secondary instability meaning in Chinese

二次不稳定性

Numerical study for the resonant triad interaction and secondary instability in a two - dimensional supersonic boundary layer
二维超音速边界层中三波共振和二次失稳机制的数值模拟研究
A high frequency secondary instability mode is detected , which rides on the primary instability wave in time domain and appears at the inflectional point of mean streamwise velocity profile
结果表明，高频二次不稳定性在时域上表现为骑在基频波的特定的相位区域。
Experiments are mainly focused on initial growth of unsteady primary instability , high frequency secondary instabilities both in natural condition and artificial high frequency excitation
