latex 常用插入图片语句

导言区需要加入

\usepackage{graphicx}

\numberwithin{figure}{section}%按章节标注

\usepackage{subfigure}

\usepackage{caption}

一般正常的插图

\begin{figure}[h]%插在正文此处

    \centering%图片居中

    \includegraphics[width=0.5\textwidth]{./fig/bridge_model}%工作目录下，fig文件夹里图片

    \caption{mechanical model of a design domain}%文中标题

    \label{fig:bridge_model}%图片引用标签

\end{figure}

需要加入横列子图

\begin{figure}[h]

    \subfigure[optimization process]{%子图1

        \centering

        \includegraphics[width=6cm]{./fig/bridge_optimized}

        \label{fig:bridge_optimized}%子图1标签

    }

    \hspace{0.2in}%横列子图之间距离

    \subfigure[Zhaozhou Bridge]{ %子图2

        \centering

        \includegraphics[width=6cm]{./fig/zhaozhou_bridge}

    \label{fig:Zhaozhou_Bridge}%子图2标签

    }

    \label{fig:real and design}%总图标签

\end{figure}

需要加入纵列子图

\begin{figure}[h]

    \centering%相比于横列，多了个居中命令

    \subfigure[optimization process]{%子图1

        \centering

        \includegraphics[width=6cm]{./fig/bridge_optimized}

        \label{fig:bridge_optimized}%子图1标签

    }%关键！！！相比于横列，下一行从\hspace{}变成了空行

    \subfigure[Zhaozhou Bridge]{ %子图2

        \centering

        \includegraphics[width=6cm]{./fig/zhaozhou_bridge}

    \label{fig:Zhaozhou_Bridge}%子图2标签
