【摘要】 利用经验类比的方法，对1999年11月29日岫岩偏岭5．6级地震前震群序列及以往在辽宁地区发生的典型具有预报意义的1988年2月25日彰武4．8级地震前岫岩偏岭前兆震群和1975年2月4日海城7.3级地震前震序列进行了详细研究．结果显示，1999年11月29日岫岩偏岭5．6级地震前震群序列与1975年2月4日海城7．3级地震前震序列的统计特征及性质相同，因此，认为该序列属于前震序列．同时，还提出了将序列的表象特征与其参数特征相结合的识别序列性质的方法．更多还原

【Abstract】 By using of the method of experience analogy,we have deeply studied some earthquake swarm sequences with typical forecasting signifience occurred in Liaoning province .The result shows that the quality and statistical characters of earthquake swarm sequence prior to the Ms5.6 earthquake occurred in Pianling, Xiuyan county in 1999 is similar to that of the foreshock sequences prior to the Ms 7.3 earthquake occurred in Haicheng in 1975. They both belong to the foreshock sequence. Meanwhile, the result has also proposed a method to judge the sequence quality to combine external characters of sequence with parameters characters of sequence.更多还原
