根据赫兹接触模型和经典碰撞理论，并考虑返向器与螺母的固连关系，建立了滚珠与返向器碰撞接触的力学模型，导出了碰撞力公式，并在考虑弹性恢复系数的基础上推导出了碰撞接触时间公式。

The collisions of rigid bodies is a classical problem, however, the coefficient of restitution is used in the conventional researches to study this problem. The authors present a new way for this kind of problem. A theory of the collision between two rigid bodies in two dimensions, taking account of friction, is proposed according the Newton first law. And the shortages of former researchers are justified.

In the second part, we have considered the polariton system described by the model effective Hamiltonian involving single mode photon field interacting with a transverse optical phonon in a more realistic form. On this basis, we have discussed the dynamical evolution of the wave function , the dynamical variables and the non-classical properties for the system in a analytic form for the first time.
