-The LaTeX Project Public License
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
-
-LPPL Version 1.3c  2008-05-04
-
-Copyright 1999 2002-2008 LaTeX3 Project
-    Everyone is allowed to distribute verbatim copies of this
-    license document, but modification of it is not allowed.
-
-
-PREAMBLE
-========
-
-The LaTeX Project Public License (LPPL) is the primary license under
-which the LaTeX kernel and the base LaTeX packages are distributed.
-
-You may use this license for any work of which you hold the copyright
-and which you wish to distribute.  This license may be particularly
-suitable if your work is TeX-related (such as a LaTeX package), but 
-it is written in such a way that you can use it even if your work is 
-unrelated to TeX.
-
-The section `WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE',
-below, gives instructions, examples, and recommendations for authors
-who are considering distributing their works under this license.
-
-This license gives conditions under which a work may be distributed
-and modified, as well as conditions under which modified versions of
-that work may be distributed.
-
-We, the LaTeX3 Project, believe that the conditions below give you
-the freedom to make and distribute modified versions of your work
-that conform with whatever technical specifications you wish while
-maintaining the availability, integrity, and reliability of
-that work.  If you do not see how to achieve your goal while
-meeting these conditions, then read the document `cfgguide.tex'
-and `modguide.tex' in the base LaTeX distribution for suggestions.
-
-
-DEFINITIONS
-===========
-
-In this license document the following terms are used:
-
-   `Work'
-    Any work being distributed under this License.
-    
-   `Derived Work'
-    Any work that under any applicable law is derived from the Work.
-
-   `Modification' 
-    Any procedure that produces a Derived Work under any applicable
-    law -- for example, the production of a file containing an
-    original file associated with the Work or a significant portion of
-    such a file, either verbatim or with modifications and/or
-    translated into another language.
-
-   `Modify'
-    To apply any procedure that produces a Derived Work under any
-    applicable law.
-    
-   `Distribution'
-    Making copies of the Work available from one person to another, in
-    whole or in part.  Distribution includes (but is not limited to)
-    making any electronic components of the Work accessible by
-    file transfer protocols such as FTP or HTTP or by shared file
-    systems such as Sun's Network File System (NFS).
-
-   `Compiled Work'
-    A version of the Work that has been processed into a form where it
-    is directly usable on a computer system.  This processing may
-    include using installation facilities provided by the Work,
-    transformations of the Work, copying of components of the Work, or
-    other activities.  Note that modification of any installation
-    facilities provided by the Work constitutes modification of the Work.
-
-   `Current Maintainer'
-    A person or persons nominated as such within the Work.  If there is
-    no such explicit nomination then it is the `Copyright Holder' under
-    any applicable law.
-
-   `Base Interpreter' 
-    A program or process that is normally needed for running or
-    interpreting a part or the whole of the Work.    
-
-    A Base Interpreter may depend on external components but these
-    are not considered part of the Base Interpreter provided that each
-    external component clearly identifies itself whenever it is used
-    interactively.  Unless explicitly specified when applying the
-    license to the Work, the only applicable Base Interpreter is a
-    `LaTeX-Format' or in the case of files belonging to the 
-    `LaTeX-format' a program implementing the `TeX language'.
-
-
-
-CONDITIONS ON DISTRIBUTION AND MODIFICATION
-===========================================
-
-1.  Activities other than distribution and/or modification of the Work
-are not covered by this license; they are outside its scope.  In
-particular, the act of running the Work is not restricted and no
-requirements are made concerning any offers of support for the Work.
-
-2.  You may distribute a complete, unmodified copy of the Work as you
-received it.  Distribution of only part of the Work is considered
-modification of the Work, and no right to distribute such a Derived
-Work may be assumed under the terms of this clause.
-
-3.  You may distribute a Compiled Work that has been generated from a
-complete, unmodified copy of the Work as distributed under Clause 2
-above, as long as that Compiled Work is distributed in such a way that
-the recipients may install the Compiled Work on their system exactly
-as it would have been installed if they generated a Compiled Work
-directly from the Work.
-
-4.  If you are the Current Maintainer of the Work, you may, without
-restriction, modify the Work, thus creating a Derived Work.  You may
-also distribute the Derived Work without restriction, including
-Compiled Works generated from the Derived Work.  Derived Works
-distributed in this manner by the Current Maintainer are considered to
-be updated versions of the Work.
-
-5.  If you are not the Current Maintainer of the Work, you may modify
-your copy of the Work, thus creating a Derived Work based on the Work,
-and compile this Derived Work, thus creating a Compiled Work based on
-the Derived Work.
-
-6.  If you are not the Current Maintainer of the Work, you may
-distribute a Derived Work provided the following conditions are met
-for every component of the Work unless that component clearly states
-in the copyright notice that it is exempt from that condition.  Only
-the Current Maintainer is allowed to add such statements of exemption 
-to a component of the Work. 
-
-  a. If a component of this Derived Work can be a direct replacement
-     for a component of the Work when that component is used with the
-     Base Interpreter, then, wherever this component of the Work
-     identifies itself to the user when used interactively with that
-     Base Interpreter, the replacement component of this Derived Work
-     clearly and unambiguously identifies itself as a modified version
-     of this component to the user when used interactively with that
-     Base Interpreter.
-     
-  b. Every component of the Derived Work contains prominent notices
-     detailing the nature of the changes to that component, or a
-     prominent reference to another file that is distributed as part
-     of the Derived Work and that contains a complete and accurate log
-     of the changes.
-  
-  c. No information in the Derived Work implies that any persons,
-     including (but not limited to) the authors of the original version
-     of the Work, provide any support, including (but not limited to)
-     the reporting and handling of errors, to recipients of the
-     Derived Work unless those persons have stated explicitly that
-     they do provide such support for the Derived Work.
-
-  d. You distribute at least one of the following with the Derived Work:
-
-       1. A complete, unmodified copy of the Work; 
-          if your distribution of a modified component is made by
-          offering access to copy the modified component from a
-          designated place, then offering equivalent access to copy
-          the Work from the same or some similar place meets this
-          condition, even though third parties are not compelled to
-          copy the Work along with the modified component;
-
-       2. Information that is sufficient to obtain a complete,
-          unmodified copy of the Work.
-
-7.  If you are not the Current Maintainer of the Work, you may
-distribute a Compiled Work generated from a Derived Work, as long as
-the Derived Work is distributed to all recipients of the Compiled
-Work, and as long as the conditions of Clause 6, above, are met with
-regard to the Derived Work.
-
-8.  The conditions above are not intended to prohibit, and hence do not
-apply to, the modification, by any method, of any component so that it
-becomes identical to an updated version of that component of the Work as
-it is distributed by the Current Maintainer under Clause 4, above.
-
-9.  Distribution of the Work or any Derived Work in an alternative
-format, where the Work or that Derived Work (in whole or in part) is
-then produced by applying some process to that format, does not relax or
-nullify any sections of this license as they pertain to the results of
-applying that process.
-     
-10. a. A Derived Work may be distributed under a different license
-       provided that license itself honors the conditions listed in
-       Clause 6 above, in regard to the Work, though it does not have
-       to honor the rest of the conditions in this license.
-      
-    b. If a Derived Work is distributed under a different license, that
-       Derived Work must provide sufficient documentation as part of
-       itself to allow each recipient of that Derived Work to honor the 
-       restrictions in Clause 6 above, concerning changes from the Work.
-
-11. This license places no restrictions on works that are unrelated to
-the Work, nor does this license place any restrictions on aggregating
-such works with the Work by any means.
-
-12.  Nothing in this license is intended to, or may be used to, prevent
-complete compliance by all parties with all applicable laws.
-
-
-NO WARRANTY
-===========
-
-There is no warranty for the Work.  Except when otherwise stated in
-writing, the Copyright Holder provides the Work `as is', without
-warranty of any kind, either expressed or implied, including, but not
-limited to, the implied warranties of merchantability and fitness for a
-particular purpose.  The entire risk as to the quality and performance
-of the Work is with you.  Should the Work prove defective, you assume
-the cost of all necessary servicing, repair, or correction.
-
-In no event unless required by applicable law or agreed to in writing
-will The Copyright Holder, or any author named in the components of the
-Work, or any other party who may distribute and/or modify the Work as
-permitted above, be liable to you for damages, including any general,
-special, incidental or consequential damages arising out of any use of
-the Work or out of inability to use the Work (including, but not limited
-to, loss of data, data being rendered inaccurate, or losses sustained by
-anyone as a result of any failure of the Work to operate with any other
-programs), even if the Copyright Holder or said author or said other
-party has been advised of the possibility of such damages.
-
-
-MAINTENANCE OF THE WORK
-=======================
-
-The Work has the status `author-maintained' if the Copyright Holder
-explicitly and prominently states near the primary copyright notice in
-the Work that the Work can only be maintained by the Copyright Holder
-or simply that it is `author-maintained'.
-
-The Work has the status `maintained' if there is a Current Maintainer
-who has indicated in the Work that they are willing to receive error
-reports for the Work (for example, by supplying a valid e-mail
-address). It is not required for the Current Maintainer to acknowledge
-or act upon these error reports.
-
-The Work changes from status `maintained' to `unmaintained' if there
-is no Current Maintainer, or the person stated to be Current
-Maintainer of the work cannot be reached through the indicated means
-of communication for a period of six months, and there are no other
-significant signs of active maintenance.
-
-You can become the Current Maintainer of the Work by agreement with
-any existing Current Maintainer to take over this role.
-
-If the Work is unmaintained, you can become the Current Maintainer of
-the Work through the following steps:
-
- 1.  Make a reasonable attempt to trace the Current Maintainer (and
-     the Copyright Holder, if the two differ) through the means of
-     an Internet or similar search.
-
- 2.  If this search is successful, then enquire whether the Work
-     is still maintained.
-
-  a. If it is being maintained, then ask the Current Maintainer
-     to update their communication data within one month.
-     
-  b. If the search is unsuccessful or no action to resume active
-     maintenance is taken by the Current Maintainer, then announce
-     within the pertinent community your intention to take over
-     maintenance.  (If the Work is a LaTeX work, this could be
-     done, for example, by posting to comp.text.tex.)
-
- 3a. If the Current Maintainer is reachable and agrees to pass
-     maintenance of the Work to you, then this takes effect
-     immediately upon announcement.
-     
-  b. If the Current Maintainer is not reachable and the Copyright
-     Holder agrees that maintenance of the Work be passed to you,
-     then this takes effect immediately upon announcement.  
-    
- 4.  If you make an `intention announcement' as described in 2b. above
-     and after three months your intention is challenged neither by
-     the Current Maintainer nor by the Copyright Holder nor by other
-     people, then you may arrange for the Work to be changed so as
-     to name you as the (new) Current Maintainer.
-     
- 5.  If the previously unreachable Current Maintainer becomes
-     reachable once more within three months of a change completed
-     under the terms of 3b) or 4), then that Current Maintainer must
-     become or remain the Current Maintainer upon request provided
-     they then update their communication data within one month.
-
-A change in the Current Maintainer does not, of itself, alter the fact
-that the Work is distributed under the LPPL license.
-
-If you become the Current Maintainer of the Work, you should
-immediately provide, within the Work, a prominent and unambiguous
-statement of your status as Current Maintainer.  You should also
-announce your new status to the same pertinent community as
-in 2b) above.
-
-
-WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE
-======================================================
-
-This section contains important instructions, examples, and
-recommendations for authors who are considering distributing their
-works under this license.  These authors are addressed as `you' in
-this section.
-
-Choosing This License or Another License
-----------------------------------------
-
-If for any part of your work you want or need to use *distribution*
-conditions that differ significantly from those in this license, then
-do not refer to this license anywhere in your work but, instead,
-distribute your work under a different license.  You may use the text
-of this license as a model for your own license, but your license
-should not refer to the LPPL or otherwise give the impression that
-your work is distributed under the LPPL.
-
-The document `modguide.tex' in the base LaTeX distribution explains
-the motivation behind the conditions of this license.  It explains,
-for example, why distributing LaTeX under the GNU General Public
-License (GPL) was considered inappropriate.  Even if your work is
-unrelated to LaTeX, the discussion in `modguide.tex' may still be
-relevant, and authors intending to distribute their works under any
-license are encouraged to read it.
-
-A Recommendation on Modification Without Distribution
------------------------------------------------------
-
-It is wise never to modify a component of the Work, even for your own
-personal use, without also meeting the above conditions for
-distributing the modified component.  While you might intend that such
-modifications will never be distributed, often this will happen by
-accident -- you may forget that you have modified that component; or
-it may not occur to you when allowing others to access the modified
-version that you are thus distributing it and violating the conditions
-of this license in ways that could have legal implications and, worse,
-cause problems for the community.  It is therefore usually in your
-best interest to keep your copy of the Work identical with the public
-one.  Many works provide ways to control the behavior of that work
-without altering any of its licensed components.
-
-How to Use This License
------------------------
-
-To use this license, place in each of the components of your work both
-an explicit copyright notice including your name and the year the work
-was authored and/or last substantially modified.  Include also a
-statement that the distribution and/or modification of that
-component is constrained by the conditions in this license.
-
-Here is an example of such a notice and statement:
-
-  %% pig.dtx
-  %% Copyright 2005 M. Y. Name
-  %
-  % This work may be distributed and/or modified under the
-  % conditions of the LaTeX Project Public License, either version 1.3
-  % of this license or (at your option) any later version.
-  % The latest version of this license is in
-  %   http://www.latex-project.org/lppl.txt
-  % and version 1.3 or later is part of all distributions of LaTeX
-  % version 2005/12/01 or later.
-  %
-  % This work has the LPPL maintenance status `maintained'.
-  % 
-  % The Current Maintainer of this work is M. Y. Name.
-  %
-  % This work consists of the files pig.dtx and pig.ins
-  % and the derived file pig.sty.
-
-Given such a notice and statement in a file, the conditions
-given in this license document would apply, with the `Work' referring
-to the three files `pig.dtx', `pig.ins', and `pig.sty' (the last being
-generated from `pig.dtx' using `pig.ins'), the `Base Interpreter'
-referring to any `LaTeX-Format', and both `Copyright Holder' and
-`Current Maintainer' referring to the person `M. Y. Name'.
-
-If you do not want the Maintenance section of LPPL to apply to your
-Work, change `maintained' above into `author-maintained'.  
-However, we recommend that you use `maintained', as the Maintenance
-section was added in order to ensure that your Work remains useful to
-the community even when you can no longer maintain and support it
-yourself.
-
-Derived Works That Are Not Replacements
----------------------------------------
-
-Several clauses of the LPPL specify means to provide reliability and
-stability for the user community. They therefore concern themselves
-with the case that a Derived Work is intended to be used as a
-(compatible or incompatible) replacement of the original Work. If
-this is not the case (e.g., if a few lines of code are reused for a
-completely different task), then clauses 6b and 6d shall not apply.
-
-
-Important Recommendations
--------------------------
-
- Defining What Constitutes the Work
-
-   The LPPL requires that distributions of the Work contain all the
-   files of the Work.  It is therefore important that you provide a
-   way for the licensee to determine which files constitute the Work.
-   This could, for example, be achieved by explicitly listing all the
-   files of the Work near the copyright notice of each file or by
-   using a line such as:
-
-    % This work consists of all files listed in manifest.txt.
-   
-   in that place.  In the absence of an unequivocal list it might be
-   impossible for the licensee to determine what is considered by you
-   to comprise the Work and, in such a case, the licensee would be
-   entitled to make reasonable conjectures as to which files comprise
-   the Work.

-\begin{lstlisting}[frame=none]  
-  \documentclass[geye]{elegantnote} % or
-  \documentclass[mode=geye]{elegantnote}
-  \documentclass[hazy]{elegantnote} % or
-  \documentclass[mode=hazy]{elegantnote}
-\end{lstlisting}
-
-\begin{remark}
-  如果你想为自己的文档添加底色，可以在导言区添加下面设置：
-  \begin{lstlisting}

-\end{lstlisting}
-\begin{note}
-也可以采取直接赋值的方法选择屏幕，比如：
-\end{note}
-\begin{lstlisting}[frame=none]  
-  \documentclass[pad]{elegantnote}
-  \documentclass[kindle]{elegantnote}
-  \documentclass[pc]{elegantnote}
-  \documentclass[normal]{elegantnote}
-  \documentclass[screen]{elegantnote}
-\end{lstlisting}
-
-\begin{note}
-  如果想要正常的 A4 大小的 PDF，需要选择 \lstinline{device=normal}。
-\end{note}
-
-
-\subsection{数学字体选项}
-
-本模板定义了一个数学字体选项（\lstinline{math}），可选项有三个：
-\begin{enumerate}
-  \item \lstinline{math=cm}（默认），使用 \LaTeX{} 默认数学字体（推荐，无需声明）；
-  \item \lstinline{math=newtx}，使用 \lstinline{newtxmath} 设置数学字体（潜在问题比较多）。
-  \item \lstinline{math=mtpro2}，使用 \lstinline{mtpro2} 宏包设置数学字体，要求用户已经成功安装此宏包。
-\end{enumerate}
-
-
-\subsection{中文字体选项}
-模板提供中文字体选项 \lstinline{chinesefont}，可选项有
-\begin{enumerate}
-\item \lstinline{ctexfont}：默认选项，使用 \lstinline{ctex} 宏包根据系统自行选择字体，可能存在字体缺失的问题，更多内容参考 \lstinline{ctex} 宏包\href{https://ctan.org/pkg/ctex}{官方文档}\footnote{可以使用命令提示符，输入 \lstinline{texdoc ctex} 调出本地 \lstinline{ctex} 宏包文档}。
-\item \lstinline{founder}：方正字体选项（需要用户安装字体），调用 \lstinline{ctex} 宏包并且使用 \lstinline{fontset=none} 选项，然后设置字体为方正四款免费字体，方正字体下载注意事项见后文。
-\item \lstinline{nofont}：调用 \lstinline{ctex} 宏包并且使用 \lstinline{fontset=none} 选项，不设定中文字体，用户可以自行设置中文字体，具体见后文。
-\end{enumerate}
-
-\noindent \textbf{注意：} 使用 \lstinline{founder} 选项或者 \lstinline{nofont} 时，必须使用 \hologo{XeLaTeX} 进行编译。
-
-\subsubsection{方正字体选项}
-由于使用 \lstinline{ctex} 宏包默认调用系统已有的字体，部分系统字体缺失严重，因此，用户希望能够使用其它字体，我们推荐使用方正字体。方正的{\songti 方正书宋}、{\heiti 方正黑体}、{\kaishu 方正楷体}、{\fangsong 方正仿宋}四款字体均可免费试用，且可用于商业用途。用户可以自行从\href{http://www.foundertype.com/}{方正字体官网}下载此四款字体，在下载的时候请\textbf{务必}注意选择 GBK 字符集，也可以使用 \href{https://www.latexstudio.net/}{\LaTeX{} 工作室}提供的\href{https://pan.baidu.com/s/1BgbQM7LoinY7m8yeP25Y7Q}{方正字体，提取码为：njy9} 进行安装。安装时，{\kaishu Win 10 用户请右键选择为全部用户安装，否则会找不到字体。}

-
-\subsubsection{其他中文字体}
-如果你想完全自定义字体\footnote{这里仍然以方正字体为例。}，你可以选择 \lstinline{chinesefont=nofont}，然后在导言区设置，参考代码如下：
-\begin{lstlisting}
-  \setCJKmainfont[BoldFont={FZHei-B01},ItalicFont={FZKai-Z03}]{FZShuSong-Z01}
-  \setCJKsansfont[BoldFont={FZHei-B01}]{FZKai-Z03}
-  \setCJKmonofont[BoldFont={FZHei-B01}]{FZFangSong-Z02}
-  \setCJKfamilyfont{zhsong}{FZShuSong-Z01}
-  \setCJKfamilyfont{zhhei}{FZHei-B01}
-  \setCJKfamilyfont{zhkai}[BoldFont={FZHei-B01}]{FZKai-Z03}
-  \setCJKfamilyfont{zhfs}[BoldFont={FZHei-B01}]{FZFangSong-Z02}
-  \newcommand*{\songti}{\CJKfamily{zhsong}}
-  \newcommand*{\heiti}{\CJKfamily{zhhei}}
-  \newcommand*{\kaishu}{\CJKfamily{zhkai}}
-  \newcommand*{\fangsong}{\CJKfamily{zhfs}}
-\end{lstlisting}
-
-
-\subsection[颜色主题]{颜色主题\footnote{测试章节脚注。}}
-
-本模板内置 5 套颜色主题，分别是 \textcolor{eblue}{blue}（默认），\textcolor{egreen}{green}， \textcolor{ecyan}{cyan}， \textcolor{sakura}{sakura} 和 \textcolor{black}{black}。如果不需要颜色，可以选择黑色（black）主题。颜色主题的设置方法：
-\begin{lstlisting}[frame=none]  
-  \documentclass[green]{elegantnote}
-  \documentclass[color=green]{elegantnote}
-  ...
-  \documentclass[black]{elegantnote}
-  \documentclass[color=black]{elegantnote}
-\end{lstlisting}
-
-
-\subsection{语言模式}
-
-本模板内含两套语言环境，改变语言环境会改变图表标题的引导词（图，表），文章结构词（比如目录，参考文献等），以及定理环境中的引导词（比如定理，引理等）。不同语言模式的启用如下：
-\begin{lstlisting}[frame=none]  
-  \documentclass[cn]{elegantnote} 
-  \documentclass[lang=cn]{elegantnote} 
-  \documentclass[en]{elegantnote} 
-  \documentclass[lang=en]{elegantnote}
-\end{lstlisting}
-
-\begin{note}
-只有中文模式才可输入中文，如果需要在英文模式下输入中文，可以自行添加 \lstinline{ctex} 宏包\footnote{需要使用 \lstinline{scheme=plain} 选项才不会把标题改为中文。}或者使用 \lstinline{xeCJK} 宏包设置字体。另外如果在笔记中使用了抄录环境（\lstinline{lstlisting}），并且里面有中文字符，请务必使用 \hologo{XeLaTeX} 编译。
-\end{note}
-
-
-\subsection{定理类环境}
-
-此模板采用了 \lstinline{amsthm} 中的定理样式，使用了 4 类定理样式，所包含的环境分别为
-\begin{itemize}
-  \item \textbf{定理类}：theorem，lemma，proposition，corollary；
-  \item \textbf{定义类}：definition，conjecture，example；
-  \item \textbf{备注类}：remark，note，case；
-  \item \textbf{证明类}：proof。
-\end{itemize}
-
-\begin{remark}
-在选用 \lstinline{lang=cn} 时，定理类环境的引导词全部会改为中文。
-\end{remark}
-
-
-\section{写作示例}
-
-我们将通过三个步骤定义可测函数的积分。首先定义非负简单函数的积分。以下设 $E$ 是 $\mathcal{R}^n$ 中的可测集。
-
-\begin{definition}[可积性]
-设 $ f(x)=\sum\limits_{i=1}^{k} a_i \chi_{A_i}(x)$ 是 $E$ 上的非负简单函数，其中 $\{A_1,A_2,\ldots$, $A_k\}$ 是 $E$ 上的一个可测分割，$a_1,a_2,\ldots,a_k$ 是非负实数。定义 $f$ 在 $E$ 上的积分为 1. 3
-\begin{equation}
-   \label{inter}
-   \int_{E} f dx = \sum_{i=1}^k a_i m(A_i).
-\end{equation}
-一般情况下 $0 \leq \int_{E} f dx \leq \infty$。若 $\int_{E} f dx < \infty$，则称 $f$ 在 $E$ 上可积。
-\end{definition}
-
-一个自然的问题是，Lebesgue 积分与我们所熟悉的 Riemann 积分有什么联系和区别？之后我们将详细讨论 Riemann 积分与 Lebesgue 积分的关系。这里只看一个简单的例子。设 $D(x)$ 是区间 $[0,1]$ 上的 Dirichlet 函数。即 $D(x)=\chi_{Q_0}(x)$，其中 $Q_0$ 表示 $[0,1]$ 中的有理数的全体。根据非负简单函数积分的定义，$D(x)$ 在 $[0,1]$ 上的 Lebesgue 积分为
-\begin{equation}\label{inter2}
-  \int_0^1 D(x)dx = \int_0^1 \chi_{Q_0} (x) dx = m(Q_0) = 0
-\end{equation}
-即 $D(x)$ 在 $[0,1]$ 上是 Lebesgue 可积的并且积分值为零。但 $D(x)$ 在 $[0,1]$ 上不是 Riemann 可积的。

-\begin{theorem}[Fubini 定理]\label{thm:fubi}
-若 $f(x,y)$ 是 $\mathcal{R}^p\times\mathcal{R}^q$ 上的非负可测函数，则对几乎处处的 $x\in \mathcal{R}^p$，$f(x,y)$ 作为 $y$ 的函数是 $\mathcal{R}^q$ 上的非负可测函数，$g(x)=\int_{\mathcal{R}^q}f(x,y) dy$ 是 $\mathcal{R}^p$ 上的非负可测函数。并且
-\begin{equation}\label{eq:461}
-  \int_{\mathcal{R}^p\times\mathcal{R}^q} f(x,y) dxdy=\int_{\mathcal{R}^p}\left(\int_{\mathcal{R}^q}f(x,y)dy\right)dx.
-\end{equation}
-\end{theorem}
-
-\begin{proof}
-Let $z$ be some element of $xH \cap yH$.  Then $z = xa$ for some $a \in H$, and $z = yb$ for some $b \in H$. If $h$ is any element of $H$ then $ah \in H$ and $a^{-1}h \in H$, since $H$ is a subgroup of $G$. But $zh = x(ah)$ and $xh = z(a^{-1}h)$ for all $h \in H$. Therefore $zH \subset xH$ and $xH \subset zH$, and thus $xH = zH$.  Similarly $yH = zH$, and thus $xH = yH$, as required.
-\end{proof}
-
-
-回归分析（regression analysis) 是确定两种或两种以上变量间相互依赖的定量关系的一种统计分析方法。根据定理~\ref{thm:fubi}，其运用十分广泛，回归分析按照涉及的变量的多少，分为一元回归和多元回归分析；按照因变量的多少，可分为简单回归分析和多重回归分析；按照自变量和因变量之间的关系类型，可分为线性回归分析和非线性回归分析。

-\section{常见问题 FAQ}
-
-\begin{enumerate}[label=\arabic*).]
-  \item \textit{如何删除版本信息？}\\
-    导言区不写 \lstinline|\version{x.xx}| 即可。
-  \item \textit{如何删除日期？}\\
-    与版本 \lstinline{\version} 不同的是，导言区不写或注释 \lstinline{\date} 的话，仍然会打印出当日日期，原因是 \lstinline{\date} 有默认参数。如果不需要日期的话，日期可以留空即可，也即 \lstinline|\date{}|。
-  \item \textit{如何获得中文日期？}\\
-    为了获得中文日期，必须在中文模式下，使用 \lstinline|\date{\zhdate{2019/12/09}}|，如果需要当天的汉化日期，可以使用 \lstinline|\date{\zhtoday}|，这两个命令都来源于 \href{https://ctan.org/pkg/zhnumber}{\lstinline{zhnumber}} 宏包。
-  \item \textit{如何添加多个作者？}\\
-    在 \lstinline{\author} 里面使用 \lstinline{\and}，作者单位可以用 \lstinline{\\} 换行。
-    \begin{lstlisting}
-      \author{author 1\\ org. 1 \and author 2 \\ org. 2 }

-\section{ElegantNote Instructions}
-\thispagestyle{empty}
-\textcolor{red}{\bfseries Caution: This template will no longer be maintained since January 1st, 2023.}
-
-
-The brand new ElegantNote is redesigned on the basis of \LaTeX{} article, a more elegant note template! You can use either \hologo{pdfLaTeX} or \hologo{XeLaTeX} to compile. It is recommended that \hologo{pdfLaTeX} be used for notes in English while \hologo{XeLaTeX} be used for notes in Chinese.
-
-
-The new template has the following features:
-\begin{itemize}
-  \item two modes: good for eye mode (geye) and hazy mode;
-  \item different devices: Pad (default), Screen(beamer size), Kindle, PC (double-page) and normal (A4);
-  \item 5 color themes: \textcolor{eblue}{blue} (default),  \textcolor{egreen}{green}, \textcolor{ecyan}{cyan}, \textcolor{sakura}{sakura} and \textcolor{black}{black};
-  \item languages support: Chinese (default), English;
-  \item support \hologo{pdfLaTeX} and \hologo{XeLaTeX};
-  \item prettier captions, list environments, and unified fonts;
-  \item custmized global font size: 8pt, 9pt, 10pt, 11pt, 12pt, 14pt, 17pt and 20pt;
-  \item support for math font options for \lstinline{newtx} and \lstinline{mtpro2};
-  \item with the option of \lstinline{bibstyle} (default: apalike) for changing style of bibliography;
-  \item change the citation style with \lstinline{cite} option: \lstinline{authoryear}, \lstinline{numbers} and \lstinline{super}.
-\end{itemize}
-
-\subsection{Optional Modes}
-
-This template provides optional modes: good for eye mode (geye) and hazy mode, while the paper color is green for the former and light blue for the latter. you can use the following code to activate the desired mode:
-\begin{lstlisting}[frame=none]  
-  \documentclass[geye]{elegantnote} % or
-  \documentclass[mode=geye]{elegantnote}
-  \documentclass[hazy]{elegantnote} % or
-  \documentclass[mode=hazy]{elegantnote}
-\end{lstlisting}
-
-\begin{remark}
-  If you are expected to customize background, use:
-  \begin{lstlisting}
-    \definecolor{geyecolor}{RGB}{199,237,204}
-    \pagecolor{geyecolor}
-  \end{lstlisting}
-\end{remark}
-
-
-\subsection{Device Options}
-
-To make the notes more comfortable to read, we designed four output options (of different sizes) that correspond to different reading devices: Pad (default), Kindle, PC and A4paper. 
-
-\textcolor{red}{New}: For the convenience of notes presentation, version 2.20 offers a new option for device, i.e. \lstinline{device=screen}, which is similar to the size of MS Powerpoint with ratio aspect of 4:3 (2019/12/06).
-
-The options of output for different devices are
-\begin{lstlisting}[frame=none]  
-  \documentclass[device=pad]{elegantnote}    % ipad screen size
-  \documentclass[device=kindle]{elegantnote} % kindle screen size
-  \documentclass[device=pc]{elegantnote}     % double pages for pc 
-  \documentclass[device=normal]{elegantnote} % a4 normal page
-  \documentclass[device=screen]{elegantnote} % 4:3 PPT size
-\end{lstlisting}
-
-\begin{note}
-You can also select the device by using a direct assignment method, such as:
-\end{note}
-
-\begin{lstlisting}[frame=none]  
-  \documentclass[pad]{elegantnote}
-  \documentclass[kindle]{elegantnote}
-  \documentclass[pc]{elegantnote}
-  \documentclass[normal]{elegantnote}
-  \documentclass[screen]{elegantnote}
-\end{lstlisting}
-
-\begin{note}
-To get a normal A4paper size PDF, please select \lstinline{device=normal}.
-\end{note}
-
-\subsection{Math Fonts}
-
-This template defines a new option (\lstinline{math}), with three options:
-
-\begin{enumerate}
-  \item \lstinline{math=cm} (default), use \LaTeX{} default math font (recommended).
-  \item \lstinline{math=newtx}, use \lstinline{newtxmath} math font (may bring about bugs).
-  \item \lstinline{math=mtpro2}, use \lstinline{mtpro2} package to set math font.
-\end{enumerate}
-
-
-\subsection[Color Themes]{Color Themes\footnote{Test for chapter footnote.}}
-
-This template contains 5 color themes, \textcolor{egreen}{green}, \textcolor{ecyan}{cyan}, \textcolor{eblue}{blue}(default), \textcolor{sakura}{sakura} and \textcolor{black}{black}. If you don't need color, you can choose black theme. The color theme is enabled in the same way as before:
-\begin{lstlisting}[frame=none]  
-  \documentclass[green]{elegantnote}
-  \documentclass[color=green]{elegantnote}
-  ....
-  \documentclass[black]{elegantnote}
-  \documentclass[color=black]{elegantnote}
-\end{lstlisting}
-
-
-\subsection{Languages}
-
-This template contains two sets of language environments, changing the language environment will change the title of table/figure (figure, table), article structure words (such as the table of contents, references, etc.), and the environment Introductory words (such as Theorem, Lemma, etc.). The different language modes are enabled as follows:
-\begin{lstlisting}[frame=none]  
-  \documentclass[cn]{elegantnote}
-  \documentclass[lang=cn]{elegantnote}
-  \documentclass[en]{elegantnote}
-  \documentclass[lang=en]{elegantnote}
-\end{lstlisting}
-
-\begin{note}
-Chinese characters are allowed in Chinese mode only. To type in Chinese characters in English mode, please include \lstinline{ctex}\footnote{Please use \lstinline{scheme=plain} to retain headlines in English.} or \lstinline{xeCJK} package.
-\end{note}
-
-
-\subsection{Theorem Class Environments}
-
-This template used the \lstinline{amsthm} to create theorems, there are 4 types of theorem environments
-\begin{itemize}
-  \item \textbf{Theorem-Class}: theorem, lemma, proposition, corollary;
-  \item \textbf{Definition-Class}: definition, conjecture, example;
-  \item \textbf{Remark-Class}: remark, note, case;
-  \item \textbf{Proof-Class}: proof.
-\end{itemize}
-
-\begin{remark}
-With the option \lstinline{lang=cn} , the introductory words of the theorem class environments will be changed to Chinese.
-\end{remark}
-
-
-\section{Writing Sample}
-
-We will define the integral of a measurable function in three steps. First, we define the integral of a nonnegative simple function. Let $E$ be the measurable set in $\mathcal{R}^N$.
-
-% source: https://www.maths.tcd.ie/~dwilkins/LaTeXPrimer/Theorems.html
-
-\begin{definition}[Left Coset]
-Let $H$ be a subgroup of a group~$G$.  A \emph{left coset} of $H$ in $G$ is a subset of $G$ that is of the form $xH$, where $x \in G$ and $xH = \{ xh : h \in H \}$. Similarly a \emph{right coset} of $H$ in $G$ is a subset of $G$ that is of the form $Hx$, where $Hx = \{ hx : h \in H \}$
-\end{definition}
-
-Note that a subgroup~$H$ of a group $G$ is itself a left coset of $H$ in $G$.
-
-\begin{lemma}[Size Of Left Coset]
-Let $H$ be a finite subgroup of a group $G$.  Then each left
-coset of $H$ in $G$ has the same number of elements as $H$.
-\end{lemma}
-
-\begin{theorem}[Lagrange's Theorem]
-Let $G$ be a finite group, and let $H$ be a subgroup
-of $G$.  Then the order of $H$ divides the order of $G$.
-\end{theorem}
-
-\begin{proof}
-Let $z$ be some element of $xH \cap yH$.  Then $z = xa$ for some $a \in H$, and $z = yb$ for some $b \in H$. If $h$ is any element of $H$ then $ah \in H$ and $a^{-1}h \in H$, since $H$ is a subgroup of $G$. But $zh = x(ah)$ and $xh = z(a^{-1}h)$ for all $h \in H$. Therefore $zH \subset xH$ and $xH \subset zH$, and thus $xH = zH$.  Similarly $yH = zH$, and thus $xH = yH$, as required.
-\end{proof}

-
-Regression analysis is a powerful statistical method that allows you to examine the relationship between two or more variables of interest. While there are many types of regression analysis, at their core they all examine the influence of one or more independent variables on a dependent variable. The process of performing a regression allows you to confidently determine which factors matter most, which factors can be ignored, and how these factors influence each other.
-
-Let's continue using our application training example. In this case, we'd want to measure the historical levels of satisfaction with the events from the past three years or so, as well as any information possible in regards to the independent variables.
