摘要: 利用模糊分维计算公式,计算了1983年11月7日山东菏泽Ms5.9级地震和1992年10月22日江苏射阳Ms4.6级地震震中附近的井水位、水氡观测值的模糊分维值。结果表明,地震发生前其模糊分维值有明显的降维现象,异常显示比原始观测曲线异常显示明显。Abstract: The fuzzy fractal dimensions values were calculated from the data of escaped radon and water level in wells in the epicenters and their vicinities of Heze Ms5.9 earthquake, shandong Province,on November 7,1983 and Sheyang Ms4.6 earthquake, Jiangsu Province, on October 22, 1992,by the fuzzy fractal dinension formula, the result showed that there were decreases of fuzzy fractal dimension before earthquakes and the anomalies were more obvious than that of the original observation.
