润滑的

By designing different test rigs, choosing different friction materials and performing a large amount of tests, the property of friction with respect to the variation of normal loads, relative velocities and lubricational conditions is examined.

通过设计不同的测试装置，采用不同的摩擦材料，通过大量的实验，测试并分析了摩擦力随接触界面间正压力、相对速度、润滑状态变化的情况，研究了摩擦力在预滑动和宏观滑动阶段的静态及动态摩擦特性，发现并提出摩擦过冲概念。

The marine stern tube bearing is a special structure and complicated load sliding bearing, which is always under foul lubricative state in real work, and always produces bad abrasion to get premature invalidation. This brings a great influence to ship s safely sailing and economic benefit.

船舶尾管轴承是一种受力复杂、结构特殊的滑动轴承，它在实际工作中处于极其恶劣的润滑状态下，常常产生严重的磨损而导致尾轴承的过早失效，这对船舶安全航行和营运经济效益带来很大的影响。

CO2 for the compressors lubrification in particular polyolester (POE oil and polyalkylglycol oils there are still uncertainties in the definition of an optimized oil in relation to the various applications.

二氧化碳的压缩机润滑（特别是polyolester功能的石油和polyalkylglycol所油）仍然存在着不确定性的定义，一个优化的石油有关的各种应用。

The results show that increasing the ball numbers and mandrel extension length may reduce the ovalization, but leads to more remarkable wall thinning; the ovalization becomes more severe with the larger bending angle; the smaller the relative bending radius, the larger the ovalization is; the ovalization and wall thinning degrees are both smaller in the case of pressure die with dry lubricant; and under the same bending condition, the ovalization of LF2M tube is larger than the one of 1Cr18Ni9Ti tube.

结果表明，增加芯头个数与芯棒伸长量都能减小弯管的截面畸变，但两者都导致弯管壁厚减薄量增大；随着弯曲角度的增加，截面畸变越严重，相对弯曲半径越小，无芯棒与芯头支撑段弯管的截面畸变愈严重；在压块无润滑情况下，弯管的截面畸变和壁厚减薄量都小，并且在同等弯曲条件下，1Cr18Ni9Ti弯管的截面畸变小于LF2M弯管。

It illuminated that the TiN coating enhanced the load bearing capacity, and enlarged the using range of substrate material. MoS2 coating and TiN+ MoS2 composite coating both possessed the good capability for palliating radial fretting damage. The microslip increased in radial fretting when the solid lubrication coating was used on the contact interfaces. More system energy can be absorbed in this process in favor of reducing vibration.

TiN 涂层明显提高了基体材料的承载能力，扩大了其应用范围； MoS2涂层和 TiN+ MoS2复合涂层具有较好的抗径向微动损伤能力；固体润滑涂层增加了径向微动界面的微滑，并可吸收更多的系统能量，有利于系统的减振。

Girls are often shortchanged in quality as well as in quantity of teacher attention.

一个吱吱做响的轮子得到了教育的润滑就是一个经典的例子。（3）然而，完整的答案并不是男性学生的自信心。

The rise-descent devices there is a innovation lubrication system is outstanding in its ability to prolong bearing and gear's life, hence ensuring high precision positioning and continuous feeding.

此升降装置的润滑系统是技术革新的新设计，在延长轴座与齿轮寿命方面有著显著的能力，由此，可确保高精度的定位及连续的切削。

Results show that MoS2-Ti composite coatings grow in islands pattern, their cross-section appear to be dense columnar structure.

结果表明：不同Ti含量的MoS2-Ti复合薄膜呈岛状生长模式，断面呈致密细柱状，结晶状态均为无定形态；薄膜的显微硬度随Ti含量增加而升高；MoS2-Ti复合薄膜在大气中的摩擦磨损性能优于MoS2薄膜，掺杂适当Ti可以使MoS2-Ti复合薄膜的摩擦曲线波动减小，耐磨寿命提高，在本试验研究范围内，含30%Ti复合薄膜的耐磨寿命最长，当Ti掺杂量达到50%时MoS2-Ti复合薄膜失去润滑性能。

GK31030型高速中厚料三针绷缝机采用齿轮泵内循环自动润滑系统和可靠的密封方式，能保证在高速时的正常运转和衣料的洁净。装有独特的移动护针机构和上轴外支座，使其增强了缝厚能力。具备基本缝、单边压平缝和拼接缝的双面装饰缝纫功能。

The pumb surface temperature is too high, the oil pressure table index for 0.3, and no oil lubrication "" on: based on the analysis of the causes of that failure is not dumping fuel (due for not getting a loop outflow, cooling and pressure is not enough ESP.).

油泵暗地温度功矮，不雅其油压外洋的指数为0.3，而且不不收油&润滑&障碍阐发与摈斥：根据差这种环境的阐发，觉得障碍的来因仍在于不不收油(变成泵边的油得不到轮回不源不入、加冷且不张力也不敷落矮的本体)。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
