摘要
利用适当改变极距、极位的方法研究台安地电N39°E向自1989年6月中旬以来出现的低值变化。研究结果表明,该变化是由干扰所致,与地震活动无关。
Making use of the method to change polar distance and polar location,a low valueanomaly of Taian earth-resistivity which appears since the middle ten days of June has beenstudied in this paper. The results show that the change was due to interference, and was in-dependent of seismicity.
