quasi-stationary flow的意思|示意

The ray theory of geometric optics was applied to visually investigate the propagation of quasi stationary waves in time mean basic flow and interpret the zonal nonhomogeneity.

应用几何光学中的射线理论，直观地讨论了准定常波在时间平均基流中的传播，解释了定常波传播的纬向非均匀性。

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.

当基态运动为剪切流(或较差旋转)时，这一性质将使不稳定波自动演化到准稳阶段。
