Question

请问如何更改像这张照片这样的章节格式？

\documentclass{book}
\usepackage{titlesec}
\usepackage[tracking=true]{microtype}
\usepackage{lipsum}% juts to generate text for the example

\titleformat{\chapter}[display]
{\bfseries\Large}
{\filright\MakeUppercase{\chaptertitlename} \Huge\thechapter}
{4ex}
{\titlerule
\vspace{2ex}%
\filright}
[\vspace{2ex}%
\titlerule]

\begin{document}

\chapter{Introduction}
\lipsum[4]

\end{document}

Answer 1

像这样吗？

显然，您可能希望调整大小等。我假设您的章节数可能是两位数，并且无论如何，右侧的行和标题都应占用相同的宽度。如果您的章节数少于 10 个，您可以考虑在计算相关宽度的代码中更改99为。9

请注意，尽管和朋友很受欢迎，但我个人还是很反感的，titlesec我自己也不太可能使用这种方法。所以你提供 MWE 是件好事，否则我可能会给你不兼容的代码，并给你带来各种麻烦！

\documentclass{book}
\usepackage{titlesec,calc}
\usepackage[tracking=true]{microtype}
\usepackage{lipsum}% juts to generate text for the example

\AtBeginDocument{%
  \newlength\chaptertitlenamewidth
  \newlength\chapternumberwidth
  \newlength\chapternumberheight
  \newlength\chaptertitlenameheight
  \newlength\chaptertitlenameraise
  \newlength\chaptertitlewidth
  \newsavebox{\chaptertitlenamebox}%
  \sbox\chaptertitlenamebox{\bfseries\MakeUppercase{\chaptertitlename}}%
  \settowidth{\chaptertitlenamewidth}{\usebox{\chaptertitlenamebox}}%
  \settototalheight{\chaptertitlenameheight}{\usebox{\chaptertitlenamebox}}%
  \settowidth{\chapternumberwidth}{\bfseries\Huge 99}%
  \settototalheight{\chapternumberheight}{\bfseries\Huge 99}%
  \setlength{\chaptertitlenameraise}{\chapternumberheight-\chaptertitlenameheight}%
  \setlength{\chaptertitlewidth}{\textwidth-\chaptertitlenamewidth-\chapternumberwidth-.5em}%
}

\titleformat{\chapter}[block]{\bfseries}{\raisebox{\chaptertitlenameraise}{\usebox{\chaptertitlenamebox}}\hskip .25em\begin{minipage}[b]{\chapternumberwidth}\filcenter\Huge\thechapter\end{minipage}}{0pt}{%
  \hskip .25em\begin{minipage}[b]{\chaptertitlewidth}\titlerule[1pt]\vspace{2ex}%
  }[\end{minipage}]

\begin{document}

\chapter{Introduction}
\lipsum[4]

\end{document}

Answer 2

我建议使用这个方案：

\documentclass{book}
\usepackage[explicit]{titlesec}
\usepackage{graphicx} \usepackage[tracking=true]{microtype}
\usepackage{lipsum}% just to generate text for the example

 \titleformat{\chapter}[block]
{\SetTracking[no ligatures = {f}]{encoding = *}{40}}%
{\filright\sffamily\parbox[b][1.6cm][t]{3.5cm}{\MakeUppercase{\large\lsstyle\chaptertitlename} \raisebox{-0.75\height}{\resizebox{!}{1.6cm}{\Huge\thechapter}}}}
{0ex}%
{\parbox[b][1.6cm]{\dimexpr\linewidth-3.5cm-1.6pt\relax}{\titlerule[1.5pt] \vspace{2ex}\vfill\endgraf\filright\bfseries\Large#1}}

\begin{document}

\chapter{Une courte \\Introduction}
\lipsum[4]

\end{document}
