Small disturbances are introduced on both sides of a steady, non-dissipative, plane shock wave.

在无耗散介质的定常、平面激波两边产生了小扰动。

The test problem is the initial stage of a two-dimensional diffraction and reflection of a plane shock wave, impinging on a rectangular obstacle.

The features of shock wave can be analyzed qualitatively in the velocity plane for a special perturbed gravitation which is used to simulate the self-gravitation of interstellar gas.

Early ideas suggested blunting the nose of the plane to prevent the pressure waves joining up to form one intense shock wave, or lengthening the plane without increasing its weight to dampen the noise.
