在激波管中,经反射激波再次压缩的⑤区气体,可以达到比入射激波后的②区更高的温度和压力。而且,气体相对于实验室坐标是静止的,很适合于对那些没有气动要求的高温气体物理化学性质进行测量。因此,除②区外,这是又一个可供实验的高温高压气体平衡区。 In the shock tube, the ⑤ zone gas recompressed by the reflected shock wave can reach a higher temperature and pressure than the zone ② after the incident shock wave. Moreover, the gas is stationary with respect to the laboratory coordinates and is well suited for the measurement of the physicochemical properties of hot gases that are not aerodynamically demanding. Therefore, in addition to ② area, this is another experiment for the high temperature and pressure gas balance zone.
