quasi-optical waves

Firstly, waves propagation in ID quasi-periodic system is studied by means of the transfer matrix method.

首先, 研究了声波在一维准周期系统中的传播问题.

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。

Due to the waves emitted by perturbed black holes there are no normal mode oscillations but instead of quasi-normal mode ( QNM) frequencies, with the real part representing the actual frequency of the oscillation and the imaginary part representing the damping.

由于波被扰动黑洞散射，使得不存在正规模振荡方式，取而代之的是似正规模，其频率的实数部分表示振荡的频率，虚数部分表示衰减的快慢。
