【Abstract】 In this paper, difference equations based on the principle of Conservation are given. Theymay be employed for more complex cases, because the mesh points and mesh regions can bechosen more arbitrarily. The SOR-Newton method is used for solxing the nonlinear differenceequations. This paper also points out in theory and practice that the "Optimum" relaxationparameters, like those in the SOR method, may be obtained in iteration process.更多还原
