beamer 中的 \pause 正在改变定理计数器，从而产生问题

Question

在一次演讲中，我向朋友要了一个beamer模板，他建议我使用这个模板。我照做了。我的主管建议我\pause在必要时使用，但在使用过程中，\pause我意识到定理计数器每次都会发生变化，\pause这会产生问题。我该如何修改此代码以确保不会\pause影响定理编号。这是我的演示文稿的主要代码，在代码的最后，我使用了两个章节，我正在\input{chapter1}其中\input{chapter2}编写演示文稿的主要内容。我尝试参考 TeX.SE 上的其他链接，但它不起作用。

您可以使用\resetcounteronoverlays{theoremcnt}以确保覆盖不会影响此计数器。您必须对每个自定义计数器执行相同的操作：

\documentclass[notheorems]{beamer}

\setbeamertemplate{theorem}[ams style]
\setbeamertemplate{theorems}[numbered]

\makeatletter
\newcounter{theoremcnt}
\ifbeamer@countsect
\newtheorem{theorem}[theoremcnt]{\translate{Theorem}}[section]
\else
\newtheorem{theorem}[theoremcnt]{\translate{Theorem}}
\fi
\resetcounteronoverlays{theoremcnt}


\makeatother

\mode<presentation>
{
    \usetheme{Madrid}
    \usecolortheme{rose}
    \usefonttheme{serif}
    \setbeamertemplate{}{}
    \setbeamertemplate{caption}[numbered]
}

\usepackage[english]{babel}
\usepackage{comment}
%\usepackage[utf8x]{inputenc}
\usepackage{ragged2e}
%\usepackage{epsfig}
\usepackage{mathtools}
%\usepackage{graphics}
\usepackage{xfrac}
%\usepackage{mathtools}
%\usepackage{graphicx}
%\usepackage{etoolbox}

\title[Annual Progress Seminar]{Cantor's Intersection Theorem}
\author{Rohit K}
\institute{Department of Mathematics, IIT X}
\date{30th September 2023}


\begin{document}

\begin{frame}
test
\pause
\begin{theorem}[optional title]
content...
\end{theorem}
\end{frame}

\end{document}

...或者你也可以直接使用 beamer 自己的定理。它们将自动与覆盖层配合使用：

\documentclass{beamer}

\setbeamertemplate{theorem}[ams style]
\setbeamertemplate{theorems}[numbered]

\makeatother

\mode<presentation>
{
    \usetheme{Madrid}
    \usecolortheme{rose}
    \usefonttheme{serif}
    \setbeamertemplate{}{}
    \setbeamertemplate{caption}[numbered]
}
