coplanar contact

Thus,the difficulty in observing the plane-plane contact is overcome.

该实验台通过显微镜和CCD图像传感器可以放大拍摄两接触面间的接触情况,同时可通过力传感器测量摩擦力,解决了研究面面接触时,难以观察表面接触情况的问题。

The key to the formula derivation is solving an equation of conjugate-contact condition.

明确了盘形刀具齿形计算的关键是共轭接触条件方程的求解,从而进一步论述了圆弧齿轮盘形刀具共轭条件方程求解的新方法。
