According to the theory of formations,some sufficient conditions of saturated formation containing the class of all finite supersolvable groups are got,and some known theorems are generalized.
利用极小子群的弱c-正规性刻画了有限群的结构,得到了有限超可解群的若干充分条件;从群系理论出发,得到了包含超可解群类的饱和群系的充分条件,并推广了一些已知结果。

In this paper,it gets the following results by using the weakly s-permutabilities of subgroups of finite groups: 1) Let F be a saturated formation containing U,H a soluble normal subgroup of G.
利用子群的弱s-置换性得出下列结果:1)设F是包含超可解群系U的饱和群系,H为G的可解正规子群。
