| 摘 要： | 多年来的观测和分析表明,影响沂水泉氡值变化的最大干扰是降雨.由于这种干扰存在着“记忆“滞后影响,所以用一般的相关分析难以将这种影响排除干净,本文采用了褶积积分方法较好地排除了这种影响.分析了菏泽5.9级地震前后沂水泉氡信息熵的变化特点,讨论了这种信息熵的变化与区域应力场的调整变化的关系.

| Abstract: | After observing and analyzing for many years, we know now that the rainfall is the greatest disturbance affecting the variation of water radon in Yishui spring. With "memory" lag influence, the disturbance is difficult to be removed by using general analysis. But in this paper, the disturbance can be better removed with convolution integral method. The variation characteristic of Information Entropy of water radon in Yishui before and after Heze earthquake M5 9 is analyzed. The relationship between the information entropy and the adjustment of regional stress field is discussed. |
