Question

我怎样才能在零件名称下画一条小线。我的尝试是

\part*{PART I} \addcontentsline{toc}{part}{{\huge \textbf{PART I}} \\ \hrule}

但这个失败了，下面是包含该部分的屏幕截图。提前致谢。

既然你不想，我会为你发布一个 MWE 来开始工作（編輯根据 OP 的愿望):

% My standard header for TeX.SX answers:
\documentclass[a4paper]{article} % To avoid confusion, let us explicitly 
                                 % declare the paper format.

\usepackage[T1]{fontenc}         % Not always necessary, but recommended.
% End of standard header.  What follows pertains to the problem at hand.

\usepackage{tocloft} % to center the part name
\renewcommand\cftpartpresnum{\hfill}
\renewcommand\cftpartleader{\hfill}



\begin{document}

\tableofcontents

\part{A Title}
\addtocontents{toc}{\nobreak\smallskip\hrule}

\section{Foo bar}
Some text.

\end{document}

从您的问题中无法清楚看出您是只希望在特定部分标题下设置规则，还是希望在所有部分标题下设置规则。在第二种情况下，阅读软件包的文档后tocloft，我认为可以采用一种更简单的解决方案：

% My standard header for TeX.SX answers:
\documentclass[a4paper]{article} % To avoid confusion, let us explicitly 
                                 % declare the paper format.

\usepackage[T1]{fontenc}         % Not always necessary, but recommended.
% End of standard header.  What follows pertains to the problem at hand.

\usepackage{tocloft} % to center the part name
\renewcommand*{\cftpartpresnum}  {\hfill}
\renewcommand*{\cftpartleader}   {\hfill}
\renewcommand*{\cftpartafterpnum}{\par\nobreak\smallskip\hrule}



\begin{document}

\tableofcontents

\part{A Title}

\section{Foo bar}
Some text.

\section{Biz baz}
Some text.

\part{Another Title}

\section{Yuk yuk}\
Some text.

\section{Hu-hu?}
Some text.

\end{document}
