TikZ-cd对某一行的行间距的调整

试试把正文和交换图分开，只把真正交换图的部分用 `tikzcd` 环境画。 ```tex \documentclass[a4paper,UTF8,twoside]{article} \usepackage{tikz-cd} \usepackage{amsmath} \usepackage{amssymb} \usepackage{mathrsfs} \usepackage{extarrows} \usepackage{mathtools} \usepackage[margin=20mm]{geometry} \def\ve{\varepsilon} \newcommand{\mbR}{\mathbb{R}} \newcommand{\mcS}{\mathcal{S}} \newcommand{\normLo}[1]{\|#1\|_{L^1}} \begin{document} $p=1$: \[\begin{tikzcd}[row sep=large] f\arrow[r, mapsto, "H"] \arrow[r, red, bend right=20] & Hf\\ f_n\in\mcS \arrow[u, "L^1"'] \arrow[r, mapsto, "H"] & Hf_n \arrow[u, "\text{\rlap{Conv in Measure}}"'] \end{tikzcd}\] Cauchy Seq in $L^1$: $\left|\left\{x\in\mbR: |(Hf_n-Hf_m)|>\ve\right\}\right| \lesssim \dfrac{1}{\ve}\normLo{f_n-f_m}$,\quad Thm~\ref{thm:ffinmcSHw11} $1<p<\infty$: \[\begin{tikzcd}[row sep=large] f \arrow[r, mapsto, "H"] \arrow[r, red, bend right=20] & Hf\\ f_n\in\mcS \arrow[u, mapsto, "L^p"'] \arrow[r, "H"] & Mf_n \arrow[u, "L^p"'] \end{tikzcd}\] \end{document} ``` 

看不懂你想干啥，建议你把这几句话写在正文里而不是放在tikz环境中，把两个交换图拿出来多分开画
