One object for another object's surface without sliding or rolling the rolling of the trend, as the two objects in contact with some compression in the deformation of the rolling and obstruction, called "rolling friction."

一个对象的另一种物体的表面无滑动或滚动滚动的趋势，因为两个物体接触一些压缩，在变形的滚动和阻碍，所谓的"滚动摩擦"。

Properly selected slideway dimensions, air pressure and preload create a very stiff, virtually friction free interface.

适当地选取滑轨尺寸，空气压力和预载荷可实现高刚性，无摩擦的滑动。

But his revolution has long since become a shell, a work of theatre in which the old trouper rants on even as many in the bored audience desperately want to slip away—if only they could.

The backwall slides substantially in a contact-less manner within the tubular body, preferebly by way of a reduced diameter of the backwall (11) relative the inner diameter of the tubular body (8), so that it is pushed backwardly when the body retracts radially after actuation.

后壁在管体内作基本上无接触的滑动，最好通过相对管体（8）的内径减小后壁（11）的直径，使在驱动后主体径向缩回时后壁被向后推动。

The results show that the composite coating is metallurgically bonded to the substrate and the microstructure is fine and uniform. The hardness of the composite coating is up to 400 HV, which is 2.5 times that of the substrate. Under room temperature and oil lubrication condition, the sliding wear tests indicate the friction coefficient and weight loss of the composite coating are smaller than those of substrate. The worn surface of the composite coatings is much smoother than that of the substrate, without grooves and crater.

结果表明，复合材料涂层与基体形成良好的冶金结合，微观组织细小、均匀；复合材料涂层硬度达400HV，约为基体的2.5倍；在室温油润滑条件下，滑动磨损试验表明复合材料涂层摩擦系数和失重均小于基体，磨损表面划痕较浅且平滑，无明显的犁沟、粘着、剥落现象；激光表面合金化显著提高了材料的耐磨性。
