摘　　要：文中重点讨论了大华北地区,A、B、C三类地震活动的地电震后效应特征。研究表明,不同地震活动类型的地电震后效应差异是比较明显的。这种差异性可为未来震情判断提供地电前兆依据。This paper introduced the features of geoelectrical post-seismic effects of the A-, B- and C-type seismic sequences in the large North China region; the effects are different for different main seismic sequences, which provide the geoelectrical precursory basis for judging the intensity and location of new earthquakes as well as this is also a new attempt to use the geoelectrical method into the prediction in the aftershock prediction after the mainshocks.

关 键 词：地电阻率 震后效应 识别法 地震异常
