字体大小改变后，第一项的基线跳过不同

Question

我无法在以下代码中为每个项目获取相同的类似基本跳过。

\documentclass{beamer}

\begin{document}

\begin{frame}
  \frametitle{XYZ}
    \begin{itemize}
      {\fontsize{18pt}{30}\selectfont
      \item n is the number of states; 
      \item i is the start state.
      \item j is one of the final states.
      }
  \end{itemize}
\end{frame}
\end{document}

Answer 1

不要将字体更改括在括号中（itemize无论如何都会提供它们）：

\documentclass{beamer}

\begin{document}

\begin{frame}
  \frametitle{XYZ}
    \begin{itemize}
      \fontsize{18pt}{30}\selectfont
      \item n is the number of states;
      \item i is the start state.
      \item j is one of the final states.
      \end{itemize}
\end{frame}
\end{document}
