示例如下：

\documentclass{article}
\usepackage{times}
\pagestyle{empty}
\setcounter{page}{6}
\setlength\textwidth{207.0pt}
\setlength\fboxrule{1pt}

\renewcommand\thesubsection
{\fbox{\thesection.\arabic{subsection}}}

\begin{document}
\setcounter{section}{3}
\subsection{A mistake}\label{wrong}
Referencing a subsection in this format
produces a funny result as we can see
looking at subsection~\ref{wrong}.
We get a boxed reference.
\end{document}

示例二：

\documentclass{article}
\pagestyle{empty}
\setcounter{page}{6}
\setlength\textwidth{207.0pt}

\makeatletter
\renewcommand\subsection{\@startsection
{subsection}{2}{0mm}%name, level, indent
{-\baselineskip}% beforeskip
{0.5\baselineskip}% afterskip
{\normalfont\normalsize\itshape}}% style
\makeatother

% redefinition of \subsection shown below
\setcounter{section}{4} % simulate previous
% sections
\begin{document}
\ldots\ some text above.
\subsection{Example of a Section Heading}
The heading is set in normal-sized italic
and the separation from the preceding text
is exactly one baseline. The separation
from the text following is one-half
baseline and this text is not indented.
\end{document}
