摘　　要：对比研究了新疆伽师强震群与乌兹别克斯坦加兹里强震群,发现两者不但在分段上极为相似,而且随时间的发展在能量释放的分配形式上也极为相似,且余震都呈共轭分布,主要地震迁移呈多侧扩展型,强震群序列中各次主要地震的发生表现出一定的的继承性特征,强震前中小地震出现平静。从频度及强度上看,两次强震群第一组强震发生后余震频度及强度较低,第二组强震发生后余震频度及强度较高,第三组强震发生后余震频度及强度最高。In the article, the contrast of the strong earthquake swarms between Jiashi in Xinjiang and Jazily in Uzbekistan has been studied. It is shown that the Jiashi strong earthquake swarm is similar to the Jazily＇s, not only in seismogenic period, but also in distributing form of energy release with time. Furthermore, the distribution of their aftershocks is conjugated. The migration of the major earthquake extends to multi-sides. The subdominant event in strong earthquake swarm sequence occurs with successive character to some extent. Mid-small earthquakes appear quiescence before the occurrence of the strong shock. In these strong swarms, the frequency and intensity of the aftershocks are weaker in the first group, stronger in the second group and strongest in the third group.
