【摘要】 根据邢台直接前震N-t图(与M-t图完全一致)和5次MS≥6.0地震活动时序相关性,采用“震情三分律”方法可分别得到大震前82 d,59 d的短期预测和30 h的临震预测;与此同时,若条件许可再采用“对称填补”方法又可作出强震到来前的“活动范围”预测区。指出,此二者都与当代数学理论有某些相似的特性。更多还原

【Abstract】 Based on the time sequence relativity between Fig.N-t(completely the same to Fig.M-t) of direct foreshock of the Xingtai earthquake and five earthquakes of Ms≥6.0,82 days and 59 days of short-term prediction and 30 hours of imminent prediction before large earthquake could be made separately by using the method of "Trisection rule of earthquake".Meanwhile,if possible, the prediction region of "seismicity range" before the strong earthquake occurrence could also be worked out by using the method of "Symmetry padding".It is pointed out that both the two ones have some similar characteristic with modern mathematical theory.更多还原
