【Abstract】 The features of the numerical solution of partial differential equations in dynamical system have been analyzed in this paper.It finds that the stability of the numerical solution of partial differential equations depends on the values of initial conditions,systematic functions and iteration step length in solving the partial differential equations with the numerical methods.If the appropriate values of the above three factors are given, the chaos phenomenon can be made. Otherwise, the stable numerical solution of the partial differential equations would be out of reach.更多还原
