具有长描述性标题的章节

Question

我有一份文件，要求章节标题由两部分组成：(1) 章节编号（第 1 章、第一章等）或具有类似功能的任何其他文本，以及 (2) 编号下方的描述性标题，该标题可以很长。我能够将描述性标题放在章节编号下方，并使用以下宏根据我的需求设置其样式：

\documentclass[final]{book}
\usepackage{lipsum}

\def \mylongchapter#1#2{
\chapter*{\centering{\LARGE #1} \\* \textnormal{\Large #2}}
\addcontentsline{toc}{chapter}{#1: #2}
}

\begin{document}

\mylongchapter{Chapter 1}{This Chapter Have Very Interesting and Long Title Below Chapter Number}

\lipsum[11-30]

\end{document} 

由此产生了如下结果：

问题：

1. 有没有比我做得更好的方法来排版具有这种描述性标题的章节？
2. 如何控制（或消除）两行或多行描述性标题之间的间距/间隙（见下图）？
3. 如何控制间距第1章和描述性标题？

Answer 1

您可以尝试@makechapterhead在书籍类别中重新定义：

\documentclass[final]{book}
\usepackage{lipsum}

%\def \mylongchapter#1#2{
%\chapter*{\centering{\LARGE #1} \\* \textnormal{\Large #2}}
%\addcontentsline{toc}{chapter}{#1: #2}
%}

\makeatletter
\def\@makechapterhead#1{%
  \vspace*{50\p@}% margin above chapter number
  {\parindent \z@ \centering \normalfont
    \ifnum \c@secnumdepth >\m@ne
      \if@mainmatter
        \LARGE\bfseries \@chapapp\space \thechapter
        \par\nobreak
        \vskip 20\p@% space between chapter number and chapter title
      \fi
    \fi
    \interlinepenalty\@M
    \Large \mdseries \centering #1 \par\nobreak
    \vskip 40 \p@% space below chapter title
  }}
\makeatother
\begin{document}

%\mylongchapter{Chapter 1}{This Chapter Have Very Interesting and Long Title Below Chapter Number}
\chapter{This Chapter Have Very Interesting and Long Title Below Chapter Number}
\lipsum[11-30]

\end{document}

您可以更改三个数值（50\p@、20\p@和40 \p@）来分别调整章节号上方的边距、章节号和章节标题之间的间距以及章节标题下方的间距。请参阅代码中的注释，了解更改这些值的适当位置。

编辑：您可以使用setspace包来改变间距，如下所示：

\documentclass[final]{book}
\usepackage{lipsum}
\usepackage{setspace} %<========== package to adjust spacing
%\def \mylongchapter#1#2{
%\chapter*{\centering{\LARGE #1} \\* \textnormal{\Large #2}}
%\addcontentsline{toc}{chapter}{#1: #2}
%}

\makeatletter
\def\@makechapterhead#1{%
  \vspace*{50\p@}% margin above chapter number
  {\parindent \z@ \centering \normalfont
    \ifnum \c@secnumdepth >\m@ne
      \if@mainmatter
        \LARGE\bfseries \@chapapp\space \thechapter
        \par\nobreak
        \vskip 20\p@% space between chapter number and chapter title
      \fi
    \fi
    \interlinepenalty\@M
    \Large \mdseries \centering \onehalfspacing #1 \par\nobreak %<========== Add \doublespacing or \onehalfspacing or \singlespacing here
    \vskip 40 \p@% space below chapter title
  }}
\makeatother
\begin{document}

%\mylongchapter{Chapter 1}{This Chapter Have Very Interesting and Long Title Below Chapter Number}
\chapter{This Chapter Have Very Interesting and Long Title Below Chapter Number}
\lipsum[11-30]

\end{document}

对于\chapter*，我认为重新定义@makeschapterhead（注意星号中的“s”）会产生同样的作用。但我怀疑您可以使用其他答案中提到的某个包进行所有这些更改，甚至可能更轻松！

Answer 2

您可能想要检查该sectsty包及其\chapterfont宏。

\documentclass[final]{book}
\usepackage{lipsum,sectsty}
\chapterfont{\nohang\centering\mdseries}
\begin{document}
\chapter[Long-Titled Chapter Header]{A Very Interesting and Long Title Below the Chapter Number}
\lipsum[1-3]
\end{document} 

Answer 3

您可以完全控制该titlesec/titleps包：

\documentclass[11pt, final]{book}
\usepackage[utf8]{inputenc}
\usepackage{fourier, heuristica}
\usepackage{ifthen}
\usepackage{lipsum}

\usepackage{setspace}
\usepackage[clearempty, toctitles, newlinetospace, pagestyles]{titlesec}%explicit,
\titleformat{\chapter}[display]{\centering}{\LARGE\bfseries\chaptername~\thechapter}{1\baselineskip} {\onehalfspacing\Large}[\thispagestyle{basic}]
\titlespacing{\chapter}{0pt}{-2\baselineskip}{6\baselineskip}

\setheadrule{3pt}
\newpagestyle{basic}{%
\setfoot{}{\thepage}{}}

\renewpagestyle{plain}{%
\widenhead[1.5em][0pt]{0pt}{1.5em}
%\ifthechapter{\setheadrule{0pt}}{\setheadrule{0.4pt}}
\headrule
\sethead[][\small\scshape\chaptertitle][]{}{\small\itshape\sectiontitle}{}
\setfoot{}{\thepage}{}
\headrule
}
\pagestyle{plain}
\begin{document}

\chapter{This Chapter Has a Very Interesting and Long Title Below Chapter Number}

\section{First Section}
\lipsum[1-5]

\section{Second Section}
\lipsum[6-10]

\end{document} 

\documentclass[11pt, final]{book}
\usepackage[utf8]{inputenc}
\usepackage{fourier, heuristica}
\usepackage{ifthen}
\usepackage{lipsum}

\usepackage{setspace}
\usepackage[clearempty, toctitles, newlinetospace, pagestyles]{titlesec}%explicit,
\titleformat{\chapter}[display]{\centering}{\LARGE\bfseries\chaptername~\thechapter}{1\baselineskip} {\onehalfspacing\Large}[\thispagestyle{basic}]
\titlespacing{\chapter}{0pt}{-2\baselineskip}{6\baselineskip}

\setheadrule{3pt}
\newpagestyle{basic}{%
\setfoot{}{\thepage}{}}

\renewpagestyle{plain}{%
\widenhead[1.5em][0pt]{0pt}{1.5em}
%\ifthechapter{\setheadrule{0pt}}{\setheadrule{0.4pt}}
\headrule
\sethead[][\small\scshape\chaptertitle][]{}{\small\itshape\sectiontitle}{}
\setfoot{}{\thepage}{}
\headrule
}
\pagestyle{plain}
\begin{document}

\chapter{This Chapter Has a Very Interesting and Long Title Below Chapter Number}

\section{First Section}
\lipsum[1-5]

\section{Second Section}
\lipsum[6-10]
