| 摘 要： | 处理、分析榆树地震台自建台以来2 604天的地电场分钟值数据,结果表明;①该台地电场正常的日变化曲线形态呈现典型的"双峰单谷"变化;②地电场分钟值曲线峰谷极值时间与本地日出和日落时间吻合;③地电场观测记录的短周期信号(小于1 h)受观测环境的影响较小;④在中强地震前,能够捕捉到明显的异常信息,等等。

| Abstract: | In this paper, the minute value data of geoelectrie field at Yushu Seismic Station in 2 604 days since the station has constructed are processed and analyzed, the results shows that ：① The typical daily change of the geoelectric field observed at Yushu Seismic Station is double peaks and single valley;②The time of peaks and valley extremum for curve of minute value of geoelectric field coincide with sunrise and sundown in local area③The influence is smaller in short period signal（less than one hour）by observation environment of geoelectric field ;④The evident abnormal information were caught before middling and strength earthquakes, and so on. |
