如何在Beamer定理环境中更改文本格式？

Question

我正在进行投影仪演示，我想在定理环境中更改文本的格式。

定理中的文本默认情况下以\textit{}或\textsl{}格式设置，但是我希望将其设置为“正常”格式，即我想将格式更改为“纯文本”。我该怎么办？

根据上一个问题的答案，您可以在定理块的定义中添加\normalfont：

\documentclass{beamer}

\usetheme{Aalborg}

\uselanguage{danish}
\languagepath{danish}
\deftranslation[to=danish]{Theorem}{Saetning}

\makeatletter
\setbeamertemplate{theorem begin}{%
  \setbeamercolor{block title}{bg=cyan!100!white}%
  \setbeamercolor{itemize item}{fg=cyan!100!white}%
  \setbeamercolor{itemize subitem}{fg=cyan!100!white}%
  \setbeamercolor{itemize subsubitem}{fg=cyan!100!white}%
  \setbeamercolor{enumerate item}{fg=cyan!100!black}%
  \setbeamercolor{enumerate subitem}{fg=cyan!100!black}%
  \setbeamercolor{enumerate subsubitem}{fg=cyan!100!black}%
  \begin{\inserttheoremblockenv}
    {%
      \inserttheoremname
      \inserttheoremnumber
      \ifx\inserttheoremaddition\@empty\else\ \inserttheoremaddition\fi%
    }%
    \normalfont%
}

\setbeamertemplate{theorem end}{%
    \end{\inserttheoremblockenv}%
}

\makeatother

\begin{document}

\begin{frame}
    \begin{theorem}[Pythagoras]
            text
        $a^2+b^2=c^2$ 
        \begin{itemize}
        \item test
        \end{itemize}
        \label{pytagoras}
    \end{theorem}

    Theorem \ref{pytagoras}

    \begin{block}{Title Pythagoras}
        content...
        \begin{itemize}
        \item test
        \end{itemize}
    \end{block}
\end{frame}
