The Study of the Dynamical Process and the Model of Earthquake Prediction
【摘要】 地震的孕育、发生和发展是地球介质内微裂纹系演化的动力过程 ,包含线性成核扩展阶段和临界增长阶段 ,后一阶段涉及到裂纹系的非线性增长与涨落耗散 ,并当达到某个临界点时 ,即开始单一裂纹的支配过程而发生地震
【Abstract】 The genesis,the development and the occurrence of the earthquake indicate a dynamical process of the micro-crack clusters’ evolution in the medium of the Earth.This dynamic process includes the stage of linear-nucleation expansion and the stage of critical development.The latter is concerned with the non-linear development and rising-dropping dissipation of the micro-crack clusters.When critical development reaches a certain critical point,a single crack will dominates the evolution process.Then,the earthquake happens.
