摘要: 处理、分析了江苏省4个台的地电场日变化资料,结合地磁场水平分量H、线应变理论固体潮,研究了地电场日变化特征和差异,得到:(1)4个台地电场日变化明显,主要以12小时的半日波成分最强,8小时周期和全日波成分次之;(2)地电场日变化存在地磁场和固体潮影响。靠近海边及湖泊的台站,受固体潮的影响较为明显,各方向还具有明显的固体潮半月波,但没有像固体潮一样大小的波;而远离江、海、湖的一些台站观测到的地电场日变与地磁水平分量比较相关,其差异性与台站的位置、电性结构有关系。

Abstract: Based on diurnal electric field data of four stations of Jiangsu Province,combined with horizontal component of geomagnetic field and line tidal strain theory,this paper studies the characteristic of the diurnal variation and differences of the electric field.The result shows that:(1) the amplitude of semi daily wave is the biggest followed by the 1/4 daily wave;(2) Diurnal variation of electric field is affected by magnetic field and tidal.The electric field of the stations near the sea and lake are obviously affected by earth tide while the electric field of the stations away from the river,sea and lake are more related to the horizontal component of the geomagnetic daily variation,the differences between them are affected by the location of stations and the electrical structures.
