Stochastic Cahn-Hilliard equation is an equation of the field theory for solving the Non-equilibrium dynamics problem in a weak state and is a case of nonlinear Langevin equation.In this paper,using the ackward difference method(BDM),a numerical solution of the stochastic C-H equation is proposed and using the Ito formula,probability and the martingale theory,the convergence of the numerical process is proved in the meaning of mean square. 相似文献
