问的是平行且等于吧,记得以前人教论坛讨论过,还有什么字体之类的。不过现在我觉得直接用$\sslash=$就挺好的。

平行且等于简单啊

$AB\stackrel{/\mkern-4mu/}{\raise-.5ex\hbox{=}}CD$

$AB\stackrel{/\mkern-4mu/}{\raise-.5ex\hbox{=}}CD$

\documentclass{article}

\newcommand\px{\mathrel{/\mkern-5mu/}}  %平行
\newcommand\pxeq{\mathrel{\vcenter{     %平行且等于
\ialign{\hfil##\hfil\crcr
$\scriptstyle\px\!$\crcr
\noalign{\nointerlineskip\vskip1pt}$=$\crcr}}}}

\begin{document}

$AB \px CD \pxeq EF$

\end{document}

这是在真 LaTeX 中的,完全不依赖其他宏包的一种定义方式,效果如图。
