通过对销-盘摩擦磨损试验机的夹具和控制部分进行改进，研制出载流摩擦磨损试验装置，并采用该装置研究了地铁钢铝复合式第三轨与受电靴摩擦副之间的载流摩擦磨损特性，采用激光三维共焦扫描显微镜和电子能谱仪等微观手段，结合电接触理论分析了摩擦副的载流摩擦磨损机制。

A plane quadric crank mechanism consists of four rigid components connected by a rotary pair and a moving pair.

平面四连杆机构是由四个刚性构件通过转动副，移动副联接，且各构件上各点运动平面都相互平行的机构。

Dynamic models of LMRG, the work table system and cross slide table system are presented.

另外，当滚动直线导轨副有节距偏差时，完善后的导轨副静刚度精确计算程序仍然能够进行静刚度仿真计算。

Normally open solenoid valve, coil power after the due role of suction, dynamic core down to the Deputy valve valve plug depressed, GLOBE VALVE vice valve closed, the main valve valve cup pressure rise, when the pressure rose to a certain value, the main valve valve cup Like the upper and lower pressure, due to the role of the electromagnetic force, moving to promote the main valve core valve cup, the clamping main valve seat, the valve closed.

常开电磁阀，线圈通电后由于吸力作用，动铁芯下移，把副阀阀塞压下，副阀关闭，主阀阀杯内压力上升，当压力升到一定值时，主阀阀杯的上下压差一样，由于电磁力作用，动铁芯推动主阀阀杯下，压紧主阀阀座，阀门关闭。

Normally closed solenoid valve, coil power, the GATE VALVES armature under the action of electromagnetic force driving the first Vice-valve valve Seti, the main valve on the valve cup of fluid flow out through the Vice-valve, reducing the role of the main valve pressure on the valve cup, when the main valve valve to reduce pressure on the cup to a certain value, the armature driving the main valve valve cup, and use pressure Ershi main valve valve cup opening, medium flow.

常闭电磁阀，线圈通电后，衔铁在电磁力作用下先带动副阀阀塞提起，主阀阀杯上的流体经副阀流走，减少了作用在主阀阀杯上的压力，当主阀阀杯上的压力减少到一定值时，衔铁带动主阀阀杯，并利用压差而使主阀阀杯开启，介质流通。

In order to investigate the formation and damage of surface films ,electrical contact resistance method was used to monitor the formation of surface films in reciprocating lubricated cylinder bore/piston ring pairs.

为了研究摩擦副中表面膜的形成和损伤状态，用接触电阻法对润滑条件下往复运动的缸套/活塞环摩擦副进行了试验研究，提出了可揭示表面膜状态的表征方法，并成功观测到了磨粒对表面膜的损伤及恢复过程。

In consideration of the difference between two parts,insert blocks on moving half and fixed half were combined;and the compounded core-pulling of slanted pushing rod,dog-leg cam and slide block was applied to finish the demoulding of internal and external side concave.

介绍了1副在同1副模具中注射成型2个差异性较大的塑件的模具结构，该模具设计时综合考虑了2个塑件的差异性，分别采用了动、定模镶块组合的结构形式，并使用斜推杆、弯销与滑块复合抽芯来完成内外侧凹脱模。

I am not just painting, but enjoying the sweetness and bitterness of my dust-laden memory and try to recall everyones childhood and their long lost past.

对我来说每每完成的不仅仅是一副副画--享受它们的过程，回忆童年的甜蜜和酸涩，为了我们遥远的童年还有那些曾经忘却的记忆。

I am not just painting, but enjoying the sweetness and bitterness of my dust-laden memory and try to recall everyone's childhood and their long lost past.

对我来说每每完成的不仅仅是一副副画——享受它们的过程，回忆童年的甜蜜和酸涩，为了我们遥远的童年还有那些曾经忘却的记忆。

Of multinational alums: The vice-president for sales formerly worked at Avon Products Inc., the vice-president for footwear came from Nike Inc., and the chief financial officer left news wire Reuters Group PLC..

事实上，李宁公司拥有一支完全国际化的团队，其主管销售的副总裁来自于雅芳，主管鞋类的副总裁来自于耐克，首席财务长则来自于路透集团。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
