本文对在接触面上的物体“飘”起来的原因进行探讨,认为是由于某些原因导致接触面对物体的支持力减小,直至完全消失,从而飘离接触面.
In this paper, the reason why the object “floating” on the contact surface is discussed is that it is due to some reasons that the support force of the contact surface to the object is reduced until it completely disappears, and thus departs from the contact surface.
