作为起点,tikz
(我对此有点熟悉):
\documentclass[border=3.141592mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,
positioning}
\begin{document}
\begin{tikzpicture}[
node distance = 22mm and 11mm,
C/.style = {circle, draw, minimum size=#1},
C/.default = 24mm,
every label/.append style = {inner sep=1pt}
]
\node (a) [C] {};
% elements of the top circle named "a"
\foreach \i in {30, 150, 270}
\draw (a.center) ++ (\i:9mm) -- ++ (\i:6mm);
\node[font=\Large, label= above:A, label=below:1] at (a.90) {$\times$};
\node[C=2mm, label=210:B, label=30:2] at (a.210) {};
\node[C=2mm, label=330:C,label=150:3] at (a.330) {};
%
\node (b) [C, below left=of a] {};
\node (c) [C, below right=of a] {};
%
\draw[very thick, -Straight Barb] ([yshift=-4mm] a.south) -- ++ (0,-7mm);
\end{tikzpicture}
\end{document}
上述 MWE (最小工作示例) 产生:
下面的部分图像代码用于在顶部圆圈上绘制圆圈和十字(它们在您的草图中不太明显),因此您可能需要根据自己的喜好调整它们。类似地,您可以将其添加到其他两个圆圈中。如果您对此感到困惑,请随时寻求帮助。
