如果先把互不共轭的同阶元的共轭类长合并得到同阶类长，再把同阶类长相加就得到了阶方程。

We can get the size of same order elements if we put some different conjugacy classes with the same order elements together, then we will get order equation of a finite group.

文中，我们给出了有限极小非abel群的一个共轭类长——刻画并建立某些相关的结果。

In this paper, we give a conjugacy-class-length characterization of finite minimal non-abelian groups and establish some related results.
