 ## hithesis是什么？
 
 hithesis
 旨在建立一个简单易用的哈尔滨工业大学学位论文LaTeX模板，包括本科论文、硕士论文、博士论文
 。现 在支持本科、硕士、博士论文，对其它格式的支持会陆续加入。
 hithesis 已收录在[CTAN](https://ctan.org/pkg/hithesis
-"CTAN")中，用户安装TeXLive将自带我工模板（版本日期>2017.08.28）。

  - 更傻更简单的选项，例如论文主文件，只需要在文档类的括号中填写本硕博选项，字体选项（设置弹性间距或者刚性间距），文科生选项（目录可以设成四级目录），非全日制类型等，轻松设定目标格式。
  - 自适应格式，例如图题和标题，标题字号在字数超过两行时自动由五号变小五号，实现自适应（硕博规范规定，字数多时用五号）
  - 自动化中英文索引（博士规范要求，有需要时候添加）
- - 图书馆提交论文级的书签设置

+博士论文在双面打印成册时，规范中没有明确规定是否要右翻页（右翻页是每一章的起始位
+置位于书的右侧页面），所以会出现DIY（或身不由己DIY）哪一处右翻页。
+`openright`选项设置为真时，会将所有章（即所有部分，包括前文和后文）起始设置成右翻页。
+如果想DIY（或身不由己DIY）在什么地方右翻页，将这个选项设置为false，然后在目标位
+置添加`\cleardoublepage`命令即可。

+最后向图书管提交的电子版不是右翻页且要求没有任何空白页，这时只需要设置选项`library=true`
+即可，这时候会强制`openright=false`。然后什么都不用做，就会出现如同`Sirius`同学

+%
+% \label{OnlyMainNiceMatrix}
+% 
+% The extension \pkg{nicematrix} provides the command |\OnlyMainNiceMatrix|
+% which is meant to be used in definitions of new column types. Its argument is
+% evaluated if and only if we are in the main part of the array, that is to say
+% not in an eventual exterior row. 
 %
+% For example, one may wish to define a new column type |?| in order to draw a
+% thick rule of width 1~pt. The following definition will do the job:
+%
+% \begin{Verbatim}
+% \newcolumntype{?}{!{\OnlyMainNiceMatrix{\vrule width 1 pt}}}

-%====================== BEGIN INSTRUCTIONS ===========================
-These plain text instructions may disappear soon.  The primary instructions
-are in ulem.ltx (ulem.pdf, ulem.dvi).
-
-ULEM is a package for LaTeX or plain TeX which provides various types of
-underlining that can stretch between words and be broken across lines.
-In LaTeX this style replaces italics with underlining in emphasized text
-given by \em or \emph -- but only if the text is delimited by braces.  A
-declaration \normalem (or the \usepackage option [normalem]) restores the
-normal \em behavior.  For underlining in plain TeX, \input ulem.sty, and
-use the \uline command.
-
-Unlike regular underlining, ulem allows line breaks, and even primitive
-hyphenation, within the underlined text; but it is far from perfect. It is
-most suitable for simple text like  {\em \LaTeX: A document preparation
-system\/}  that may need to be underlined in a manuscript submitted for
-publication.  Again, ulem will only replace \em and \emph when the text is
-delimited by explicit braces.
-
-The thickness of the underline rule is given by \ULthickness; use
-\renewcommand or \def (not \setlength) to change it.  The depth of the
-underline is controlled by the length \ULdepth.  The default value is a
-special flag which lets the current font control the depth.  You can set
-a particular value to \ULdepth (using \setlength) to force a particular
-depth, either locally for a special purpose, or for the document as a
-whole.  See the definition of \sout.
-
-Every word is typeset in an underlined box, so automatic hyphenation is
-normally disabled, but explicit discretionary hyphens (\-) will still be
-obeyed.  Several text-formatting commands are specially supported within
-the underlining:  \-, \ , ~, \\, \newline, \linebreak, \nolinebreak,
-\penalty, \hskip, \hspace, \hfil, \hfill, \hss.  Displayed math and \par
-are deliberately not supported to aid in the detection of runaway arguments
-(missing braces).  The special commands do have a problem: they end a
-group so any local assignments are lost.  
-
-The underlines continue between words, and stretch just like ordinary
-spaces do.  Since spaces delimit words, there may be some difficulty
-with syntactical spaces (e.g. "2.3 pt"). Some effort is made to handle
-such cases, but sometimes (such as \let\x= y) the space is interpreted
-incorrectly. You can usually solve the problem by enclosing the offending
-command in braces or in a macro (\newcommand\xeqy{\let\x= y}), but...
-
-One important incompatibility with braces and macro replacement:
-ALL THE TEXT IN BRACES OR COMING FROM A MACRO IS TYPESET IN A BOX.
-That is, braces will suppress stretching and linebreaks in the text they
-enclose.  Moreover, the specially-taken-care-of commands \-, \\, \newline
-and \linebreak are usually ignored if they appear inside extra braces.
-They operate only when the braces delimit a command parameter without
-introducing a level of grouping.  (Even though braces delimiting command
-parameters do not normally imply grouping, many commands will add their
-own grouping.)  Thus, you should try to limit inner braces to short bits of
-text or for delimiting parameters to commands. For emergency repairs, see
-the "Marat/Sade" example below.  Syntactical spaces inside braces never
-cause a problem, nor do spaces in math mode.
-
-Text produced by expansion of a command (macro) is boxed too, but \\, \
-and \- still work properly in the expansion text:
-        \newcommand\iff{if and only if} {\em \iff}
-does not allow any stretching or linebreaking between words, but
-        \newcommand\iff{if\ and\ only\ if} {\em \iff}
-allows stretching and linebreaking.  There is a problem though:  the
-\  between words closes a group and any local assignments will be lost,
-in particular, font changes and color changes.
-
-This loss of local assignments will break some other standard commands,
-(e.g., \cite) which produce multiple `words' using local assignments.
-The way to protect such commands is to bury them in an \mbox:
-        {\em every\-one agrees~\mbox{\cite{you,me}}.}
-
-Nested \em commands produce multiple underlining, but heed the warnings
-about braces above.  To get italics without underlining, use \it.  Nesting
-of other types of underline is also possible, but the `underlines' may
-overlap.
-
-HERE IS A SIMPLE EXAMPLE.
-
-\noindent 'Twas {\em brillig\/} and the {\em slithy~toves\/}
-did {\em gyre\/} and {\em gim\-ble\/} in the {\em wabe,\\[2pt] }
-All {\em mim\-sey\/} were the {\em boro\-goves\/} and
-the {\em mome raths outgrabe}.
-
-HERE IS A DIFFICULT EXAMPLE.
-
-\usepackage{ulem}
-\setlength\textwidth{3.3in}
-\begin{document}
-% \large
-No, I did {\em not} act in the movie {\em \emph{The} %    <<<<<<< Nested
-\emph{Persecu}\-\emph{tion} \emph{and} \emph{Assassination} \emph{of}
-\emph{Jean-Paul} \emph{Marat}, as per\-formed by the Inmates
-of the Asylum of Charenton under the Direc\-tion of the
-Marquis de~Sade!} But I {\em did} see it.
-\end{document}
-
-In the nested emphasis, \emph had to be given for each word separately
-so the spaces between could stretch and break into lines.  Even the
-discretionary hyphen (\-) in `Persecution' had to be outside the braces,
-but the hyphen in `Direction' was just fine because it was not in nested
-braces. The same applies to other special commands like \  and ~. Also,
-the spaces are printed with only a single underline because they are
-outside the nested \emph commands.  This example really illustrates that
-ulem does not handle nested emphasis very well!  Nevertheless, it is fine
-for simple things.
-
-Underlining can also be done according to \uline{this text}. To use this
-type of underlining, but have \em still produce italics, put the command
-\normalem in the preamble of the document or load ulem with
-\usepackage[normalem]{ulem}.
-
-Some variations on underlining are provided, including a wavey underline
-(\uwave{under-wave}), double underlines (\uuline{two lines under this}),
-dashed (\dashuline{dashes underneath}) or dotted (\dotuline{dots below})
-underlines,
-a line through text rather than under it (\sout{strike out}), and text
-crossed-out with /////// (\xout{cross out, X out}).  You can define your
-own styles following the examples provided.  The definition should be
-something like:
-
-\newcommand\command{\bgroup \markoverwith{something}\ULon}
-
-The "something" can be as simple as a single character, or as complex as
-you can keep track of.
-
-The various underlining commands are essentially textual, and will not
-work quite the same in math mode.  But since some font commands, like \bf,
-serve both for text and math, math mode is handled (in an approximate way).
-The performance in math mode is somewhat different from in text: there will
-be no line breaks or stretching in the underlined text, and the vertical
-positioning may not be right.  The results should be best for \uline,
-\uwave, \uuline, and any other truly UNDER-line you define.
-
-Any type of underlining can be substituted for any font-selection command
-by issuing a proper \useunder declaration:
-
-\useunder{\underlinecommand}{\fontdeclaration}{\fontcommand}
-
-e.g., \useunder{\uuline}{\bfseries}{\textbf} gives a double underline
-instead of bold face in LaTeX.  The commands \normalem and \ULforem switch
-underlining for \em off and on, respectively, and so do the \usepackage
-options [normalem] and [ULforem]. There is also the \usepackage style
-option [UWforbf] to replace boldface with a wavey underline.
-
-UWforbf does handle \bf in math mode, but it doesn't work in section titles,
-unfortunately, because the titles are not delimited by explicit braces when
-printed by the \section command.  For the present version, the \bfseries
-command still produces bold face, but \bf makes an under-wave. To get under-
-waved section titles you can do
-
-\renewcommand\@seccntformat[1]{\uwave{\csname the#1\endcsname}\hskip 1em}
-
-and later specify \section[...]{\uwave{...}}.
-
-In plain TeX there is no \textbf so you should use \useunder{\UWave}{\bf}{}.
-You can even skip a step and define the underline or overprint with \useunder:
-\useunder{\bgroup\markoverwith{!}\ULon}{\sf}{}
-
-Some commands, such as \\ and \hskip are given special treatment, but 
-others (like \marginpar) are not.  Support for others can be added by 
-assigning special meanings in the token register \UL@hook.  (In LaTeX do 
-\addto@hook\UL@hook{\let\command\ULversion}.)  The UL versions of commands 
-should be modelled on \UL@hskip or \UL@cr, and should include the test 
-"\ifx\ \LA@space".  For example, support for "\marginpar" is added through
-the hook mechanism.
-
-All the underlining commands are robust in LaTeX.
