以中国大陆一百个地电场台站的数据为分析基础,将潮汐地电场分类为近正弦形的TGF-A型和近梯形的TGF-B型.TGF-A型地电场与固体潮汐密切关联,基本分布在大面积水域附近,并与附近水域面积和距离、岩性结构、构造活动等因素有关.TGF-B型地电场与气潮作用产生的空间S_q电流关系密切,并与岩石饱和度、渗透率等有关.TGF-A型波形畸变揭示了岩石所受应力可能出现变异,导致岩石裂隙水周期性渗流突变;TGF-B型背景值跃变可能是岩石微破裂加剧导致地下水向破裂区渗流.两类潮汐地电场变异的机理可能是地电场数据应用于强震短临分析的理论基础.

Based on the analysis of data from 100 geoelectrical field observatories in China continent, the tidal geoelectrical field can be divided into the TGF-A of approximate sine waves and the TGF-B of approximate trapezoidal waves. TGF-A was produced basically by large water area nearby, it is not only closely related to solid tide, but also closely related to the acreage and distance of the nearby water area, lithology structures and geotectonic movement, and so on. TGF-B is closely related to the S_q current produced by air tide, and also to the degree of saturation and permeability of the rock, and so on. The reason for TGF-A waveform distortion may be alteration of cranny water periodic transfusion in the rock due to stress change, and the abrupt change of TGF-B background value may be caused by ground fluid transfusion into rock area with increased cracks. These two mechanisms could be the theoretical foundation for application of tidal geoelectrical field data in short-term and impeding strong earthquake prediction.
