摩擦的

The value of the stable friction coefficient is equal to the average value of the friction coefficient of matrix and reinforcement.

在摩擦试验的最初阶段，复合材料的摩擦系数随摩擦的进行而降低，并在一定的摩擦距离以后趋于稳定。

Though it is a long history of the research on static friction, many problems, such as relationship between static friction and static contact time, the relationship between static friction and load, and the prediction of static friction coefficient have not yet fully studied.

虽然静摩擦的研究历史很悠久，但仍有一些问题没有解决，如静摩擦与静止接触时间的关系，静摩擦与载荷的关系，以及静摩擦系数的预测等问题。

The coefficient of friction for static contact is higher than for dynamic contact, so static contact provides better traction.

此时因为静摩擦系数比动摩擦系数高，所以静摩擦的附着力较大。

We can reduce friction where it is undesirable, and increase it where it is needed.

我们可以在不需要摩擦的地方减少摩擦，在需要的地方增加摩擦。

The measuring precision of the rotational tribometer is upgraded from the millimeter level to the micrometer level compared with the linearly reciprocating friction test rig, which gives a more profund understanding of friction characteristics and is necessary for developing high precision frition models.

在摩擦预滑动阶段，GBM模型用一系列含库仑摩擦的弹簧振子模拟预滑动阶段的摩擦特性；在宏观滑动阶段，则采用了改进的Bouc-Wen模型和含变摩擦系数的扩展Stribeck曲线。

The main differences among these three test methods were compared, and correlation of evaluation among them were also discussed. The test results showed that the difference of test results is between 0.5 and 1.0 grade, and AATCC test method for wet crocking test showed more color transfer than the other two test methods.

结果表明，对于纺织品耐摩擦色牢度，三种测试方法所测得的耐摩擦色牢度值之间存在着一定的差异，虽然只有0.5~1.0级之差，但对于耐摩擦色牢度是否合格是至关重要的，AATCC湿摩擦的测试结果比其他两种稍显严重。

The test shows that the butt friction welding process of copper and stainless steel bar can be divided into the following stages approximately: the adhesion at the beginning of friction,friction inside the copper,the expansion of the plastic ring and the friction on the bound surface of copper-stainless steel and the friction in stainless ...

结果表明铜与不锈钢棒料的对接摩擦焊过程大致可分为初始摩擦的粘着；铜内摩擦、塑性环扩展；铜、不锈钢界面摩擦及不锈钢体内摩擦3个主要阶段。在接头形成过程中经历了两次摩擦面的转移。其内容对促进异种材料摩擦焊的接头形成机理研究有积极的作用。

The invention provides a low-friction sliding mechanism, a low-friction agent composition, a friction reduction method, a manual transmission and a final reduction gear unit that can exert very excellent low friction characteristics to sliding surfaces present under various applications, and, in particular, that have more excellent low friction characteristics than that of a combination of an existing steel material and an organic Mo compound.

本发明提供低摩擦滑动机构、低摩擦剂组合物、减小摩擦的方法、手动变速器和最终传动减速器，其在不同应用下会对所存在的滑动表面表现出极其优良的低摩擦特性，并且，尤其是其比现有的钢材和有机Mo化合物的组合具有更优良的低摩擦特性。

All the actuators of the three-axis turntable are brushless torque motors, all the bearings are aerostatic air bearings, so the friction caused by these elements can be neglected. The main source of friction is the metal-to-metal friction on the slip rings. Hence the "Columb+Viscous+Static" friction model is used here for analysis.

由于三轴转台的驱动系统选用的是无刷电机，轴承则采用的是气浮轴承，轴系上的摩擦力已大大降低，三轴转台上的摩擦主要是滑环轴上金属对金属的摩擦，所以文中选用&库仑＋粘滞＋静摩擦&的摩擦模型来进行分析。

EDAX and talysurf. There were four wear regimes for KRF/GCI, during the starting friction period abrasion was dominant, when the process of the formation and break of transfer layers was balanced the main wear mechanisms were adhesion and fatigue, mild melt wear was found at higher temperature. For KRF/MMC, the dominant wear mechanisms were ploughing and microcuting during the running-in, when transfer layer formed, the film-film adhesion at the interface became dominant and mild melt wear occurred also at high temperature.

对于KRF/GCI，在摩擦的起始阶段主要是二体磨粒磨损，当表面转移膜的形成与破坏形成动态平衡时，粘着磨损和疲劳磨损是主要磨损机理，摩擦表面温度较高时，产生严重的粘着磨损和轻微的熔融磨损；而KRF/MMC在跑合过程中，SiCp对较软材料的犁削、微切削是主要摩擦磨损机理，转移膜形成后，表面的膜—膜粘着则为主要摩擦磨损机理，高温下也会发生轻微的熔融。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。

Uncovering their weak spots, so I can defeat them.

揭露出他们的弱点，这样我就可以打败他们了。
