河北昌黎台地电场数据与固体潮的初步研究
Preliminary Study of Geoelectric Field Data and Earth Tide at Changli Station

对2014—2016年昌黎台地电场资料进行分析，结果发现昌黎台北南测向地电场数据曲线表现为双峰单谷；东西测向地电场数据曲线表现为双峰双谷，半日波比较明显，受固体潮影响较大，属于TGF-A型潮汐地电场。
The 2014-2016 geoelectric field observation data from the Changli station, Hebei province, are analyzed in this study. Results indicate that the daily variation in NS components of the geoelectric field exhibits double peaks and a single valley, similar to that of geomagnetic fields. In contrast, the daily variation in EW components of the geoelectric field has double peaks and double valleys with obvious, semi-diurnal waves, which are affected by the earth tide. The geoelectric field at Changli station is a tidal geoelectric field.
