摘要
Abstract
The spectrum of quiet-day geoelectric field and the geomagnetic field H component in Xinyi Seismic Sation are comparatively analyzed. The result showed that- the changes of geoelectric field and the magnetic field in Xinyi Seismic Station are closely related. The changes of the NS component of the geolectric field and the H component of magnetic are pseudo synchronous; while the changes of EW component of geoelectric field and the H component of magnetic field are similar, but with reverse shape. Using FFT spectrum analysis, it is shown that there are different correlation between NS and EW component of geoelectric field with the geomagnetic field in dominant period. This result explained one important mechanism of geoelectric field in the Xinyi Seismic Station.关键词
