| 摘 要： | １９９８年１月１０日张北６．２级地震后，我们根据《地震现场工作大纲和震情分析指南》用ｂ值ｈ值、ｕ值，ｋ值对该次地震序列进行了综合判定。结果认为此次地震为主震余震型。张北地震序列在衰减过程中出现以４级地震为峰值有节律的起伏，在时间上有较规则的准周期，且每一组起伏前密集－平静规律十分明显。

| Abstract: | After the Zhangbei M6. 2 earthquake on January 10, 1998,comprehensive judgement was made for the earthquake sequence by b value,h value,u value and k value. The result considered that the earthquake belongs to main shock aftershock type. The Zhangbei earthquake sequence showed regular fluctuations with earthquake of magnitude 4 as peak value in attenuation process,showed relateively regular quasi-period in time and the concentration-quiet law is quite obvious before each group fluctuation. |
