptadd}
+% \DescribeMacro{\figoptaddcap}

+%
+% \pkg{fancyhdr} 定义页眉页脚很方便，但是有一个非常隐蔽的坑。通过 \pkg{fancyhdr}
+% 定义的样式在第一次被调用时会修改 \cs{chaptermark}，这会导致页眉信息错误（多余
+% 章号并且英文大写）。这是因为在原始的 \file{book.cls} 中定义如下（大意）：
+% \begin{latex}
+% \newcommand\chaptername{Chapter}
+% \newcommand\@chapapp{\chaptername}
+% \def\chaptermark#1{
+%   \markboth{\MakeUppercase{\@chapapp\ \thechapter}}{}}
+% \end{latex}
+% 很显然这个 \cs{\@chapapp} 不适合中文，因此我们使用\cs{CTEXthechapter}（
+% 如，“第 x 章”），同时会将 \cs{MakeUppercase} 去掉。也就是说我们会做如下动作：
+% \begin{latex}
+% \renewcommand{\chaptermark}[1]{\@mkboth{\CTEXthechapter\hskip\ccwd#1}{}}
+% \end{latex}
+% 但，\pkg{fancyhdr} 不知何故在 \cs{ps@fancy} 中对 \cs{chaptermark} 进行重定义
+% （其实一模一样），而这个 \cs{ps@fancy} 会在 \cs{fancypagestyle} 中使用，如下：
+% \begin{latex}
+% \newcommand{\fancypagestyle}[2]{%
+%   \@namedef{ps@#1}{\let\fancy@gbl\relax#2\relax\ps@fancy}}
+% \end{latex}
+% 这样的话，\cs{ps@fancy} 会在 \pkg{fancyhdr} 定义的任何样式首次样被激活时调用，从
+% 而覆盖我们的 \cs{chaptermark} 定义（后续样式再激活不会重复覆盖）。所以我们采用如下
+% 方法解决：
+%    \begin{macrocode}
+\AtBeginDocument{%
+  \pagestyle{nju@empty}
+  \renewcommand{\chaptermark}[1]{\@mkboth{\CTEXthechapter\hskip\ccwd#1}{}}}
+%    \end{macrocode}
+%
+% 各级标题格式设置。

+%   前空 24 磅，段后空 18 磅。本科要求：段前段后间距 30/20 pt，行距 20pt。但正文
+%   章节 30pt 的话和样例效果不一致。
+% \item[section] 一级节标题，例如：\fbox{2.1 实验装置与实验方法}。节标题序号与标
+%   题名之间空一个汉字符（下同）。采用黑体四号（14pt）字居左书写，行距为固定

+% \begin{macro}{\nju@chapter*}
+% 默认的 \cs{chapter*} 很难同时满足研究生院和本科生的论文要求。本科论文要求所有的
+% 章都出现在目录里，比如摘要、Abstract、主要符号表等，所以可以简单的扩展默
+% 认\cs{chapter*} 实现这个目的。但是研究生又不要这些出现在目录中，而且致谢和声明
+% 部分的章名、页眉和目录都不同，所以定义一个灵活的 \cs{nju@chapter*} 专门处理这些
+% 要求。
+%
+% \cs{nju@chapter*}\oarg{tocline}\marg{title}\oarg{header}: tocline 是出现在目录
+% 中的条目，如果为空则此 chapter 不出现在目录中，如果省略表示目录出现 title；
+% title 是章标题；header 是页眉出现的标题，如果忽略则取 title。通过这个宏我才真
+% 正体会到 \TeX\ macro 的力量！

+%
+% \begin{macro}{\equcaption}
+%   本命令只是为了生成公式列表，所以这个 caption 是假的。如果要编号最好用
+%    equation 环境，如果是其它编号环境，请手动添加 \cs{equcaption}。
+% 用法如下：
+%
+% \cs{equcaption}\marg{counter}
+%
+% \marg{counter} 指定出现在索引中的编号，一般取 \cs{theequation}，如果你是用
+%  \pkg{amsmath} 的 \cs{tag}，那么默认是 \cs{tag} 的参数；除此之外可能需要你
+% 手工指定。
+%
+%    \begin{macrocode}

+%    \end{macrocode}
+%
+% 下面修改 \pkg{natbib} 的引用格式，主要是将页码写在上标位置。

+%

+\unskip\kern\p@\textsuperscript{\NAT@@open#1\NAT@@close\if*#3*\else#3\fi}%

+%

+%    \begin{macrocode}
+\patchcmd{\NAT@citex}{%

+  \if\relax\NAT@date\relax\else\NAT@@close\fi

+%    \end{macrocode}
+%
+% 在顺序编码制下，\pkg{natbib} 只有在三个以上连续文献引用才会使用连接号，
+% 这里修改为允许两个引用使用连接号。
+%    \begin{macrocode}
+\patchcmd{\NAT@citexnum}{%
