Generalized Potential Function and Critical Exponents in Granular Assemblies
Shaohong Cai · Journal of Guizhou University · 2008
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.
