摘要 为了得出一个超可解群的充分条件,利用有限群的π-拟正规子群和半覆盖远离子群的概念。群G的子群H称为G的π-拟正规子群,如果它与G的每一个Sylow子群可交换,群G的子群H称为G的半覆盖远离子群,如果H覆盖或者远离G的某个正规列的每一个正规因子。并将所得的结果推广到一些已知的结论。 In order to obtain a sufcient condition of supersolvable groups, by using two concepts of π-quasinormal sub- groups and semi cover-avoiding subgroups of finite groups . A subgroup H of a group G is called a π-quasinormal sub- group of G, if it permutes with every Sylow subgroup ofG. A subgroup H of a group G is called a semi cover-avoiding subgroup, if H either covers or avoids every normal factor of a normal series of G. The results extend some known conclusions.
