这里,我抓住了那个符号mathabx
,以免覆盖整个符号集。
如果您取消注释我的 MWE 中的两个fonttable
引用,您将看到我如何确定所需的符号位于插槽中"A4
。
\documentclass[11pt,a4paper]{article}
\usepackage[pdfencoding=auto,psdextra]{hyperref}
%\usepackage{mathabx}
\usepackage{amsmath}
% Setup the mathb font (from mathabx.sty)
\DeclareFontFamily{U}{mathb}{\hyphenchar\font45}
\DeclareFontShape{U}{mathb}{m}{n}{
<5> <6> <7> <8> <9> <10> gen * mathb
<10.95> mathb10 <12> <14.4> <17.28> <20.74> <24.88> mathb12
}{}
\DeclareSymbolFont{mathb}{U}{mathb}{m}{n}
% Define a subset character from that font (from mathabx.dcl)
% to completely replace the \subset character, you can replace
% \varsubset with \subset
\DeclareMathSymbol{\preccurlyeq}{3}{mathb}{"A4}
%\usepackage{fonttable}
\begin{document}
%\fonttable{mathb10}
\begin{equation}
A \preccurlyeq B
\end{equation}
\end{document}
另一种选择是stix
字体
\documentclass[11pt,a4paper]{article}
\usepackage{amsmath,stix}
\begin{document}
\begin{equation}
A \preccurlyeq B
\end{equation}
\end{document}
