本文对线性稳定性理论作了简要的介绍和评述，重点讨论了非模态效应。的时间和空间框架进行了讨论，并处理周期性和随机强迫的响应。一个扩展到非自治的进化问题。旁路过渡由于二次不稳定的条纹作为一个例子来说明的作用，非模态线性机制的崩溃湍流。
This paper gives a brief introduction and review of linear stability theory with emphasis on nonmodal effects. The temporal and spatial framework is discussed and the response to periodic and stochastic forcing is addressed. An extension to nonautonomous evolution problems is presented. Bypass transition due to the secondary instability of streaks is used as an example to illustrate the role of a nonmodal linear mechanism in the breakdown to turbulence.
