金寨台低频电磁扰动观测的降雨影响与校正

本文描述了金寨地震台DPDC-2低频电磁扰动仪和GS-2000电磁扰动仪的观测原理及其运行环境,利用金寨地震台最近两年的数字观测资料,分析该台电磁波变化与降雨的关系,认为两者之间存在着一定的相关关系,降雨是造成电磁波突变的主要原因,并尝试通过数学方法剔除资料中的降雨影响。

This paper describes the observational principle and operating environment of DPDC-2 low frequency electromagnetic disturbance instrument and GS-2000 electromagnetic disturbance instrument of Jinzhai Seismic Station. Based on the digital observation data of Jinzhai Seismostation in recent two years, this paper analyzes the changes of electromagnetic wave and rainfall Relations, that there is a certain correlation between the two, rainfall is the main cause of electromagnetic wave mutation, and try to exclude the mathematical effects of rainfall in the data.
