投影机中的定理编号

投影机中的定理编号

我为不同的讲座幻灯片准备了单独的 tex 文件。我试图按讲座编号对我的定理进行编号。我使用以下内容:

\setbeamertemplate{theorems}[numbered]

但每个讲座文件都是从 1、2 开始。我想要

1.1,1.2,… 为讲座 1

2.1,2.2,…第 2 讲

等等

有没有办法做到这一点?

\documentclass[]{beamer} 
\usetheme{CambridgeUS} 
\setbeamertemplate{theorems}[numbered] 
\newtheorem{remark}{Remark} %for remarks 

\begin{document} 
\section{First section} 
\begin{frame} 
\frametitle{Theorems} 
\begin{theorem} 
    This is theorem 1. 
\end{theorem} 
\begin{theorem} 
    This is theorem 2. 
\end{theorem} 
\end{frame} 
\end{document}

\lecture对每个讲座 使用该命令(请参阅beamer手册第10.4 将课程拆分为讲座),然后添加

\renewcommand\thetheorem{\arabic{lecture}.\arabic{theorem}}
\makeatletter
\@addtoreset{theorem}{lecture}
\makeatother

到文档的序言部分。这将为定理和其他预定义的定理类结构产生所需的结果;对于新用户定义的结构(例如示例中的注释),您将需要一组类似的命令:

\renewcommand\theremark{\arabic{lecture}.\arabic{remark}}
\makeatletter
\@addtoreset{remark}{lecture}
\makeatother

完整示例:

\documentclass[]{beamer} 
\usetheme{CambridgeUS} 

\setbeamertemplate{theorems}[numbered] 
\newtheorem{remark}{Remark} %for remark 

\renewcommand\thetheorem{\arabic{lecture}.\arabic{theorem}}
\renewcommand\theremark{\arabic{lecture}.\arabic{remark}}
\makeatletter
\@addtoreset{theorem}{lecture}
\@addtoreset{remark}{lecture}
\makeatother


\begin{document} 

\lecture{Test lecture one}{lone}
\section{First section of lecture one} 
\begin{frame} 
\frametitle{Theorems} 
\begin{theorem} This is theorem 1. \end{theorem} 
\begin{theorem} This is theorem 2. \end{theorem} 
\begin{corollary} This is a test corollary \end{corollary} 
\begin{remark} This is a test remark \end{remark} 
\end{frame} 

\lecture{Test lecture two}{ltwo}
\section{First section of lecture two} 
\begin{frame} 
\frametitle{Theorems} 
\begin{theorem} This is theorem 1. \end{theorem} 
\begin{theorem} This is theorem 2. \end{theorem} 
\begin{corollary} This is a test corollary \end{corollary} 
\begin{remark} This is a test remark \end{remark} 
\end{frame} 

\end{document}

结果显示了两个讲座的编号:
