这是一个最小工作示例：
\documentclass[10pt]{beamer}
\usepackage[framemethod=tikz,nobreak]{mdframed}
\mdtheorem[innerlinewidth=0.5pt, %
roundcorner=4pt,linecolor=blue,innerleftmargin=16pt,
innerrightmargin=16pt,backgroundcolor=white, %
frametitlerule=true,frametitlebackgroundcolor=cyan,innertopmargin=\topskip,innerbottommargin=\topskip]{definizione}{Definizione}
\begin{document}
\begin{frame}{A slide}
\begin{definizione}[A definition]
My definition.
\end{definizione}\pause
\begin{itemize}
\item A comment about definition;\pause
\item Another comment
\end{itemize}
\end{frame}
\end{document}
我希望每个页面上的定义都有一个计数器，但它会在暂停或新的覆盖后不断改变计数器（使用相同的定理）。
有人可以帮忙吗？

两种方法：
如果你想保留
mdframed，你可以使用\only<2->{\addtocounter{definizione}{-1}}快速破解来获得正确的数字或者直接使用 beamer 自己的定义环境。标题的格式/语言可以调整以匹配您现在的内容，唯一稍微复杂一点的是街区周围的边界。

\usepackage[framemethod=tikz,nobreak]{mdframed}

roundcorner=4pt,linecolor=blue,innerleftmargin=16pt,
innerrightmargin=16pt,backgroundcolor=white, %
frametitlerule=true,frametitlebackgroundcolor=cyan,innertopmargin=\topskip,innerbottommargin=\topskip]{definizione}{Definizione}
