\chapter*{Abstract}
Here goes the Abstract in English of your thesis followed by a list of keywords.
The Abstract is a concise summary of the content of the thesis (single page of text)
and a guide to the most important contributions included in your thesis.
The Abstract is the very last thing you write.
It should be a self-contained text and should be clear to someone who hasn't (yet) read the whole manuscript.
The Abstract should contain the answers to the main scientific questions that have been addressed in your thesis.
It needs to summarize the adopted motivations and the adopted methodological approach as well as the findings of your work and their relevance and impact.
The Abstract is the part appearing in the record of your thesis inside POLITesi,
the Digital Archive of PhD and Master Theses (Laurea Magistrale) of Politecnico di Milano.
The Abstract will be followed by a list of four to six keywords.
Keywords are a tool to help indexers and search engines to find relevant documents.
To be relevant and effective, keywords must be chosen carefully.
They should represent the content of your work and be specific to your field or sub-field.
Keywords may be a single word or two to four words.

% In the main text of your thesis you can write the chapters in two different ways:
%
%(1) As presented in this template you can write:
% \chapter{Title of the chapter}
% *body of the chapter*
%
%(2) You can write your chapter in a separated .tex file and then include it in the main file with the following command:
% \chapter{Title of the chapter}
% \input{chapter_file.tex}
%

\chapter*{Introduction}
This document is intended to be both an example of the Polimi \LaTeX{} template for Master Theses,
as well as a short introduction to its use. It is not intended to be a general introduction to \LaTeX{} itself,
and the reader is assumed to be familiar with the basics of creating and compiling \LaTeX{} documents (see \cite{oetiker1995not, kottwitz2015latex}).
\\
The cover page of the thesis must contain all the relevant information:
title of the thesis, name of the Study Programme and School, name of the author,
student ID number, name of the supervisor, name(s) of the co-supervisor(s) (if any), academic year.
The above information are provided by filling all the entries in the command \verb|\puttitle{}|
in the title page section of this template.
\\
Be sure to select a title that is meaningful.
It should contain important keywords to be identified by indexer.
Keep the title as concise as possible and comprehensible even to people who are not experts in your field.
The title has to be chosen at the end of your work so that it accurately captures the main subject of the manuscript.
\\
Since a thesis might be a substantial document, it is convenient to break it into chapters.
You can create a new chapter as done in this template by simply using the following command
\begin{verbatim}
\chapter{Title of the chapter}
\end{verbatim}
followed by the body text.
\\
Especially for long manuscripts, it is recommended to give each chapter its own file.
In this case, you write your chapter in a separated \verb|chapter_n.tex| file
and then include it in the main file with the following command
\begin{verbatim}
\input{chapter_n.tex}
\end{verbatim}
It is recommended to give a label to each chapter by using the command
\begin{verbatim}
\label{ch:chapter_name}%
\end{verbatim}
where the argument is just a text string that you'll use to reference that part
as follows: \textit{Chapter~\ref{ch:chapter_one} contains \sc{an introduction to} \dots}.\\
If necessary, an unnumbered chapter can be created by
\begin{verbatim}
\chapter*{Title of the unnumbered chapter}
\end{verbatim}
\chapter{Chapter one}
\label{ch:chapter_one}%
% The \label{...}% enables to remove the small indentation that is generated, always leave the % symbol.
In this chapter additional useful information are reported.
\section{Sections and subsections}
\label{sec:section_name}
Chapters are typically subdivided into sections and subsections, and, optionally,
subsubsections, paragraphs and subparagraphs.
All can have a title, but only sections and subsections are numbered.
A new section is created by the command
\begin{verbatim}
\section{Title of the section}
\end{verbatim}
The numbering can be turned off by using \verb|\section*{}|.
\\
A new subsection is created by the command
\begin{verbatim}
\subsection{Title of the subsection}
\end{verbatim}
and, similarly, the numbering can be turned off by adding an asterisk as follows
\begin{verbatim}
\subsection*{}
\end{verbatim}
\section{Equations}
\label{sec:eqs}
This section gives some examples of writing mathematical equations in your thesis.
Maxwell's equations read:
\begin{subequations}
\label{eq:maxwell}
\begin{align}[left=\empheqlbrace]
\nabla\cdot \bm{D} & = \rho, \label{eq:maxwell1} \\
\nabla \times \bm{E} + \frac{\partial \bm{B}}{\partial t} & = \bm{0}, \label{eq:maxwell2} \\
\nabla\cdot \bm{B} & = 0, \label{eq:maxwell3} \\
\nabla \times \bm{H} - \frac{\partial \bm{D}}{\partial t} &= \bm{J}. \label{eq:maxwell4}
\end{align}
\end{subequations}
Equation~\eqref{eq:maxwell} is automatically labeled by \texttt{cleveref},
as well as Equation~\eqref{eq:maxwell1} and Equation~\eqref{eq:maxwell3}.
Thanks to the \verb|cleveref| package, there is no need to use \verb|\eqref|.
Remember that Equations have to be numbered only if they are referenced in the text.
Equations~\eqref{eq:maxwell_multilabels1}, \eqref{eq:maxwell_multilabels2}, \eqref{eq:maxwell_multilabels3}, and \eqref{eq:maxwell_multilabels4} show again Maxwell's equations without brace:
\begin{align}
\nabla\cdot \bm{D} & = \rho, \label{eq:maxwell_multilabels1} \\
\nabla \times \bm{E} + \frac{\partial \bm{B}}{\partial t} &= \bm{0}, \label{eq:maxwell_multilabels2} \\
\nabla\cdot \bm{B} & = 0, \label{eq:maxwell_multilabels3} \\
\nabla \times \bm{H} - \frac{\partial \bm{D}}{\partial t} &= \bm{J} \label{eq:maxwell_multilabels4}.
\end{align}
Equation~\eqref{eq:maxwell_singlelabel} is the same as before,
but with just one label:
\begin{equation}
\label{eq:maxwell_singlelabel}
\left\{
\begin{aligned}
\nabla\cdot \bm{D} & = \rho, \\
\nabla \times \bm{E} + \frac{\partial \bm{B}}{\partial t} &= \bm{0},\\
\nabla\cdot \bm{B} & = 0, \\
\nabla \times \bm{H} - \frac{\partial \bm{D}}{\partial t} &= \bm{J}.
\end{aligned}
\right.
\end{equation}
\section{Figures, Tables and Algorithms}
Figures, Tables and Algorithms have to contain a Caption that describe their content, and have to be properly reffered in the text.
\subsection{Figures}
\label{subsec:figures}
For including pictures in your text you can use \texttt{TikZ} for high-quality hand-made figures,
or just include them as usual with the command
\begin{verbatim}
\includegraphics[options]{filename.xxx}
\end{verbatim}
Here xxx is the correct format, e.g. \verb|.png|, \verb|.jpg|, \verb|.eps|, \dots.
\begin{figure}[H]
\centering
\includegraphics[width=0.3\textwidth]{logo_polimi_scritta.eps}
\caption{Caption of the Figure to appear in the List of Figures.}
\label{fig:quadtree}
\end{figure}
Thanks to the \texttt{\textbackslash subfloat} command, a single figure, such as Figure~\ref{fig:quadtree},
can contain multiple sub-figures with their own caption and label, e.g. \color{black} Figure~\ref{fig:polimi_logo1} and Figure~\ref{fig:polimi_logo2}.
\begin{figure}[H]
\centering
\subfloat[One PoliMi logo.\label{fig:polimi_logo1}]{
\includegraphics[scale=0.5]{Images/logo_polimi_scritta.eps}
}
\quad
\subfloat[Another one PoliMi logo.\label{fig:polimi_logo2}]{
\includegraphics[scale=0.5]{Images/logo_polimi_scritta2.eps}
}
\caption[Shorter caption]{This is a very long caption you don't want to appear in the List of Figures.}
\label{fig:quadtree2}
\end{figure}
\subsection{Algorithms}
\label{subsec:algorithms}
Pseudo-algorithms can be written in \LaTeX{} with the \texttt{algorithm} and \texttt{algorithmic} packages.
An example is shown in Algorithm~\ref{alg:var}.
\begin{algorithm}[H]
\label{alg:example}
\caption{Name of the Algorithm}
\label{alg:var}
\label{protocol1}
\begin{algorithmic}[1]
\STATE Initial instructions
\FOR{$for-condition$}
\STATE{Some instructions}
\IF{$if-condition$}
\STATE{Some other instructions}
\ENDIF
\ENDFOR
\WHILE{$while-condition$}
\STATE{Some further instructions}
\ENDWHILE
\STATE Final instructions
\end{algorithmic}
\end{algorithm}
\vspace{5mm}
\section{Theorems, propositions and lists}
\chapter{Conclusions and future developments}
\label{ch:conclusions}%
A final chapter containing the main conclusions of your research/study
and possible future developments of your work have to be inserted in this chapter.

\appendix
\chapter{Appendix A}
If you need to include an appendix to support the research in your thesis, you can place it at the end of the manuscript.
An appendix contains supplementary material (figures, tables, data, codes, mathematical proofs, surveys, \dots)
which supplement the main results contained in the previous chapters.
\chapter{Appendix B}
It may be necessary to include another appendix to better organize the presentation of supplementary material.

使用相同的文件，但现在使用
\usepackage{notoccite}
\usepackage[skip=0pt plus 2pt]{parskip}
baselineskip已获得 TOC 的权利。
使用的版本
notoccite.sty 2000/07/20
parskip.sty 2021-03-14 v2.0h non-zero parskip adjustments
摘自上一篇简要手册：
使用包选项
skip可以明确指定段落之间的垂直间距。如果没有给出该选项（或给出时没有值），则.5\baselineskip plus 2pt假定为拉伸。
但是使用\usepackage[skip=0pt plus 2pt]{parskip}此默认的 parskip 保留在文档内部（？）。
最后说明：在notoccitepresent 之前parskip 发出消息
Couldn't patch \@starttoc
答案2
的唯一目的notoccite是注入\@fileswfalse。\@starttoc但实际情况是，parskip想要修补\@starttoc却无法修补，因为notoccite已经改变了定义。
您可以notoccite通过以下方式添加自己的功能
\usepackage{etoolbox}
并且在序言的设置部分，加载所有包后，
\makeatletter
\patchcmd{\@starttoc}{\begingroup}{\begingroup\@fileswfalse}{}{}
\makeatother
另一方面，按出现顺序引用似乎不是一个很好的策略，因为读者想要浏览参考文献；出现的顺序使得寻找某些引用变得非常尴尬。
你真的希望“控制论者”在阅读你的论文时遇到困难吗？我会再三考虑。
当然，您都不应该使用parskip其中任何一种，尤其是在使用双倍行距时。
