有没有办法强制思维导图中的所有节点具有相同的大小，而不管它们在树中的层次结构如何？

你可以修改每个概念的风格：
\tikzset{every concept/.style={minimum size=2cm, text width=2cm}}
计算机科学思维导图示例与手册中的几个级别一样，通过这种更改，如果文本没有放大，则所有概念节点的大小都相同：

\usepackage{tikz}
\usetikzlibrary{mindmap,trees}
% Here we change the style for all concepts: (Stefan K.)
\tikzset{every concept/.style={minimum size=2cm, text width=2cm}}
