在我的多章节文档中，我有一些子文档，\chapter但所有子文档都使用了章节编号，只显示了章节标题。但是，目录中确实显示了编号。下面是主文档和示例章节的 MWE。它很长，所以请耐心等待，不确定我还能再写多少，但这会重现问题：

\chapter{Introduction}
The Late Neolithic (3000-2000 bce) is characterized by the spread
of the Longshan Culture Complex throughout the Huang-Huai floodplain,
covering all regions occupied by the earlier Yangshao and Dawenkou
cultures (Chang 1986; Fitzgerald-Huber 1983; Liu 2004; Liu and Chen
2006). Definition of local Longshan phases is based primarily on minor
stylistic differences in the pottery inventories of these regions,
though such stylistic criteria are limited to external, decorative
features of the pottery.
\section{Research Questions}
The developments that took place in the communities of the Luoyang
Basin between 3000 and 1500 BCE provide an excellent opportunity for
studying the emergence of the state through material culture.

编辑＃1：
在 Sora 和 Christian 的帮助下，我终于搞清楚了这一点。针对我关于将章节号和章节标题放在不同行的评论，我认为第一组代码就是为了实现这一点。它在 LyX 中有效（可能忽略了第二组代码），但在 LaTeX 中无效（可能忽略了第一组代码）。因此，我现在有：
\renewcommand{\@makechapterhead}[1]{{
\setlength{\topmargin}{0.5in}
\normalfont\large\bfseries
\begin{center}
\etchapterheadstyle{\@chapapp{~\thechapter}} % CHAP or APP #
\\
\etchapterheadstyle{#1} % TITLE OF CHAPTER
\end{center}
\setlength{\topmargin}{0in}
}}
完美的！
答案1
问题出\renewcommand{\@makechapterhead}[1]{{在原始（我们称之为有点;-)）MWE的第139行中的第二个，因为在前几行中，已经有一个\renewcommand{\@makechapterhead}[1]{{（从第129行开始）块
\etchapterheadstyle{\@chapapp{ \thechapter}} % CHAPTER 1 or APPENDIX
\etchapterheadstyle{#1} % TITLE OF CHAPTER
然而，这种明显的章节标题重复并没有效果，因为该命令完全被
\etchapterheadstyle{#1} % TITLE OF CHAPTER,
通过 仅输出章节名称，而不输出章节编号\thechapter。\@chapapp会在前面添加单词CHAPTER，因此如果不需要，请省略它。 从这个意义上讲，Sora 的解决方案确实有效，但是，他/她不知道额外的\renewcommand。
我使用 MWE 是为了减轻 OP 事后自己添加的负担，所以代码很长，但我用一些周围的文字标记了相关代码%%%%%%%%%%%%%%%%%%%%%%%

答案2
由于缺乏 MWE 并根据用法判断\etchapterheadstyle，我假设您使用的是芝加哥大学的数学论文风格或以此为基础的风格。
我尽力为您的代码构建了一个最小工作示例，并且我发现用 替换 对我来说是\chapapp可行\@chapapp的。
根据您重新定义的确切位置，您可能需要用[...]\@makechapterhead括起代码。\makeatletter\makeatother
