这里是另一个使用tikz-cd
包的建议:
\documentclass[a4paper,12pt]{article}
\usepackage{amsmath,amssymb}
\usepackage{newtxtext,newtxmath}
\usepackage{tikz-cd}
\tikzset{close/.style={outer sep=-7pt}}
\usepackage{graphicx}
\begin{document}
\begin{tikzcd}[column sep=0cm]
& \text{TOP} \arrow[d, no head]
&\\
& \text{PDIFF} \arrow[ld, no head] \arrow[rd, close, "{\rotatebox{-40}{\scalebox{2.5}{$\sim$}}}", no head] & \\
\text{DIFF} & & \text{PL}
\end{tikzcd}
\end{document}
答案3
我采用这种简单的方法绘制:
\documentclass[tikz]{standalone}
\begin{document}
\begin{tikzpicture}
\path (0,0) node (top) {TOP}
++(-90:1) node (pdiff) {PDIFF}
+(-130:1.5) node (diff) {DIFF}
+(-50:1.5) node (pl) {PL};
\draw (top)--(pdiff)--(diff)
(pdiff)--(pl) node[midway,sloped,above,yscale=.6]{$\sim$};
\end{tikzpicture}
\end{document}
