研究了奇异值的大小与基流的非线性稳定性和不稳定性的关系.结果表明,它们两者之间存在很好的对应关系;奇异值的大小随着基流的稳定性(不稳定性)加强而变小(增大).稳定情形下最大奇异值明显小于不稳定情形下的最大奇异值.
The relationship between the size of singular value and the nonlinear stability and instability of the base flow is studied. The results show that there is a good correspondence between them. The magnitude of the singular value varies with the stability of the base flow Sex) increases and decreases (increases), the maximum singular value in the stable case is obviously smaller than the maximum singular value in the unstable case.
