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 results show that the shock wave structure is unsteady in shock induced hypersonic turbulent separated flows, generating an intermittent region.
它代表激波的绝对不稳定性，是新得到的模式。
It is a newly discovered mode and represents an absolute instability of shock.
我们发现对轴对称扰动稳定的吸积流外激波对非轴对称扰动却是不稳定的。
We find that the outer shock solution, which was previously found to be stable with respect to axisymmetric perturbations, is, however, generally unstable to non-axisymmetric ones.
