| 摘 要： | 利用重建动力学相空间的方法，通过对水氡时间序列计算其关联维数，处理了北京管庄井１９７４－１９７８年。四川姑咱泉１９７４－１９７８年及云南洱源井１９７８－１９８２年水氡日均值资料。结果表明水氡时间序列具有分数结构，在正常情况下，其吸引子维数在５．５０左右。并且发现在地震前降维变化。显然这种降维变化对地震预报是有意义的。

| Abstract: | This paper made use of the way to reconstruct the dynamic phase space and applied the computation method of the associational dimention, to process the daily mean data of the water Radon recorded at Guanzhuang well, Beijing and Guzan spring, Sichuan Province from 1974 to 1978, and at Eryuan well, Yunnan Province from 1978 to 1982. Results show that the time sequence of water Radon variation displayed a fractal structure and an obvious reductuon of dimensional variation before the events. In normal circumstances, the fractal dimensional value (D) is 5.50 or so. Obviously, such a feature is of important significance for the earthquake prediction. |
