答案1
简单代码:
\documentclass[tikz]{standalone}
\usetikzlibrary{calc}
\begin{document}
\begin{tikzpicture}[outer sep=.2cm,inner sep=0pt,line width=.7pt,line join=round]
\draw (-60:3)arc(-60:60:3) (-60:5)arc(-60:60:5);
\draw [rotate=180](-60:3)arc(-60:60:3) (-60:5)arc(-60:60:5);
\draw (60:3)--(60:5)node[above]{c}--coordinate[label=above:b](b)(120:5)node[above]{a}--(120:3)--coordinate(b')(60:3)
(240:3)coordinate(m')--(240:5)coordinate[label=below:m](m)--(-60:5)coordinate[label=below:h](h)--(-60:3)coordinate(h')--(240:3);
\draw(b)--(b');
\foreach \pos/\lett in {0/i,1/j,2/k,3/l}
\draw ($(h')!\pos/3!(m')$)--(h-|{$(h')!\pos/3!(m')$}) node[below]{\lett};
\foreach \ang/\lett/\lettt in {-36/g/q,-12/f/p,12/e/o,36/d/n}{%
\draw (\ang:3)--(\ang:5) node at (\ang:5.2) {\lett};
\draw[rotate=180] (\ang:3)--(\ang:5) node at (\ang:5.2) {\lettt};}
\end{tikzpicture}
\end{document}
