摘　　要：本文分析和总结了在7.4级渤海地震前长清地震台电感异常的三个基本特征:(1)临震前曲线产生大幅度的跳跃形成锯齿状;(2)曲线变化斜率在震前3个月发生明显改变;(3)震后曲线逐渐恢复正常形态。In this paper,the characteristics of the inductance anomaly at Changqing station before theBohai Sea earthquake (7.4Ms) are analysed and summarized:(1).there is an abrupt rise beforethe earthquake to form a sawtooth-like curve;(2).the slope of the curve changes apparentlythree monthes before the earthquake;(3).the curve recovers to its normal form gradually afterthe earthquake.
