+# Easybook book document class
+Easybook is a minimalist style template based on the ctexbook book document class.  It is mainly suitable for typesetting Chinese books or notes, and can even be slightly modified to become a dissertation template.  Some commonly used macro packages have been loaded to achieve general typesetting requirements. Although some details have been considered as much as possible, there are still deficiencies.
+## Compilation method
+Please use the UTF8 encoding and enter the following command on the command line
+```
+xelatex -shell-escape easybook-demo
+bibtex easybook-demo
+makeindex easybook-demo
+xelatex -shell-escape easybook-demo
+xelatex -shell-escape easybook-demo
+```

+# easybook 书籍文档类
+
+easybook 是基于 ctexbook 书籍文档类的极简风格模板。它主要适用于中文书籍或笔记的排版，甚至可以稍作修改成为论文模板。已加载一些常用的宏程序包以实现一般的排版要求。尽管已尽可能多地考虑了一些细节，但仍然存在不足。
+## 编制方法
+请使用 UTF8 编码，并在命令行上输入以下命令

+\chapter{常用环境}
+
+\section{公式}\index{g@公式}
+\lstinline{amsmath} 宏包提供多种公式环境以及许多相关的排版命令，可用以改进和提高数学结构的排版效果。\textsf{注意，公式前不要空行。}
+\begin{equation}\label{eq1}
+  \bm{A} = \left[
+  \begin{matrix}
+    a_{11} & a_{12} & \cdots & a_{1n} \\
+    a_{21} & a_{22} & \cdots & a_{2n} \\
+    \vdots & \vdots & \ddots & \vdots \\
+    a_{m1} & a_{m2} & \cdots & a_{mn} \\
+  \end{matrix}
+  \right] = \left[
+    \begin{matrix}
+      \bm{a}_1 & \bm{a}_2 & \cdots & \bm{a}_n
+    \end{matrix}
+  \right]
+\end{equation}
+可以通过添加标签在正文中引用公式，如带有中文括号的引用\cref{eq1}。
+
+\lstinline{align} 环境用于\textsf{两个及以上}需要垂直对齐的公式，一般的像等于号之类的二元算符是被对齐的。变体的块环境 \lstinline{aligned} 使得内容的长度就是它的\textsf{实际长度}，可以用作包含表达式的组件。\lstinline{split} 环境是针对\textsf{单个长公式}，使用\& 标记对齐点。\lstinline{split} 环境不提供编号，只能在其他行间公式结构中使用。
+\begin{equation}
+  \begin{split}
+    \iint_{A}E\rho(\bm{v}\cdot\bm{n})\mathrm{d}A+\frac{\partial}{\partial t}\iiint_{V}E\rho \mathrm{d}V & = \frac{\delta Q}{\mathrm{d}t}-\frac{\delta W}{\mathrm{d}t}
+    \\
+    \iint_{A}\left(U+\frac{v^{2}}{2}+gz+\frac{P}{\rho}\right)\rho(\bm{v}\cdot\bm{n})\mathrm{d}A+\frac{\partial}{\partial t}\iiint_{V}E\rho\mathrm{d}V & = \frac{\delta Q}{\mathrm{d}t}-\frac{\delta W_{s}}{\mathrm{d}t}
+  \end{split}
+\end{equation}
+
+调用 \lstinline{cases} 括号宏包提供的左花括号 \lstinline{subnumcases} 环境，可将花括号右侧的每行公式都给出一个子序号。
+\begin{subnumcases}{y =}
+  C_1e^{r_1x}+C_2e^{r_2x} & \quad $p^2-4q > 0$
+  \\
+  \left(C_1+C_2\right)e^{r_1x} & \quad $p^2-4q=0$
+  \\
+  e^{\alpha x}\left(C_1\cos\beta x+C_2\sin\beta x\right) & \quad $p^2-4q<0$
+\end{subnumcases}
+
+\lstinline{multline} 环境适用于一行无法放下的公式。\lstinline{multline} 的第一行在最左边，最后一行在最右边，除了在两边有缩进量，中间的任何其他行都会在行间公式宽度内独立居中，例子见\cref{defi1}。
+
+\clearpage
+\section{插图}\index{c@插图}
+当我们需要排列一组子图共享标题的图片时，可以使用依赖于 \lstinline{caption} 宏包的 \lstinline{subcaption} 宏包的功能，效果见\cref{fig1}。
+\begin{figure}[htbp]
+  \centering
+  \subcaptionbox{并排子图1}
+    {\includegraphics[width=0.4\textwidth]{example-image-4x3}}
+  \hspace{1.2em}
+  \subcaptionbox{并排子图2}
+    {\includegraphics[width=0.4\textwidth]{example-image-4x3}}
+  \bicaption[使用subcaption排版子图]{使用subcaption宏包的subcaptionbox命令排版子图}[Use subcaption to typeset subgraphs]{Use the subcaptionbox command of the subcaption package to typeset sub-pictures}\label{fig1}
+\end{figure} 
+
+\section{表格}\index{b@表格}
+合并表格列使用 \lstinline{\multicolumn} 命令，合并行使用 \lstinline{\multirowcell} 命令。当插入的表格内容过长以至于一行放不下的情况可以使用 \lstinline{tabularx} 环境，设置了\textsf{L、C和R}三个列对齐选项，一个例子如\cref{tab1} 所示。
+\begin{table}[htbp]
+  \centering
+  \bicaption{使用tabularx创建内容过长表格}{Use tabularx to create a table with too long content}\label{tab1}\small
+  \begin{tabularx}{0.87\textwidth}{@{}llL@{}}
+    \toprule
+    Aliquam & Integer & Pellentesque tincidunt purus
+    vel magna. \\
+    \midrule
+    viverra & \multirowcell{3}[0ex][l]{metus} & Nulla malesuada porttitor diam. Vestibulum lectus. Proin mauris. Proin eu nunc eu urna hendrerit faucibus. \\
+    semper & & Nullam elementum, urna vel imperdiet sodales, elit ipsum pharetra ligula, ac pretium ante justo a nulla. Curabitur tristique arcu eu metus. \\
+    \multicolumn{2}{c}{\multirowcell{3}{convallis}} & Nunc elementum fermentum wisi. Aenean placerat. Ut imperdiet, enim sed gravida sollicitudin, felis odio placerat quam, ac pulvinar elit purus eget enim. \\
+    \bottomrule
+  \end{tabularx}
+\end{table}
+
+\clearpage
+\section{列表}\index{l@列表}
+\lstinline{enumitem} 宏包为系统自带的列表环境提供了更灵活的标签以及间距的控制。已设置默认格式，若自定义标签可例如
+\begin{lstlisting}[numbers = none]
+\begin{enumerate}[label = \arabic*(a),leftmargin = 1cm,resume]
+\begin{itemize}[label = \textbullet]
+\begin{description}[font = \sffamily\bfseries,style = nextline]
+\end{lstlisting}
+
+\subsection{排序列表}\label{subsec1}\index{l@列表!p@排序列表}
+\begin{enumerate}
+  \item 使用 \lstinline{enumerate} 环境可创建有序列表。
+  \item 第二项
+  \begin{enumerate}
+    \item 第二项中的第一项
+  \end{enumerate}
+\end{enumerate}
+使用 \lstinline{enumerate*} 环境产生行内部列表。可以使用\textsf{A、a、I、i和1}作为可选项为 \lstinline{enumerate*} 与 \lstinline{enumerate} 格式化标签，
+\begin{enumerate*}[(a)]
+  \item 行内第一项
+  \item 行内第二项
+\end{enumerate*}。
+若生成\textbf{Item I、Item II、Item III}格式可以这样
+\begin{lstlisting}[numbers = none]
+\begin{enumerate*}[(a)]
+\begin{enumerate}[\bfseries{Item}I]
+\end{lstlisting}
+
+\subsection{常规列表}\index{l@列表!c@常规列表}
+\begin{itemize}
+  \item 第一项 \\
+  使用 \lstinline{itemize} 环境可创建不计数列表，若换行不缩进。 \par
+  若在列表中分段后则缩进两字符。
+  \item 第二项
+  \begin{itemize}
+    \item \lstinline{itemize*} 为行内常规列表，也提供一个可选参数。
+  \end{itemize}
+\end{itemize}
+用$\star$取代默认的符号
+\begin{lstlisting}[numbers = none]
+\begin{itemize*}[$\star$]
+\begin{itemize}[$\star$]
+\end{lstlisting}
+
+\subsection{主题列表}\index{l@列表!z@主题列表}
+\begin{description}
+  \item[主题一] 使用 \lstinline{description} 环境可创建带有主题词的列表。
+  \item[主题二] 详细内容
+\end{description}
+

+\section{定理}\index{d@定理}
+\begin{theorem}[（高斯公式\footnote{选自高等数学公式。}）]\label{theo1}\index{d@定理!g@高斯公式}
+设空间闭区域$\Omega$是由分片光滑的闭曲面$\Sigma$围成，若函数$P(x,y,z)$，$Q(x,y,z)$，$R(x,y,z)$在$\Omega$上具有一节连续偏导数，则有
+\begin{align}
+  \iiint_\Omega\left(\frac{\partial P}{\partial x}+\frac{\partial Q}{\partial y}+\frac{\partial R}{\partial x}\right)\mathrm{d}V & =\oiint_\Sigma P\mathrm{d}y\mathrm{d}z+Q\mathrm{d}z\mathrm{d}x+R\mathrm{d}x\mathrm{d}y
+  \\
+  & =\oiint_\Sigma \left(P\cos\alpha+Q\cos\beta+R\cos\gamma\right)\mathrm{d}S
+\end{align}
+这里$\Sigma$是整个边界曲面$\Omega$的外侧，$\cos\alpha,\cos\beta,\cos\gamma$是$\Sigma$在点$(x,y,z)$处的法向量的方向余弦。引用这个公式如\cref{theo1}。
+\end{theorem}
+
+\begin{definition}[(Stokes formula)]\label{defi1}\index{d@定理!s@Stokes formula}
+Let $\Gamma$ be a piecewise smooth directed closed curve, $\Sigma$ is a piecewise smooth directed surface bounded by $\Gamma$, the side of $\Gamma$ and the positive direction of $\Sigma$ According to the right-hand rule, if the function $P(x,y,z)$, $Q(x,y,z)$, $R(x,y,z)$ has a first-order continuous deviation on the curve $\Sigma$ Derivative, then
+\begin{multline}
+  \iint_\Sigma\left(\frac{\partial R}{\partial y}-\frac{\partial Q}{\partial z}\right)\mathrm{d}y\mathrm{d}z+\left(\frac{\partial P}{\partial z}-\frac{\partial R}{\partial x}\right)\mathrm{d}z\mathrm{d}x+\left(\frac{\partial Q}{\partial x}-\frac{\partial P}{\partial y}\right)\mathrm{d}x\mathrm{d}y
+  \\
+  = \oint_\Gamma P\mathrm{d}x+Q\mathrm{d}y+R\mathrm{d}z
+\end{multline}
+The Stokes formula is an extension of the basic calculus formula in the case of surface integration. It is also an extension of the Green formula. This formula gives the second type of surface integral on the surface block and the second type of curve on the boundary curve  Link between points.
+\end{definition}

+\lstinline{siunitx} 宏包的 \lstinline{\num} 命令可以输出科学计数法 \num{-21x.3e5}，而 \lstinline{\SI} 命令可用来输出带有单位的量，比如 \SI{.5}{mol}。
+
+\section{化学式}\index{h@化学式}
+除了以普通公式的方式，化学式还可用 \lstinline{chemformula} 实现，无机化学式例如\ch{(NH4)2S}、\ch{[Cu(NH3)4]^2+}。
