您可以通过以下方式控制方形枚举项的字体大小\setbeamerfont{item projected}{size=\huge}
:
\documentclass{beamer}
\usecolortheme{whale}
\useinnertheme{rectangles}
\begin{document}
\section{References}
\begin{frame}
\setbeamerfont{itemize/enumerate body}{size=\huge}
\setbeamerfont{item projected}{size=\huge}
\begin{enumerate}
\addtocounter{enumi}{4}
\item References
\end{enumerate}
\end{frame}
\end{document}
从外观上看,您正在尝试手动创建某种部分页面?如果是,那么让 beamer 为您完成这项工作会更容易:
\documentclass{beamer}
\usecolortheme{whale}
\useinnertheme{rectangles}
\setbeamertemplate{section page}{
\huge
{\color{structure.fg}
\vrule width2.25ex height1.85ex depth.4ex}%
\hskip-2.25ex%
\hbox to2.25ex{%
\hfil%
\color{white}\insertsectionnumber%
\hfil}%
\space
\insertsectionhead
}
\AtBeginSection[]{
\begin{frame}
\sectionpage
\end{frame}
}
\begin{document}
\section{References}
\begin{frame}
test
\end{frame}
\end{document}
