摘要

本文利用从时域地震信号中提取的各种特征值来构造相空间，对四组样本进行计算的结果发现，在该相空间中存在两个“吸引子”：地下核爆炸吸引子和天然地震吸引子．求得吸引子的关联维数均为分数维，且小于相空间的维数．当相空间的维数从低到高增加时，吸引子维数明显出现饱和值；不同吸引子的分维数不同．本文还提出了“吸引中心”的概念，并就吸引子、吸引子维数、吸引中心和吸引域等在核爆地震模式识别中的应用问题进行了探讨．

Abstract

In this paper

the phase space is constructed by various features extracted from seismic signalsin time domain. The results of calculation for four sets of samples indicate that there are two"attractors" in thephase space: one is the attractor for underground nuclear explosion

another is for natural earthquake. The yieldedcorrelation dimension are all the fortal dimensions

and less than the dimension of phase space. When the dimensions of phase space increased ho low to high

the dimensions of the attractors become apparently saturated

and different attractors have different fractal dimensions. A new concept

namely

the "attraction center" isproposed in this paper. Moreover

the attractor

the attractor dimension

and the attraction center with their applications to seismic pattern recognition of undegrund nuclear explosion are also explored.
