引言地电在地震前兆测量中是一个重要的手段。对地电测量的干扰可分为两类,一类是非地震因素引起的地电阻率的变化,一类是地电测量过程中一些不需要的信号引起的干扰。本文只是论述后一类干扰即地电测量过程中的干扰。地电测量中存在的各种干扰影响着地电测量的精度。在这些干扰中,有的是和一般电气测量中存在的干扰相同;有的则是在地电测
Introduction Geoelectricity is an important tool in earthquake precursor measurements. There are two types of interferences to geoelectric measurements, one is the change of geo-resistivity caused by non-seismic factors, and the other is the interference caused by some unwanted signals during the geoelectric survey. This article only discusses the latter type of interference that is the interference in the geoelectric measurement process. Geoelectric measurements in the presence of a variety of interference affect the accuracy of geoelectric measurements. Among these disturbances, some are the same ones that exist in general electrical measurements; some are in geoelectric measurements
