\chapter{引言}
\label{chap:introduction}

本章说明论文研究的问题及其意义。信息论的基本概念见文献~\cite{shannon1948}。
This chapter states the problem and the plan of the thesis.

\section{研究内容}

列出本文要回答的两到三个问题。

\chapter{方法}
\label{chap:method}

\section{模型}

设离散信源有 $n$ 个符号，其概率为 $p_1, \dots, p_n$，则信源的熵为
\begin{equation}
  H = -\sum_{i=1}^{n} p_i \log_2 p_i ,
  \label{eq:entropy}
\end{equation}
当各符号等概率时熵最大。

\section{数据}

表~\ref{tab:data} 列出了实验所用的三个数据集。

\begin{table}[htbp]

  \caption{实验数据集}
  \label{tab:data}
  \begin{tabular}{lrr}
    \hline
    数据集 & 样本数 & 符号数 \\
    \hline
    A & 1200 & 4 \\
    B & 3500 & 8 \\
    C & 9800 & 16 \\
    \hline
  \end{tabular}
\end{table}

\chapter{结果与结论}
\label{chap:results}

图~\ref{fig:entropy} 给出二元信源的熵随概率 $p$ 的变化，在 $p = 0.5$ 时取最大值 1 比特，与式~(\ref{eq:entropy}) 一致。

    \draw[->] (0,0) -- (1.1,0) node[right] {$p$};
    \draw[->] (0,0) -- (0,1.15) node[above] {$H(p)$};
    \foreach \t in {0.5,1} \draw (\t,0) -- (\t,-0.03) node[below] {\t};
    \draw[thick,domain=0.01:0.99,samples=60] plot (\x, {-\x*log2(\x)-(1-\x)*log2(1-\x)});
