声光晶体由行波场驱动，声场频率则由系统的反馈讯号控制。

The frequency of the sound wave is controlled by the feedback signal of the system.

用有限差分法进行波场全倾角归位的关键在于波场的延拓方向。

The key to all-dip wave field migration using finite-difference method lies in the continuation direction of wave field.

传感器部位上的下行波场被正向传播到水底，产生水底处的下行 波场（46）。

The down-going wavefield at the sensor position is forward propagated to the water bottom, resulting in a down-going wavefield at the water bottom (46).
