公式用列表和`\phantom`对齐下就可以一行行显示了，插图可以考虑用`tikz`的绝对坐标来插图，还可以配合`tikzmark`做标注 ```tex \documentclass{beamer} \usepackage{amsmath} \usepackage{enumitem} \usefonttheme[onlymath]{serif} \usepackage{calc} \usepackage{tikz} \usetikzlibrary{tikzmark} \setlist[itemize]{ labelsep=1em/6, } \newcommand{\myitem}[1]{ \item<#1->[\phantom{$f(x)$}] } \begin{document} \begin{frame}{test} \begin{itemize} \item<1->[$f(x)$] $= a + b + c$ \myitem{2} $= c + d + e\tikzmark{a}$ \begin{tikzpicture}[remember picture, overlay] \node[minimum height=2cm, minimum width=2cm, fill=teal, anchor=east, draw] (b) at (current page.east) {Fig}; \draw[->, red] (pic cs:a) ++(0, .2em) to[bend left] (b.west); \end{tikzpicture} \myitem{3} $= x + d + e$ \myitem{4} $= y + d + e$ \end{itemize} \end{frame} \end{document} ```
