section{Introduction}

Your introduction goes here! Some examples of commonly used commands and features are listed below, to help you get started. If you have a question, please use the help menu (``?'') on the top bar to search for help or ask us a question. 

section{Some examples to get started}

subsection{How to add Comments}

Comments can be added to your project by clicking on the comment icon in the toolbar above. % * <john.hammersley@gmail.com> 2014-09-03T09:54:16.211Z:

% Here's an example comment!

% ^ <1281561801@qq.com> 2017-02-11T06:22:46.997Z.
To reply to a comment, simply click the reply button in the lower right corner of the comment, and you can close them when you're done.

subsection{How to include Figures}

First you have to upload the image file from your computer using the upload link the project menu. Then use the includegraphics command to include it in your document. Use the figure environment and the caption command to add a number and a caption to your figure. See the code for Figure ref{fig:frog} in this section for an example.

egin{figure}
centering
includegraphics[width=0.3	extwidth]{frog.jpg}
caption{label{fig:frog}This frog was uploaded via the project menu.}
end{figure}

subsection{How to add Tables}

Use the table and tabular commands for basic tables --- see Table~ref{tab:widgets}, for example. 

egin{table}
centering
egin{tabular}{l|r}
Item & Quantity \hline
Widgets & 42 \
Gadgets & 13
end{tabular}
caption{label{tab:widgets}An example table.}
end{table}

subsection{How to write Mathematics}

LaTeX{} is great at typesetting mathematics. Let $X_1, X_2, ldots, X_n$ be a sequence of independent and identically distributed random variables with $	ext{E}[X_i] = mu$ and $	ext{Var}[X_i] = sigma^2 < infty$, and let
[S_n = frac{X_1 + X_2 + cdots + X_n}{n}
      = frac{1}{n}sum_{i}^{n} X_i]
denote their mean. Then as $n$ approaches infinity, the random variables $sqrt{n}(S_n - mu)$ converge in distribution to a normal $mathcal{N}(0, sigma^2)$.


subsection{How to create Sections and Subsections}

Use section and subsections to organize your document. Simply use the section and subsection buttons in the toolbar to create them, and we'll handle all the formatting and numbering automatically.

subsection{How to add Lists}

You can make lists with automatic numbering dots

egin{enumerate}
item Like this,
item and like this.
end{enumerate}
dots or bullet points dots
egin{itemize}
item Like this,
item and like this.
end{itemize} 

subsection{How to add Citations and a References List}

You can upload a verb|.bib| file containing your BibTeX entries, created with JabRef; or import your href{https://www.overleaf.com/blog/184}{Mendeley}, CiteULike or Zotero library as a verb|.bib| file. You can then cite entries from it, like this: cite{greenwade93}. Just remember to specify a bibliography style, as well as the filename of the verb|.bib|.

You can find a href{https://www.overleaf.com/help/97-how-to-include-a-bibliography-using-bibtex}{video tutorial here} to learn more about BibTeX.

We hope you find Overleaf useful, and please let us know if you have any feedback using the help menu above --- or use the contact form at url{https://www.overleaf.com/contact}!

1.第一个文档
打开WinEdt，建立一个新文档，将以下内容复制进入文档中，保存，保存类型选择为UTF-8。

documentclass{article}
egin{document}
hello, world
end{document}

然后在WinEdt的工具栏中找到编译按钮（在垃圾桶和字母B中间），在下拉菜单中选择XeTeX，并点击编译。如果顺利的话，我们就可以顺利生成出第一个pdf文件，点击工具栏中的放大镜按钮就可以快速打开生成的pdf文件。

2.标题、作者和注释
建立一个新文档，将以下内容复制进入文档中，保存，保存类型选择为UTF-8，编译并观察现象。

documentclass{article}
