摘要
本文提出了一种一维震源孕育模型。用数学物理方法分析了该模型在地震前的孕育过程和各种物理量的变化规律,提出了震源孕育的追赶模式。追赶模式对纵波速度、地壳运动的前兆异常可作出解释,说明该模式是研究地震前兆的一种可能的力学基础.
In this paper,the authors have proposed a one-dimensional model for the development of the source of an earthquake.On the basis of this model,the process of development of the source of an earthquake and the characteristics of variation of some physical quantities before the earthquake are analyzed by methods of mathematical physics.From the results,the"Pursuing Model"for the development of the source of an earthquake have been proposed.Finally,with this model,the causes of anomalous changes of longitudinal wave velocity and crustal deformation,etc.can be explained.It is shown that the pursuit model is a possible mechanical basis for the further study of precursory phenomena of earthquakes.
