Abstract: By using the shock theory and the matching principle, under appropriate conditions, the shock problems for a class of nonlinear equations are considered. The expressions of the shock solutions and the shock locations are obtained. The result is applied to the model for a class of compressible fluid flow. And the shock behavior of the solution for the model is obtained separately.

Key words: Nonlinear, Compressible fluid flow, Shock, Matching principle
