Background/Objectives: This article discusses the problem of refraction of the shock wave with finite amplitude at contact discontinuity between two ideal gases is non-linear, and can be solved numerically for both stationary two-dimensional and transient one-dimensional cases. Methods/Statistical Analysis: Here considered the problem of interaction of one dimensional shock wave (weak and strong) with the contact surface dividing two different gases with different chemical composition and temperature. The interface surface is considered parallel to the shock wave surface. Findings: The sound speed maximal increase in the layer after the contact discontinuity by means of the gas selection with minimal molar mass and its heating seems to be the most satisfying technical solution for the shock wave suppression. Applications/Improvements: This work can be used for both solution of the problem of the intense explosion shock wave attenuation, and the problem of optimal organisation of detonation combustion, where the wave attenuation at the interface should be minimal.
