Abstract: When there is small quantity term contained in differential equation, we may solve if by using the M.E.Shvez iterative method. If foe small quantity term has singularity, of in foe certain region where foe small quantity term is not small, using this method to solve such differential equation, we may meet difficulties. In this paper,the author improves the M.E.Shvez method. Several examples are given to demonstrate the algorithm.
