摘要
本文研究了我国首次进行的电磁多参数综合观测资料。主要结果:1.电磁多参数资料丰富,可利用的信息量大;2.测区周围290km范围内的5.0级以上地震前都出现电磁前兆异常;3.地震前地壳中出现电磁前兆的时间要比空中出现的早6——14倍之多。
In this paper,the comprehensive observation data of electromagnetic multiparameters first made by our coutry are studied,the main results show that: (1)the electromagnetic multiparameters data are rich,and its valuable quantity of informations are plentiful; (2)The range of electromagnetic precursor anomaly before M_s≥5.0 earthquakes is 290km around the observation area; (3)The time Of electromagnetic precursor from the crust is earlier 6---14 times than that from the sky.
