| 摘要: |
| 若有限群G的每个2-极大子群在G中次正规，则称G为SMSN-群.本文研究了有限群G的每个真子群是SMSN-群但G本身不是SMSN-群的结构，利用局部分析的方法，获得了这类群的完整分类，推广了有限群结构理论的一些成果. |

| Abstract: |
| A flnite group G is called an SMSN-group if its 2-maximal subgroups are subnormal in G. In this paper, the author investigates the structure of flnite groups which are not SMSN-groups but all their proper subgroups are SMSN-groups. Using the idea of local analysis, a complete classiflcation of this kind of groups is given, which generalizes some results of the structure of flnite groups. |
| Key words: power automorphisms nilpotent groups minimal non-nilpotent groups minimal non-SMSN-groups |
