本文给出一种简捷的数据处理方法,可以比较满意地消除地电观测资料中的“年变”干扰。对其它方法观测资料中的周期性干扰,用该方法略加改动也可达到同样的滤波效果。文中对若干台站的地电资料给出处理前和数种方法处理后的对比,显示出本文给出的方法所具有的良好效果。 This paper presents a simple method of data processing, which can satisfactorily eliminate the “annual change” interference in the geoelectric data. For other methods of periodic interference in the observed data, a slight modification with this method can achieve the same filtering effect. In this paper, the comparison of the geoelectric data of several stations before and after processing by several methods shows the good effect of the method given in this paper.
