| 摘 要： | 在1989年大同6.1级、1990年大海坨山5.0级及1998年张北6.2级等地震前，平谷地震台的地电阻率都出现了不同程度的异常。中对每个地震地电阻率异常做了分析，并根据台站的地质构造情况作进一步探讨。

| Abstract: | Before Datong earthquake with magnitude 6.1 in 1989, Dahaituo Mountain earthquake with magnitude 5.0 in 1990 and Zhangbei earthquake with magnitude 6.2 in 1998, earth resistivity anomaly appeared at Pinggu Seismic Station to different degrees. This paper introduced the change of earth resistivity anomaly for every earthquake and conducted further analysis based on the geological tectonics around the seismic station. |
