| 摘 要： | 利用延庆地震台2004年地电场的观测资料,研究其变化情况,分析引起其变化的具体原因,结果表明:延庆地震台地电场的观测容易受到磁暴、雷雨等干扰,电极的极化影响最为严重,这些因素给地电场震前中短期异常的识别带来了困难,但是从短期来看,地电场观测精度较高,对场地的电磁变化反映比较灵敏。

| Abstract: | In this paper, with the data recorded at Yanqing Seismic Station in 2004, the geoelectric field observation was analyzed for studying its variation along with the reasons. The results indicate that the geoelectric field at Yanqing Seismic Station is interfered by magnetic storm, thunder storm, and seriously interfered by electrode's polarization. These factors bring difficulties to identify the metaphase and short time anomaly of electric field. From the view of short term, however, the geoelectric field observation is of high precision and sensitive to the electromagnetic variation of the field. |
