您可以使用两个并排的minipage
。这还需要将整个构造括起来,\texorpdfstring
以避免书签和 PDF 信息出现问题:
\documentclass{beamer}
\usetheme{Rochester}
\title{The Title}
\author[xyz]{\texorpdfstring{%
\footnotesize
\begin{minipage}{.5\textwidth}
\centering
Final Presentation \\
submitted by \\
xyz
\end{minipage}%
\begin{minipage}{.5\textwidth}
\centering
Under the guidance of \\
xyz \\
xyz
\end{minipage}}{The Author}}
\institute[The institute]{The Institute \\ xyz}
\begin{document}
\begin{frame}
\maketitle
\end{frame}
\end{document}
