摘　　要：h参数只局限于预测地震序列预后强度,本文试图把它的物理含义开拓到通常的中强地震预测工作中,提出地震活动时间频度参数h1的研究。本文讨论了h1参数的物理意义和研究途径。其次,讨论了参数的异常特征,表明中强地震大都发生在h1低值后的升高阶段并有空间特征显示。最后给出了误差和讨论。Parameter h is confined to estimating the prognosis intensity of earthquake sequences. This article attempts to extend its physical meaning to the usual strong earthquake prediction, proposing the research on seismic activity time-frequency parameters h1. This article discusses the physical meaning and researching approaches of parameter h1. Secondly, discussing the abnormal characteristics of h1 parameter, indicating strong earthquakes occur mostly in the elevated stage after the low value h, and spatial characteristic is showed. Finally, the error and discussion are given.

关 键 词：h1参数 研究途径 时空分布特征 误差和讨论
