Results show that the equivalent mass in normal direction depends on the modes of collision. In the case of reversed sliding and sticking, the coefficient of restitution varies as a result of the instantaneously changes of the equivalent mass during impacting process. The coefficient of restitution depends not only on the contact force, but also on the kinematical and dynamic parameters of the two rigid bodies. Moreover, a formula is proposed to calculate the coefficient of restitution.

Into a disk, I observed careful about the rotation of the disk and head movements to the piece, under the advance and retreat into the situation, such as motor and found that the rotation of the disk normal, the motor did not act in big problem, but components in the empty head or disk, the sliding pole in the slide is very difficult to switch off the power supply, pushing gently with his hands under the head of several components to slide in the poles, there is clear sense of the hysteresis.

放进一张碟片，笔者仔细的观察了一下碟片的旋转及光头给件的动作，下进等电机的进退情况，发现碟片的旋转基本正常，电机的进退也没太大问题，反而光头组件在空载或加碟片的情况下，在滑动杆上滑动十分吃力，关掉电源，用手轻轻推了几下光头组件使其在杆上滑动，有很明显的迟滞感。

Secondly, considering the complexity and heterogeneity of rock-like materials, two new models, namely the Inner Open Sliding Crack Model and the Single Wing Crack Model , are proposed.
