处理、分析近年来山西夏县地震台大地电场观测数据发现,该台地电场正常日变化形态呈现＂双峰双谷＂特征;存在＂单谷单峰＂的年变化特征;对地磁暴反应明显;对山西地震带距台站300 km范围内发生的较强地震,震前存在较为明显的异常信息。该研究为正确分析、运用夏县台大地电场观测数据提供基础。

Through analysis on observation data of Earth＇s electric field of Xiaxian, Shanxi Seismological Station, it is found that normal daily variation of Earth＇s electric field of the station appears characteristic of double apexes and double valleys , whereas that yearly variation characteristic is single apex and single valley. The response to geomagnetic storm is distinct and rather obvious anomaly appears before the relatively larger earthquakes that occur within 300 km around the station at Shanxi earthquake belt. The study offers basis for analyzing and using the observation data of Earth＇s electric field of Xiaxian Seismological Station.
