摘要
作者对BTW模型进行了简单修改,得出了系统构型的运动方程,进而构建了系统的广义势函数,讨论了广义势在临界点附近的渐进形式,得出了颗粒系统的临界变化规律和临界指数,并提出了一些需要改进的意见。
On the basis of nonequilibrium phase transition standardized model which has universal significance, we have discussed BTW model, which is simply modified, and get a generalized potential function in the neighborhood of the critical point, A group of universal critical exponent relations and universal categories in granular assemblies are derived. Finally, some suggestions are put forward to solve the problem existing in the current theory.
