摘要
A comparative analysis of the spectrum of quiet-day geoelectric field and the H component of geomagnetic field at Xinyi Seismic Station, and the volume strain data at Lianyungang Seismic Station showed that the geoelectric field in which Xinyi Station lies is the result from the geomagnetic field and earth tide.The variation of NS component of geoelectric field lags a little behind the variation of H component of magnetic field. Meanwhile, it included the effect of solid tide. Moreover, the geoelectric field in which the Xinyi Station lies varied with the season. Finally, the mechanism of the variation of geoelectric field in which Xinyi Station lies was discussed.
