设计 medcirc 和 circledtimes 符号

Question

这会很棒

1. 仅使用\medcirc和\circledtimes来自pxfonts或
2. 用其他技术设计类似的符号。

来自的符号pxfonts非常好，但是当我连接包时，文本中的所有符号都被来自的符号替换pxfonts。

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{pxfonts}

\begin{document}

1. Only medcirc and cirledtimes symbols are required from pxfonts: \par
 $\cdot^{\medcirc}$ and $\cdot^{\circledtimes}$.\par
2. The problem is that all symbols are substituted by pxfonts package,
 for example, just look at the text and formula $g(f)=a$.

\end{document}

也有类似的问题pxfonts，但似乎没有解决。也许用其他方式设计符号更好。

仅在列表中使用 pxfonts

本地使用包

Answer 1

如果您只想使用这两个符号而不pxfonts加载它，请在序言中添加以下几行：

\DeclareSymbolFont{symbolsC}{U}{pxsyc}{m}{n}
\SetSymbolFont{symbolsC}{bold}{U}{pxsyc}{bx}{n}
\DeclareFontSubstitution{U}{pxsyc}{m}{n}
\DeclareMathSymbol{\medcirc}{\mathbin}{symbolsC}{7}
\DeclareSymbolFont{symbolsZ}{OMS}{pxsy}{m}{n}
\SetSymbolFont{symbolsZ}{bold}{OMS}{pxsy}{bx}{n}
\DeclareFontSubstitution{OMS}{pxsy}{m}{n}
\DeclareMathSymbol{\circledtimes}{\mathbin}{symbolsZ}{10}

梅威瑟：

\documentclass{article}
\usepackage[T1]{fontenc}
%\usepackage{pxfonts}

\DeclareSymbolFont{symbolsC}{U}{pxsyc}{m}{n}
\SetSymbolFont{symbolsC}{bold}{U}{pxsyc}{bx}{n}
\DeclareFontSubstitution{U}{pxsyc}{m}{n}
\DeclareMathSymbol{\medcirc}{\mathbin}{symbolsC}{7}
\DeclareSymbolFont{symbolsZ}{OMS}{pxsy}{m}{n}
\SetSymbolFont{symbolsZ}{bold}{OMS}{pxsy}{bx}{n}
\DeclareFontSubstitution{OMS}{pxsy}{m}{n}
\DeclareMathSymbol{\circledtimes}{\mathbin}{symbolsZ}{10}

\begin{document}

1. Only medcirc and cirledtimes symbols are required from pxfonts: \par
 $\cdot^{\medcirc}$ and $\cdot^{\circledtimes}$.\par
2. The problem is that all symbols are substituted by pxfonts package,
 for example, just look at the text and formula $g(f)=a$.

\end{document}

Answer 2

既然您特别提到使用其他技术设计符号，那么这里有一个替代方案。我导入了 Karl 接受的解决方案，只是为了展示两者的比较。

在目前的解决方案中，我使用堆栈来覆盖字形，并使用scalerel包来允许事物扩展到不同的数学样式。

\documentclass{article}
%\usepackage{pxfonts}
%Karls import font solution, for comparison
\DeclareSymbolFont{symbolsC}{U}{pxsyc}{m}{n}
\SetSymbolFont{symbolsC}{bold}{U}{pxsyc}{bx}{n}
\DeclareFontSubstitution{U}{pxsyc}{m}{n}
\DeclareMathSymbol{\medcirc}{\mathbin}{symbolsC}{7}
\DeclareSymbolFont{symbolsZ}{OMS}{pxsy}{m}{n}
\SetSymbolFont{symbolsZ}{bold}{OMS}{pxsy}{bx}{n}
\DeclareFontSubstitution{OMS}{pxsy}{m}{n}
\DeclareMathSymbol{\circledtimes}{\mathbin}{symbolsZ}{10}
%Current solution
\usepackage{graphicx}
\usepackage{stackengine}
\usepackage{scalerel}
\def\mcirc{\scalebox{.7}{$\bigcirc$}}
\def\nmediumcircle{\kern-.1pt\mcirc\kern-6.9pt\mcirc}
\def\ntimesincircle{\mathbin{%
  \stackengine{-.74pt}{\nmediumcircle}{\scalebox{.96}{$\times$}}{O}{c}{F}{T}{L}}}
\def\mediumcircle{\mathbin{%
  \ThisStyle{\scalebox{.87}{$\SavedStyle\scalerel*{\nmediumcircle}{b}$}}}}
\def\timesincircle{\mathbin{%
  \ThisStyle{\scalebox{.87}{$\SavedStyle\scalerel*{\ntimesincircle}{b}$}}}}
