问题如下：定理的编号如下：1.0.3，其中 1（章节）。0（节）3.（此节中对象的编号）。我想修改 .cls 模板，使该节从 1 开始计数，而不是从 0 开始。我该如何修复此问题，这意味着我必须在此模板中进行哪些更改？感谢您的帮助
数学
答案1
如果您在没有章节的章节中使用定理编号 1.1.1、1.1.2 等，可能会非常混乱。我建议您将此类章节的定理计数器重置为较低的级别，例如 1.1、1.2 等。
我看不到定理定义在哪里，但假设它与amsthm包中。参见下面的代码
编辑1：移动\setthmtochpand至命令\setthmtosec之前\chapter
\documentclass{report}
\usepackage{amsmath,amsthm}
\usepackage{remreset}
\newtheorem{thm}{Theorem}[section]
\renewcommand\thethm{\thesection.\arabic{thm}}
\makeatletter
\newcommand\setthmtochp{%
\@removefromreset{thm}{chapter}% just in case ... (no harm done)
\@removefromreset{thm}{section}%
\@addtoreset{thm}{chapter}%
\renewcommand\thethm{\thechapter.\arabic{thm}}}
\newcommand\setthmtosec{%
\@removefromreset{thm}{chapter}%
\@removefromreset{thm}{section}% just in case ... (no harm done)
\@addtoreset{thm}{section}%
\renewcommand\thethm{\thesection.\arabic{thm}}}
\makeatother

我发现它\@removefromreset已经在你的课程中定义了，你可能不需要这个remreset包。
