【摘要】 本文通过对山西临汾中心地震台大地电场资料分析,给出了农田灌溉、雷电、高压直流输电、铁丝网接地等几种常见自然因素引起的典型干扰曲线形态,以及河津、洪洞2次地震前的异常电信号图像特征,为今后观测数据处理、日常会商及异常跟踪分析等工作提供参考。更多还原

【Abstract】 Based on the analysis of the geoelectric field data of the Linfen Seismic Station in Shanxi Province,this paper presents the typical interference curve patterns caused by several common natural factors such as farmland irrigation,lightning,HVDC transmission and barbed wire grounding,as well as the characteristics of abnormal electrical signals before the Hejin and Hongtong earthquake.These results have positive reference significance for workers engaged in observation data processing,daily meeting and abnormal tracking analysis.更多还原
