摘要
Abstract
Geoelectric field observation is one of the earthquake electromagnetic precur-sory observation methods.Due to the reasons for the observed variables,interference factors are more.In this paper,five kinds of interference and its typical changes,such as the inter-ference encountered in the same field observation,lightning interference,rainfall,electrode polarization interference,storm disturbance are analyzed and recognized in Jiashan seismic geoelectric field observation.The interference are effectively eliminated so as to extract the information of earthquake precursors.The methods and analysis in this paper provide a relia-ble basis for the analysis and usage of the electric field data in the possible earthquake predic-tion,and also provides the reference for the stations with similar observation.关键词
