聊古－1井氮氦比观测值的区间概率与地震的关系

本文介绍了计算聊古－１并氮氦比观测值区间概率的两种方法。采用了非线性的褶积滤波结合多元回归的方法排除氮氟比观测值中的干扰因素。并分析了它与１９８１年宁晋Ｍｓ５．８级地震和１９８３年菏泽Ｍｓ５．９级地震之间的关系。在这两震前２个月，其两种区间概率都明显地出现异常，而且都在曲线的极值处发震，震后又恢复到正常值。

THE RELATIONSHIP BETWEEN INTERVAL PROBABILITY OF THE RATIO OF NITROGEN TO HELIUM IN WELL LIAOGU-1 AND EARTHQUAKE

In this poper, the two calculstion methods using interval probsbility of the ratio of nitrogen to helium in well Liaogu-1 were introduced. Nonlinear faltung filtering and multiple regression wereadopted to remove the interference factors which influence the othervation of N/Ne in nonlinear relation with delayed memory effect. The relstionship between interval Ptobobility of N/Ne and the 1981Ningjin earthquake Ms 5. 8 and the 1983 Heze earthquake Ms 5. 9 were analysed. The results showthat the marked anomalous values of two intervals Probability of N/Ne appeared two months beforethe two earthquakes and the earthquakes occurred at the extreme value of curve and returned to normalvalue after the earthquakes.
