摘要
本文根据几次大震前孕震区形变异常临近地震时的有序性,以B值、C值、H值及R值作为描述有序的指标,研究了大震前有序度时值曲线的形式和特性。发现在主震到来之前,B值和C值会突然上升并持续在高值状态,而熵值H则于此时减小。
In this paper, the examples on ordering of crustal deformation anomalies prior an earthquake in it's preparation region are demonstrated. Then,the temporal feature and forma of the ordering prior an earthquake are discussed by using the index B,C,H and R. It is discovered that the B and C value in a definite region will jump up rapidly and lay in the high position, when the major earthquake is coming. The entropy H of the tide tilt amplitude factor will be reduced in this case.
