求翻译：振动与反馈，持球期间因球拍和球碰撞所造成的底板 floor往复运动称为振动，传导至握拍手的通常称手感，通过空气传导的为听感。反馈性好的，球感清晰，振幅小，周期短。反之，则球感模糊，震手。反馈性对运动员击球期间的技术调整有较重要的作用。是什么意思？

Vibration feedback, backplane floor reciprocating motion caused by the ball during the collision of bat and ball as vibration transfer to the grip clapping usually known as the feel, the sense of hearing by air conduction. Feedback and good sense for the ball clear, small amplitude, short period. On

With vibration feedback, racket ball and ball for the period as a result of the collision between the backplane floor reciprocating motion, vibration is called conduction to grip the clapping his hands feel, is often referred to by air conduction hearing.
