| 摘 要： | 本文给出了一种处理井水位的新方法，它考虑了井水位对气压和固体潮响应的滞后影响。利用泰勒和杜得森展开法，导出了计算井水位气压系数，固体潮系数以及它们的滞后时间的公式，并给出了考虑滞后影响的井水位气压与固体潮改正公式。我们利用这一新方法处理了豫０１井１９８３年的观测资料，计算出每天的井水位固体潮，气压系数和它的滞后时间。该４种参数在１９８３年１１月７日菏泽Ｍｓ５．９级地震时大幅度变化。而且在地震前，后

| Abstract: | A new method for processing well water level has been proposed in this paper.With the lag influence of response of water level to barometric pressure and earth tide taken into consideration,using Doodsoon's tidal expansion and Taylor's expansion of progression,the calculation formulas of the tidal and barometric coefficients of water lvevel and their lag time have been deduced and the corrected formulas of water level,pressure and earth tide with consideration of lag influence has also been presented.The daily coefficients of water level,earth tide and pressure and their lag time have been calculated using the new method to process the data observed in 1983 at well No. Henan 01.The above 4 coefficients show great changes before,during and after Heze M=5.9 earthquake on Nov.7,1983. Water level and pressure coefficient on Sept.9 and Nov.2 changed decreasingly and increased greatly on Nov.20 after the earthquake.Lag time of response of water level to pressure obviously reduced on Sept.23,the tidal coefficients of water level increased in a big amplitude on Nov.2 and decreased on Nov. 7-8.This method has provided a new way for analysing precursors. |
