摘　　要：利用后土桥等地震台的大地电场分钟值资料,分析了各方向的日变形态和特征。结果发现,一般各方向日变与地磁场日变近似,出现双峰单谷。而后土桥地震台有别于其他地震台,东西向以半日波为主,出现双峰双谷。Shapes and characteristics of daily variation of each direction of geoelectric field at the seismological stations such as Houtuqiao etc are analyzed using their minute value data. The result indicates that daily variation of each direction of geoelectric field usually appears double peaks and single trough, just close to that of geomagnetic field, while the case at Houtuqiao Seismological Station is distinct from other seismological stations, being mainly half-day wave with double peaks and double troughs in its EW direction.
