答案1
wasysym
包装的\ocircle
宽度对我来说似乎正确:
\documentclass{book}
\usepackage{amsmath, amssymb}
\usepackage{wasysym}
\begin{document}
$\times$
$\otimes$
$\ocircle$
\end{document}
编辑:
如果您只是想使用这些符号作为表中的一种复选标记,则可以使用\scalebox
加载graphicx
包。
为了方便起见,我在这里创建了三个宏(\mytimes
,\myotimes
和\myocircle
):
\documentclass{book}
\usepackage{amsmath, amssymb}
\usepackage{wasysym}
\usepackage{graphicx}
\usepackage{array}
\usepackage{booktabs}
\newcommand{\mytimes}{\scalebox{4}{$\times$}}
\newcommand{\myotimes}{\scalebox{4}{$\otimes$}}
\newcommand{\myocircle}{\scalebox{4}{$\ocircle$}}
\begin{document}
\begin{tabular}{l>{\centering\arraybackslash}m{4em}}
\toprule
\multicolumn{2}{c}{Legend of symbols}\\
\midrule
Expected result & \myocircle \\
Calculated result & \mytimes \\
Expected result equal to calculated one & \myotimes \\
\bottomrule
\end{tabular}
\end{document}
