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。
Observations and analyzes over the years show that the greatest disturbance affecting the radon change in Yishuiquan is rainfall. Due to the “memory” lag effect caused by such interference, it is difficult to exclude this effect by using the general correlation analysis. This paper uses the convolution integral method to eliminate this effect well. The characteristics of the information of radon in Yishui spring before and after the Ms5.9 earthquake in Heze are analyzed. The relationship between the change of information entropy and the adjustment and adjustment of the regional stress field is discussed.
