摘　　要：通过对邢台及邻区永年台应力的计算和对余震、余震频度关系的分析,表明邢台强烈地震发生后,震中区应力稍小于外区应力;应力的变化和余震频度、强余震关系较明显.In this paper,based on the calculation of stress in Xingtai area and near Yongnian station,and analysing of aftershock freqency relation, it is discovered that after the Xingtai earthquake, the stress in epicenter area is less than periphery, and the relationship between the stress and the aftershock frequency and strong after shock is significant.

关 键 词：邢台 应力 余震频度 地震
