摘要
本文利用一阶差分方法计算了济阳坳陷四井孔气压一水位的相关系数、气压效率,统计表明,利用气压效率、相关系数的变化范围来判定地下水位的超常变化作地震的短、临预报是可行的。
By the first order difference method,in this paper the author has calculated the correlation coefficient and the atmospheric pressure efficiency between the atmospheric pressure and groundwater table of four wells in Jiyang basin. The statistical results indicate that the changing scale of correlative coefficient and atmospheric efficiency can be used to determine the abnormal change of groundwater table, by which it is possible to present short—term and impending earthquake predictions.
