| 摘 要： | 多年来的观测和分析表明,影响沂水泉氡值变化最大干扰是降雨。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量的变化特点,讨论了这种信息熵量的变化与区域应力场的调整变化的关系。

| Abstract: | Observation and analysis for many years show that the precipiation is the greatest disturbance affecting the variation of water radon in Yishui spring.Because there exists "memory" lag influence in this disturbance,such an influence is difficult to be completely removed by using the general relative analysis.In this paper,the disturbance is better removed using convolution integral method.The variation characteristics of information amount of water radon in Yishui spring before and after Heze Ms5.9 earthquake is analysed.The relationship between the information amount and adjustment variation of regional stress field is discussed. |
