Singularly perturbation inner layer problems for a class of quasilinear second order differential equation with two parameters were discussed.Under appropriate conditions,specific upper and lower solutions were constructed,then prove the existence of the solutions;and the asymptotic estimate of solutions was given according to the theory of differential inequality and the correction of interior layer.
