Latex 如何在beamer定理环境中更改文本格式？

我正在做一个beamer演示，我想在定理环境中更改文本的格式

---

定理中的文本默认格式为

\textit{}

或

\textsl{}

，但我希望其格式为“正常”，即我希望将格式更改为“纯文本”。如何才能做到这一点？

根据对上一个问题的回答，您可以将

\normalfont

添加到定理块的定义中：

\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
