unsteady shock wave的意思|示意

The results show that the shock wave structure is unsteady in shock induced hypersonic turbulent separated flows, generating an intermittent region.

结果表明：在激波诱导的高超音速湍流分离流中，激波结构是不稳定的，产生一个间歇区域。

The unsteady flow, structure of waves and mechanism of the forming of shock wave in pressure wave refrigerator are investigated in the present paper.

对压力波制冷机内非定常流动过程、波系结构、激波形成机理等进行了探讨。
