Abstract: In this paper,the author studies the corner and the shock layer bahaviors in secondorder nonlinear systems. Under the appropriate condions, using the theory of differential in-equality, the author gets the existence of the solution and its componentwise uniformly validasymptotic estimation.

Key words: Singular Perturbation, turning point, corner layer, shock Layer, differential inequality
