在我的研究小组中，我们有一个推荐的论文文件，它使用\include{}命令将章节带入正文。在这些文件中，章节、部分和小节的格式工作正常，但只要我\part{}在主文档中添加或\include{}在主文档中添加，就会生成错误“未定义的控制序列”，并以奇怪的方式打印 pdf：
第一部分
24.8830ptTITLE
\part{} 在自定义类中定义，如下面的类文档所示。
这基本上是我想要的格式：
- 介绍
- 第一部分
- 第1章
- 第2章
- 第二部分
- 第3章
- 第四章
- 结论

% ****************************************
% * TABLE OF CONTENTS, ETC. *
% ****************************************
%
% A \subsection command writes a
% \contentsline{subsection}{TITLE}{PAGE}
% command on the .toc file, where TITLE contains the contents of the
% entry and PAGE is the page number. If subsections are being numbered,
% then TITLE will be of the form
% \numberline{NUM}{HEADING}
% where NUM is the number produced by \thesubsection. Other sectioning
% commands work similarly.
%
% A \caption command in a 'figure' environment writes
% \contentsline{figure}{\numberline{NUM}{CAPTION}}{PAGE}
% on the .lof file, where NUM is the number produced by \thefigure and
% CAPTION is the figure caption. It works similarly for a 'table' environment.
%
% The command \contentsline{NAME} expands to \l@NAME. So, to specify
% the table of contents, we must define \l@chapter, \l@section,
% \l@subsection, ... ; to specify the list of figures, we must define
% \l@figure; and so on. Most of these can be defined with the
% \@dottedtocline command, which works as follows.
%
% \@dottedtocline{LEVEL}{INDENT}{NUMWIDTH}{TITLE}{PAGE}
% LEVEL : An entry is produced only if LEVEL < or = value of
% 'tocdepth' counter. Note, \chapter is level 0, \section
% is level 1, etc.
% INDENT : The indentation from the outer left margin of the start of
% the contents line.
% NUMWIDTH : The width of a box in which the section number is to go,
% if TITLE includes a \numberline command.
%
% This command uses the following three parameters, which are set
% with a \def (so em's can be used to make them depend upon the font).
% \@pnumwidth : The width of a box in which the page number is put.
% \@tocrmarg : The right margin for multiple line entries. One
% wants \@tocrmarg > or = \@pnumwidth
% \@dotsep : Separation between dots, in mu units. Should be \def'd to
% a number like 2 or 1.7

\part是一个有效的类命令（的ucalgthes1.cls），并且不需要额外的包。
问题出在 thes12.clo 文件中的这一行（#67）
\newcommand{\Huge}{\fontsizelet\@xxvpt{30pt}\selectfont}
我想，应该如此
\newcommand{\Huge}{\fontsize\@xxvpt{30pt}\selectfont}
可以通过添加来解决
\renewcommand{\Huge}{\huge}回到序言。然后一切正常。
与 无关\include。

对于将来可能遇到此问题的任何人来说，问题在于该部分已在类中定义，但定义时出现了一些我无法找到的格式错误。为了解决这个问题，我使用以下命令重新定义了定义的格式，该命令放在 main.tex 文档中的命令之前\begin{document}：
\usepackage{titlesec}
\titleformat{\part}{\centering \bf \huge}{Part \thepart}{0 pt}{\newline}[\nobreak]
