岩石破裂度M_R及其在地震孕育演化研究中的应用

The rock rupture degree M R and its application in research for earthquake preparation evolution

比较逾渗模型对磁相变与岩石破裂过程的处理方法， 深入探讨了逾渗模型处理岩石破裂过程的本质含义， 指出逾渗模型处理的是联接性相变问题， 它提供了临界点相变的一个简单图像和比较容易理解的途径。逾渗模型与临界点相变的经典模型之间的映像为研究许多现象提供了一种简便可行的方法。逾渗模型对岩石破裂问题的处理不仅仅是现象上的类比， 也有其深刻的物理内容。在此基础上引入岩石破裂度 Ｍ Ｒ 的概念，

On the basis of papers[12,13]we compare the treatment methods by the percolation model for ferromagnetic phase transition with that for rock fracture. The essential meaning of treatment with the percolation model for rock fracture processes are investigated. It is pointed out that the imaging between the percolation model and classical model of critical phase transition provide a simple effective method for studying a great deal of phenomena. The treatment with the percolation model for rock fracture is not only a phenomenological analogy but also having profound physical contents. On the basis of this,the rock rupture degree M R has been introduced to research the possibility of the application of the percolation model for rock fracture and earthquake preparation evolution.
