摘要：

Asymptotic solutions are obtained for the 2D Euler system for non-ideal gases with appropriate boundary conditions which describe the diffraction of a weak shock at a wedge; the non-ideal gas effects are characterized by a van der Waals type equation of state. The behavior of the flow configuration influenced by the non-ideal gas effects, that includes the local structure near a singular point, is studied in detail.
