h值在新疆伽师强震群趋势判断中的意义

仅就h值在新疆伽师强震群趋势判断中的作用进行了分析讨论。在传统的h值判定原则的基础上，利用序列活动自相似的客观存在，提出了自强震发生后从其后较大中强地震起算的h值判别准则。两种算法的结合在伽师强震群预报过程得到了较好的验证。同时对预报过程中出现的问题，如h值的算法问题、强震及强震群中震级的估算问题进行了分析讨论。

APPLICATION OF h-VALUE FOR STRONG EARTHQUAKE SWARMS TREND DIAGNOSES IN JIASHI OF XINJIANG

The authors have analysed h-value for Jiashi strong earthquake swarms trend diagnoses in Xinjiang. On the basis of h-value decision criteria,they have put forward hvalue discriminant criteria from the larger medium-strong aftershock after strong earthquake by using sequence active self-similarity. The combination of the two algorithms isbetter verified in Jlashi strong earthquake swarms. They have discussed some problems inthe prediction process,such as h-value and estimation of magnitude.
