| 摘 要： | 本文讨论了信息维D_1用于描述具有场特征的地震前兆图象的可能性以及具体方法。为了计算操作方便,提出了信息维定义的改型公式,对两种不同的实际资料作了计算,结果证实用信息维来描述这类前兆图象是适当的。初步阐述了“降维过程”作为一种系统破坏的整体模式,具有普适性。指出:降维过程中的最小值点可能是孕震过程由中期向短临过渡的转折点。

| Abstract: | The possibility and specific approach describing seismic precursory pattern with field feature using information dimension D_1 is discussed, and both observational and experimental data are processed. The results show that it is suithale to describe this kind of pattern by using information dimension. It is pointed out that the decreasing dimension process, as an integrated model Of system collapse, would be of universality, and that the minimum in decreasing dimension process would be a critical point at which the seismogenic process transits from medium term to short and immediate term. |
