quasi-fundamental mode

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。

These modes have obviously oscillations in temporal domain, in which the foreshore mode has mainly quasi period about 4 days, while the quasi period for the beach berm mode is 2 8 days.
