聊古-1井氮氦比区间概率信息量与地震的关系
|
摘要
采用了非线性的褶积滤波结合多元回归的方法排除聊古１井氮氦比观测值中的干扰影响，然后计算了其观测值区间概率的信息量．分析了信息量与１９８１年宁晋ＭＳ５．８地震和１９８３年菏泽ＭＳ５．９地震的关系．结果显示，在这两次地震前２个月左右，氮氦比信息量都明显地出现升高异常，地震后恢复到正常值
In this paper,nonlinear faltung filtering and multiple regression methods are adopted to remove the interference influence in observation data of the ratio between nitrogen and helium.Then the information amount of interval probability of the observation data is calculated.The relationship between the information amount and the earthquakes that are the 1981 Ningjin M S5.8 earthquake and the 1983 Heze M S5.9 earthquake is analysed.It is shown that the high anomalous values of the information amount appeared about two monthes before the two earthquakes.And the information amount returned to normal value after the earthquakes.
