摘要
20 0 0年 2月至 5月 ,榆树台地电阻率出现异常 ,且该异常具有一定的特征。按《规范》要求 ,对外线路、观测仪器、观测环境等进行检查 ,结果发现异常是由于供电电极老化 ,接地电阻远大于《规范》要求的 3 0Ω所引起。
The anomaly of geoelectricity at the Yushu seismic station from Feburary to May in 2000.By checking on the observation instrument,observation environment and external line equipment and so on.It is found that the anomaly was caused by electrode and high ground connection resistivity greatly more than 30Ω which required by the rule.
