摘要
2001年8～9月间,江油地电台N10°E测向视电阻率ρs值出现持续下降,变化形态打破年变,降幅约3%,很像是一次孕震异常。但经现场核实为供电电源极性接反漏电所致,与理论计算出的漏电影响系数相反。
From August to September in 2001,the apparent resistivity in the Jiangyou seismic station fell down,The change range is up to 3% of a year changes.The abnormal changes result from the wrong connecting of the electric polar of the geo-electric meter.In this paper,the process of finding the cause is introduced.
