利用锦州义县地震站“十五”观测以来的地电场分钟值观测资料，对辽宁及周边地区Mll4．0级以上地震大地电场的震兆异常特征进行了分析，并对异常机理进行了讨论。研究结果表明：震兆异常特征表现为震前地电场日变形态的畸变、高频脉冲和阶变变化等。
이용금주의현지진참“십오”관측이래적지전장분종치관측자료，대료녕급주변지구Mll4．0급이상지진대지전장적진조이상특정진행료분석，병대이상궤리진행료토론。연구결과표명：진조이상특정표현위진전지전장일변형태적기변、고빈맥충화계변변화등。
Based on the minute value observation of the geoelectric field since "the tenth five-year plan" of Yixian Seismic Station in Jinzhou, the abnormal characteristics of telluric field of ML〉4.0 earthquakes in Liaoning and surrounding areas were analyzed. And the anomaly mechanism was discussed. The results showed that earthquake precursor abnormalities were characterized by the geoelectric field distortion of the daily variation shape before the earthquake, high frequency pulse and order variable changes.
