Abstract:In this Pace, We consider the two species competition model of the first-order nonliner differential equations. By using the methods of multiple scales, the asymptotic expansions of solution is considered,and using the technique of differential inequality we prove the existence of solution of the oriqinal Problem,and give the uniformly valid asmptotic estimation of the solution.
Keywords:Singular perturbation  The methods of multipel scles  Asymptotic expanaion  Differential inequality
