| 摘 要： | 本文采用调和分析的方法,处理了全国地下水观测井网中18口井孔的水位和气压资料,求出了水井水位中固体潮体应变各分波群的潮汐系数和位相滞后,对这些结果作了分析和讨论。重点对映震能力较好的滇01井潮汐系数及位相滞后这二个参量与地震的关系,作了较详细的研究。

| Abstract: | In this paper, the ground water level and barometric data of 18 wells which belong to China's underground water monitoring network were proccessed by using the harmonic analysis method. The results obtained from the tidal c oefficient and retardation of phase of each individual solid tide wave swarm of well water 1 evel, were analyzed and discussed. The relation between the tidal coefficient and the retardation of phase of the "Dian 01" well, whose data varied remarkably according to the earthquakes within some distance, was studied emphatically in details. |
