文移

采用步进电机驱动滑板移动可使该相移器实现相移，在移动中相移器保持较好的匹配性能，文中相移量化精度可为1°

Second , the using of step motor to drive the inserting-fin can realize the phase shift . During the movement , this phase Shifter remains a good matching performance , and its phase shift precision realizable can be 1 °

当加热强度变化时，可激发产生东移的开尔文波和西移的Rossby波重力波。

The change of heating strength will arouse east move Kelvin wave and west move Rossby wave .
