答案1
解决方案 1:
这可能就是你要找的:
\documentclass{article}
\let\mysub=\subset
\usepackage{mathabx}
\begin{document}
The original: $\mysub$
mathabx: $\subset$
\end{document}
解决方案 2:
\subset
我搜索了包中的定义mathabx
,另一个不使用此包的解决方案是:
\documentclass{article}
\DeclareFontFamily{U}{matha}{\hyphenchar\font45}
\DeclareFontShape{U}{matha}{m}{n}{
<5> <6> <7> <8> <9> <10> gen * matha
<10.95> matha10 <12> <14.4> <17.28> <20.74> <24.88> matha12
}{}
\DeclareSymbolFont{matha}{U}{matha}{m}{n}
\DeclareFontSubstitution{U}{matha}{m}{n}
\DeclareMathSymbol{\mysubset}{3}{matha}{"80}
\begin{document}
The original: $\subset$
Own symbol: $\mysubset$
\end{document}
答案2
您可以使用 设计自己的细子集符号\scalebox
。.8
根据需要调整缩放因子。
\documentclass{article}
\usepackage{graphicx}
\newcommand{\thinsubset}{\mathrel{\scalebox{1}[.8]{$\subset$}}}
\newcommand{\thinsubseteq}{\mathrel{\scalebox{1}[.8]{$\subseteq$}}}
\begin{document}
$A\subset B\subseteq C$
$A\thinsubset B\thinsubseteq C$
\end{document}
更复杂的版本,使用\mathpalette
将允许符号用作下标:
\documentclass{文章}
\usepackage{graphicx}
\usepackage{amsmath}
\makeatletter
\newcommand{\thinsub}{\mathrel{\mathpalette\thin@sub\relax}}
\newcommand{\thin@sub}[2]{\m@th#1\text{\scalebox{1}[.8]{$\subset$}}}
\newcommand{\thinsubeq}{\mathrel{\mathpalette\thin@subeq\relax}}
\newcommand{\thin@subeq}[2]{\m@th#1\text{\scalebox{1}[.8]{$\subseteq$}}}
\makeatother
\newcommand{\thinsubset}{\mathrel{\scalebox{1}[.8]{$\subset$}}}
\newcommand{\thinsubseteq}{\mathrel{\scalebox{1}[.8]{$\subseteq$}}}
\begin{document}
$A\subset B\subseteq C_{A\subset B\subseteq C}$
$A\thinsub B\thinsubeq C_{A\thinsub B\thinsubeq C}$
\end{document}
