| 摘 要： | 本文采用模糊集理论与分形理论相结合的模糊分维方法，计算了聊城１井水氡和豫０１井水位动态资料，发现在１９８１年河北宁晋Ｍｓ５．８，１９８３年山东菏泽Ｍｓ５．９和１９８５年河北任县Ｍｓ５．０地震前出现了明显的降维特征。选出了两台项的模糊分维基值为０．６０和０．７５。分析结果认为，模糊分维值反映了地震前兆时序观测资料的结构变化特征，具有一定物理意义。做为地下流体前兆观测资料提取地震异常信息的新方法，有一

| Abstract: | By using of fuzzy division combining fuzzy set and fraction theories, the variation materials of Liaocheng No. 1 water radom and Yu No. 1 water level are analyzed, discovering that fraction reduction was happened before the earthquakes of Ningjin Ms5.8,1981,Hezhe Ms5.9,1983 and Yinxian Ms5.0,1985.The fuzzy division base value of the two wells is chosen to be 0.60 and 0.75.The result shows that the fuzzy fraction value can response the structural variation of earthquake forewarning time sequence materials. |
