\documentclass[12pt, letterpaper]{article}
% 声明文档类型,不同类型的文档需要不同的类,12pt设置字体大小,letterpaper设置纸张大小
% 序言部分
% 定义文档类型,加载包
% \usepackage[options]{somepackage}
\usepackage{graphicx} % graphicx包提供导入图片功能
\graphicspath{{images/}} % 图片保存在名为images的文件夹中,该文件夹包含在当前目录中
\title{My first LaTeX document}
\author{Hubert Farnsworth\thanks{Funded by the Overleaf team.}} % \thanks致谢机构
\date{August 2022} % 可以手动键入日期,也可以 \date{\today}
\begin{document}
\maketitle %排版标题、作者和日期
\tableofcontents % 生成目录
\begin{abstract}
This is a simple paragraph at the beginning of the
document. A brief introduction about the main subject.
\end{abstract}
% 摘要
First document. This is a simple example, with no extra parameters or packages included.
Some of the \textbf{greatest} % \textbf{...} 粗体
discoveries in \underline{science} % \underline{...} 下划线
were made by \textbf{\textit{accident}}. % \textit{...} 斜体 可以嵌套使用
% \emph{argument} 也是强调的命令
\includegraphics{universe} % 导入图片,只需要文件名不需要拓展名
\begin{figure}[h]
\centering
\includegraphics[width=0.75\textwidth]{mesh} % 将图形的宽度设置为文本宽度的75%,mesh为文件名
\caption{A nice plot.} % 设置图形标题，可以放在图形的上方或下方
\label{fig:mesh1} % 要在文档中引用此图像,可以使用\label命令为其添加标签,该标签用于为图像生成一个数字
\end{figure}
As you can see in figure \ref{fig:mesh1}, the function grows near the origin. This example is on page \pageref{fig:mesh1}. % \ref{fig:mesh1}:此代码将替换为与参考图形对应的数字
