摘　　要：本文研究有限群元素共轭类的平均长度问题.利用初等群论方法和有限群特征标理论,在共轭类平均长度为某一定数时,获得了对有限群结构的刻划,且对有限群数量性质的研究是有意义的.This paper studies problem of the average length of conjugacy classes of finite groups. Using the theory of elementary group and character, we get a result to characterize the structure of finite groups when the average length of conjugacy classes of the finite groups is given. This is significant for studying the quantitative property of finite groups.
