摘要

利用模糊集理论与分形理论相结合的模糊分维方法 ,处理了山东聊古 1井水氡 1 0多年来的观测资料 ,找出了水氡模糊分维值的 3次较大变化与相应 3次地震的关系。在这 3次地震前水氡模糊分维值都出现明显地小于 0 5 7的低值异常变化。这可能反映了系统在较大地震前的明显降维特征
Based on fuzzy fractal method combining fuzzy set theory and fractal theory, the data of water radon content observed for more than 10 years at the Liaogu 1 well in Shandong Province were analysed and a relation between the three large variations of the fuzzy fractal of water radon content and there corresponding earthquakes was found Obvious low value anomalous variations with radon content fuzzy fractal values well below 0 57 appeared prior to all the three earthquakes This fact might have reflected the characteristics of obvious fractal decrease of the system prior to rather large earthquakes
