| 摘 要： | 用非线性动力学重建相空间的方法对唐山地震前后（１９７１～１９７８年）昌黎地电台和地应力台前兆观测资料分别进行了关联维的计算．结果表明，地电阻率和地应力前兆资料吸引子具有分数维结构，并且发现这两种不同前兆资料的吸引子具有相同的前兆动态变化特征．在计算中发现，地电阻率的分数维具有多层次性．对此还进行了简单的讨论

| Abstract: | The fractal dimensions of earthquake precursor time series(resistivity and stress)which are gained from Changli ground resistivity station and ground stress station before and after the Tangshan earthquake (from 1971 to 1978) are calculated by the method of phase space reconstruction in this paper.The results show that the attractors of these two time series are of fractal dimension structure and the two different earthquake precursor attractos have the same diagnostic variation.It is also discovered that the ground resistivity is of multiple fractal dimension in different character scale,which is discussed in this paper. |
