Using an L2 energy method proves that the solutions of the general initial-boundary problem to this relaxation model converges time-asymptotically to a stationary wave or a rarefaction wave or superposition of these two kinds wave for small perturbation.
对此松弛模型，用L~2—能量方法证明了在小扰动的情形下，相应的一般初边值问题的解渐近收敛到一个稳定波或一个稀疏波或这两种非线性波的叠加。

When the motion of the basic state is the shear flow (or the differential rotation), this property means that the unstable waves would evolve automatically into the quasi-stationary stage.
