摘　　要：By two successive linear transformations,a singularly perturbed differential system with two parameters is quasi-diagonalized. The method of variation of constants and the principle of contraction map are used to prove the existence of the transformations.By two successive linear transformations,a singularly perturbed differential system with two parameters is quasi-diagonalized.
