润滑

In the absence of such a high degree of cleanliness, adsorbed gases, water vapor, oxides, and contaminants reduce friction and the tendency to seize but usually result in severe wear; this is called "unlubricated" or dry sliding.

由于无法实现如此高的清洁度，摩擦面中的气体，水蒸汽，氧化物及其他污染物会在此过程中减少摩擦力及咬合的趋势，但也往往导致更严重的磨损；这种情况被称为&无润滑&或干摩擦。

After all, unlike a man with a limp penis, a woman with an unlubricated vagina can still easily begin coitus, if she so chooses.

毕竟，不像阴茎疲软的男性那样，阴道无润滑的女性如果决定进行性交的话，她仍然能够容易地开始性交。

The chemical corrosive wear mechanism of electroless Ni-P coating under unlubricated wear was studied by test and theory and the possibility of as an anti-chemical corrosive wear coating on drill pipe was probed into.

从实验和理论两方面研究了化学镀Ni-P合金在无润滑磨损条件下的化学腐蚀磨损机理，探讨了化学镀Ni-P合金作为钻杆耐腐蚀磨损功能性镀层的可行性。

The microstructure, phases composition and microhardness of the coating were analyzed and measured by SEM, XRD and microhardness testers respectively, and the friction and wear properties of the specimens sliding against Al2O3 ceramic in a ball-on-discmode and under unlubricated condition were investigated.

中文摘要：采用粉末包埋法在P110钢表面制备渗铬层；借助扫描电子显微镜、X射线衍射仪和显微硬度计，对渗铬层的显微组织、相组成和显微硬度进行了分析和表征，并通过无润滑条件下的球－盘式摩擦磨损试验研究了渗铬处理对其摩擦磨损性能的影响。

As a background for introducing rolling-element bearings, a brief review of sliding bearings may be helpful: The simplest possible bearings are unlubricated plain or sliding bearings—like the cart wheels mounted directly on wooden axles in ancient history.

为了介绍滚动轴承，简单回顾一下滑动轴承会对我们有帮助：最简单的轴承是无需润滑的平面或滑动轴承-象古代直接安装在木制车轴上的车轮。
