动摩擦

Now, there're tens of manufacturers, including Yangdong Stock which produces small-bore (80, 85) multi-cylinder diesel engineers; Jiangsu Shuangdeng Power Supply which produces valve-controlled sealed lead-acid battery, sealed traction battery and gelled battery; Jiangsu Feichuan Stock which produces gear and auto parts; Jiangsu Gangyang which produces crankshaft connecting rod assembly of motorcycle engine; Jiangsu Yafang Cooling which produces medium and heavy duty truck air conditioning system; Jiangyan Sutai Friction Material which produces clutch facing, brake block and brake band; and Jiangsu Pacific Precision Forging which produces cold precision forging, cold extrusion special-shaped part and gear.

现有生产厂家数十家，主要是生产80、85小缸径多缸柴油机的扬动股份有限公司；生产阀控密封铅酸蓄电池、密封牵引蓄电池、胶体电池的江苏双登电源有限公司；生产齿轮、汽车零部件的江苏飞船股份有限公司；生产摩托车发动机曲轴连杆组件的江苏罡阳股份有限公司；生产中重型卡车空调系统的江苏亚方制冷有限公司；生产离合器面片、刹车片、刹车带的姜堰市苏泰摩擦材料厂；生产冷精锻、冷挤压异形零件、齿轮的江苏太平洋精密锻造有限公司等企业。

Further study of this paper has shown that reason for"camel peak"phenomenon in the adhesion-creep test curves is difference between sliding-and static coefficient of friction and discussed the analytic formulae for line contact as well as one direction slip and special correction Lemk's method for point contact when their change is considered as stage jump function.

通过进一步的理论研究指出造成轮/轨粘着率与弹性滑移率实验曲线呈"驼峰"状的原因是滑动区和粘着区的动、静摩擦系数变化，给出了当它们为阶跃变化时线接触条件下的解析解和对点接触情况的独特的"修正"Lemke算法。

The sound of a boot scraping against cold stone.

那是靴子与石头摩擦的声音，还有斗篷拂动的声音。

And with virtual prototyping technology, dynamic behavior of the contactor can be gotten.

该文针对一种新型带反馈的智能接触器，提出了2组周期性相互转换的方程组，耦合了电路、电磁场和可动部分摩擦的影响，并采用虚拟样机技术，研究其闭合的动态过程。

In fact the reason of the invalidation of the parts is not the dehiscence but the move parts and the connect mechanism"s wears. It"s said that 80% of the parts invalidation dues to the wears.

在机械结构的实际工作情况中，导致机械失效的主要原因并不是零部件的断裂，而是动联接和机件的摩擦损坏，80％的机械失效是因为磨损导致的。

The work of media in the granular material into the functioning of friction, dynamic testing, static face seal

工作介质中有颗粒状物质，运转中进人摩擦副，探伤动、静环密封端面

This paper studies the control problem of nonholonomic dynamic systems with unknown inertia parameters, dynamic and static friction terms and other disturbances.

本文讨论了一类带有未知惯性参数、动静态摩擦及外界干扰的非完整动力学系统的控制问题。

For the problem of parameter variation and nonlinear dynamic friction compensation, a recurrent-neural-network-based adaptive- backstepping control for servo system was proposed.

针对伺服系统的系统参数摄动和非线性动态摩擦补偿问题，提出基于递归神经网络的自适应反步控制系统设计方法。

In the quiet of that place even the voice of the surf is reduced to a whispered echo and the sounds of the forest are but the ghosts of sound--the faint sighing of evergreen needles in the moving air; the creaks and heavier groans of half-fallen trees resting against their neighbors and rubbing bark against bark; the light rattling fall of a dead branch broken under the feet of a squirrel and sent bounding and ricocheting earthward.

置身于此地的宁静之中，连拍岸的海浪声也减弱为喃喃的回响，而森林之声也宛如声之幽灵——四季常青的松针在风中微微叹息；半倒的树靠在邻树上，树皮互相摩擦发出阵阵咯咯声和更重的呻吟声；被松鼠踩断的枯枝掉地后反复弹动，发出轻微的嘎嘎声。

Furthermore, the connection between two sesamoids and metacarpal was a kind of soft tissue connection which seemed like fabric, it could exist mini-motion between two sesamoids and metacarpal, resulting in the increasing friction between the tendon of flexor pollicis longus muscle and sesamoids. Meantime, it could lead to metacarpophalangeal joints dislocation and injury the tendon sheath of flexor pollicis longus muscle.

而且，籽骨和掌骨之间没有骨性连接，为纤维软骨样软组织连接，导致籽骨和掌骨之间可以微动，拇指屈伸时，籽骨和掌骨间的微动导致拇长屈肌腱与籽骨摩擦进一步加大，籽骨易脱位，产生籽骨嵌顿于掌指关节，造成拇长屈肌腱狭窄性腱鞘损伤。

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
