四极对称的视电阻率测量中,外线漏电是地震前兆研究中一个重大干扰因素。为了研究线路漏电对视电阻率测量影响的定量关系。找到一种简单易行的消除或压低漏电干扰的方法,我们于1984年5月在安徽省屯溪地电台做了漏电影响的有关实验。 屯溪台基岩岩性为砂岩。实验选用EW向线路,AB=1000m,MN=200m,四极对称,A极供正电(图1),电极埋深2m。极板为100cm×100cm×0.3cm的铅板。外 In quadrupole symmetry apparent resistivity measurement, outside leakage is a major disturbing factor in the study of earthquake precursors. In order to study the quantitative relationship between line leakage and apparent resistivity measurement. Find a simple way to eliminate or reduce leakage interference method, we conducted in May 1984 in Tunxi, Anhui Province radio leakage related experiments. Tunxi bedrock lithology sandstone. The experiment uses EW line, AB = 1000m, MN = 200m, quadrupole symmetry, A pole for the positive (Figure 1), the electrode depth 2m. The plates are 100 cm × 100 cm × 0.3 cm lead plates. outer
