摘要
在介绍榆树地震台地电台站概况的基础上,利用比对观测数据,对地电观测中遇到的场地干扰、降雨干扰、雷电干扰等进行分析,结果表明:在相同条件下,同台比对观测更有利于地电观测中干扰的判定、识别。
On the basis of introduction at Yushu Seismic Station of geo-electrical resistivity and selfpotential,the interference factors during geoelectric observation,for example,site disturbance,rainfall interference,interferences of thunderbolt,and so on,are analyzed by comparing the observed data.The results show that under the same conditions,the same comparison observation is more conducive to determine the interference in recognition of geoelectric observation.
