普通涂层的磨损机制为微切削；纳米涂层在轻载(10 N)下，以塑性变形为主要磨损机制，随载荷增加至30 N，纳米WC粒子不能起到阻抗陶瓷球对磨副的磨削作用，而是随粘结相一起被去除，同时由于纳米涂层脱碳导致的层间结合薄弱，在滑动磨损中易发生成片剥落，耐磨性大幅下降。

The major etiology of cubital tunnel syndrome is chronic injury with sustained compression of ulnar nerve around elbow joint.

结论］肘部的创伤及慢性劳损可以导致肘管弓状韧带出现肥厚增生，引起尺神经卡压磨损，这是肘管综合征最常见的病因；其他病因还包括慢性骨关节炎，占位病变和先天异常；尺神经可被机械性卡压和磨损，出现慢性缺血缺氧，导致肘管综合征的发生；详细的体格检查和术前的肌电图检查是诊断肘管综合征的主要手段，在诊断时应注意该病与其他部位迟发性尺神经麻痹的鉴别。

In fact, we have been making and membership card making format for 787mm×542mm products, feed to those that were wear plates, but also smoother on both sides; now, when we have a large number of business card printing and membership card making format for 880mm×620mm products, sheet transfer paper and carry it to live in the tooth to tooth row imprint drum within the feed plate shoulderpieces for evenlessness, paper will bow up through the scenic route business card printing and membership card making and then handed over to the transfer paper drum, skinpass paper again, thus causing a scenic route along the first and second color imprinted cannot accurately echoes caused by coincideut.

本来，我们畴前一屈制卡和会员卡制作幅背为787mm×542mm 的产物，输纸台不活的洋间被磨损了，但两侧还较裂缝；此刻，当我们不小度制卡和会员卡制作幅背为880mm×620mm的产物时，递纸牙把纸弛叼住往不抬印滚筒牙排边送时，由于输纸台不活不服整，纸弛两端便弓起来，不纬第一色制卡和会员卡制作后再转交传纸滚筒时，纸弛又复兴了裂缝，从而不离变成第一色和第二色痕迹不克不及不确轻合而引起轻影。

So ,the temperature is quite essential for an engine to produce power .No engines can work well without suitable operating temperatures .If the engine runs too hot ,it may suffer form pre-ignition,while the air-fuel change is ignited prematurely from excessive combustion chamber temperature.Viscosity of the oil circulating in an over heating engine is reduced.Hot oil also forms varnish and carbon deposits may be drawn into the combustion chamber where it increases HC emission.This also causes poor performance and premature wear ,and may even result in engine damage.What is more,the behavior of the metals at excessively high temperature also differs from that at normal temperatures and can produce a condition in which the metal deforms slowly and continuously at a constant stress,If the engine runs too cold, the fuel will not vaporize properly.If liquid fuel reachees the cylinders,it will reduce lubrication by washing the oil from the cylinder walls and diluting the engin oil.This causes a loss ofperformance, an inrease in HC emissions, and premature engine wear.

所以，温度是很有必要的引擎来产生电力，没有引擎，可以工作，如果没有合适的操作温度，如果发动机运行太热，它可能遭受的形式预点火，而空气燃料的改变是点火过早过量燃烧室temperature.viscosity的石油流通的过度加热发动机是reduced.hot油价也构成了清漆和碳存款可能会被拖入燃烧室而增加hc的emission.this也造成业绩不佳和过早磨损，甚至可能导致发动机damage.what更重要的是，行为的研究金属在过高的温度也有不同，在正常温度下，可以达到的一个条件，其中金属变形速度缓慢，不断在恒应力，如果发动机运行太冷了，燃料价格将不会汽化properly.if液体燃料reachees气瓶，将减少润滑洗油从气缸壁和稀释器oil.this造成损失ofperformance ， inrease在hc排放，发动机过早磨损。

The results show that in the applied load range of 10250 N, the mass loss rate of coated AZ91D alloy can be identified to three stages, which are related with whether the coating is worn out. Abrasion is the main mechanism for the coated alloy. The friction coefficient of the coated alloy during sliding wear appears oscillation before it reaches a constant value, which is close to the μ value of the matrix alloy. The mass loss rate of coated alloy increases slightly with increasing applied load when the applied load is more than 150 N because of high plastic deformation accommodation on the matrix alloy surface.

结果表明：根据载荷大小，涂层处理后AZ91D镁合金的磨损行为明显分为3个阶段，这些阶段同陶瓷层是否磨穿密切相关；微弧氧化涂层AZ91D镁合金的磨损机理主要是磨粒磨损；受表面状况的影响，陶瓷涂层的摩擦因数在 0.20~0.45 间波动；在较高载荷下，涂层被磨穿后，涂层的摩擦因数趋于基体合金的摩擦因数，涂层合金的表面变形能力提高，该阶段质量磨损速率随载荷增加，趋势变得缓慢。

While a ball mill is working, balls in the mill are lifted, and then are thrown away with a certain velocity to collide raw material. But at the same time, balls and underboarding are also got collision which may make balls and underboarding fracture. Considering the tough lubrication condition and dust and prills have easy access to meshing zone of gears, the heavy abrasion on gear surface often appears in the upstage gear of open-gear transmission of ball mill.

当球磨机正常运转时，磨球被提升到一定高度后抛落，以一定的速度对物料产生冲击而粉碎物料，同时也对磨球和衬板自身产生冲击，这可能造成磨球和衬板的破球磨机的末级开式齿轮传动，由于润滑条件差，粉尘、金属颗粒容易进入啮合区，齿面常常出现严重磨损，导致齿廓形状发生变化，最后因齿厚磨损过多而折断。

But no one concerned about these horses, their big bony pates were set on their necks like sticks, some parts hollow deeply around the eyes, when they exerted their strength, the fragmentary yellow teeth could be found from their opened mouths.

可是这几匹牲口却没人关心它们。瘦骨嶙峋的大脑袋安在木棍一般的脖子上，眼睛上面都有深窝。它们使劲时，从咧着的嘴里都可以看到被磨损得残缺不全的黄色牙齿。

The saddle of bearing the weight is equipped on train between roll axletree and swiveling frame, under the train's operation long time later, some parts will be abraded easy, then will affect the train's kinetic capability, so must detect the pivotal parts term.

承载鞍安装在货车的滚动轴承和转向架侧架导框之间，承受和传递着各种载荷，在货车长期运行作用下，某些部位是很容易被磨损的，对车辆的动力学性能会产生较大的影响，因此需要对承载鞍的关键尺寸进行定期检测。

The oils Meguiar's uses are also important in maintaining the original condition of the paint by filling in the naturally occurring microscopic pores and surface imperfections thus preventing detrimental substances and elements as simple as water, or worse, acid-rain, from entering into these pores and microscopic surface imperfections thus causing oxidation and chemical etching.

美克拉使用的机密油在维持漆面的原始状态也是重要的，它靠著将自然产生的细微气孔和表面缺陷填充起来以防止有害的物质或成分(如简单的：水或更糟的：酸雨)进入这些气孔或细微的表面缺陷里而造成氧化或化学蚀刻，这些油份会把漆面上原始的树脂在自然过程中被磨损掉的部分取代掉

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
