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}
