你可以和锚一起玩:
\documentclass{beamer}
\usepackage{amsmath}
\usepackage{tikz-cd}
\begin{document}
\begin{frame}[fragile, t]{My slides}
\begin{equation*}
\begin{tikzcd}
\text{The starting point}
\arrow[end anchor=north west]{d} \\
|[anchor=real west]|\text{first node}
\end{tikzcd}
\end{equation*}
\end{frame}
\end{document}
或者,你也可以使用一些廉价的技巧。
\documentclass{beamer}
\usepackage{amsmath}
\usepackage{tikz-cd}
\begin{document}
\begin{frame}[fragile, t]{My slides}
\begin{equation*}
\begin{tikzcd}
\text{The starting point}
\arrow{d} \\
\phantom{\text{first nod}}\text{first node}
\end{tikzcd}
\end{equation*}
\end{frame}
\end{document}
或者
\documentclass{beamer}
\usepackage{amsmath}
\usepackage{tikz-cd}
\begin{document}
\begin{frame}[fragile, t]{My slides}
\begin{equation*}
\begin{tikzcd}
\text{The starting point}
\arrow{d} \\
|[text width={1.88*width("first node")},align=right]|\text{first node}
\end{tikzcd}
\end{equation*}
\end{frame}
\end{document}
