摩擦着的

Decreasing the parts' surface roughness, as it is shown after a long time practice that can realize the reliability and stabilization of the match; can reduce faction coefficient, wear, stress concentration, vibration, noises, and power consumption; can improve the operative precision and perceptivity; can increase the support area and contact intensity; and also can improve wear degree etc.

长期的生产实践表明，降低零件的表面粗糙度，对保证配合的可靠性和稳定性；对减少摩擦系数，降低动力消耗；对提高机械和仪器的工作精度和灵敏度；对增大支撑面积，减少磨损，提高接触刚度；对减少应力集中，增加耐疲劳强度，减少振动和噪声等均起着重要的作用：即表面粗糙度直接影响着机械和仪器的使用性能和使用寿命。

Such failure is due to the accumulation of toner than age at first, so that the toner can not produce a position to enter the toner, and the waste toner in粉仓will continue to "squeeze" caused by "powder leakage" phenomenon, Then, as the toner contains纸灰, fiber and other filth, more rough, and long cartridge friction, and more tight, the pressure increases, eventually the surface of photosensitive film cartridge has been worn away, cartridge will be ruined.

产生这种故障的原因是起先废粉堆积过满，使再产生的废粉无法进入废粉创仓，而废粉仓中的废粉也会不断"挤"出来而产生"漏粉"现象，接着，由于废粉中包含着纸灰、纤维等脏物，较粗糙，与硒鼓长时间摩擦，而且越来越紧，压力越来越大，最终将硒鼓表面的感光膜磨掉了，硒鼓就损坏了。

The shearing failure of structural plane is considered to be corresponding to the maximum of real contact area, a criterion is given to distinguish the shearing failure of structural plane and a new select method of shear strength is brought forward subsequently; Examine the influence of geometrical features and thickness of weak intercalation on the integrative strength of weak structural plane based on the composing of basic strengths, formative mechanism of shearing plane and failure pattern; and present the quantitative relation between the strength and thickness.

You're unembarrassed by your shoe size emblazoned on the back of each heel, undistracted by all the bright silk shirts, the skirl of rolling balls on shellacked and waxed lumber, the soft jets of air to dry your fingers so they slide like sex in the customized holes, the little numbers glowing everywhere. You sip the air like pilsner, size up the quantum physics of the lane, aim straight into the vacuum at the edge of your life, distant dead end of the imaginary alley where all of us stand cringing in a wedge.

你不为 刻在每只鞋底的尺码感到尴尬；你不为那些发亮的丝的衬衣分神保龄球在手摩擦蜡和虫胶地板滚动声音尖锐喷气使你的指头干爽好让它们有如性爱般滑进那定做的球孔细小的数目字四处闪呀闪你呼吸空气像啜饮比尔森啤酒你计算保龄球巷的量子力你瞄准前面的真空是你生命的边缘远处你幻想的小巷是死胡同我们所有人一一站着排成楔形

The results show that the composite coating is metallurgically bonded to the substrate and the microstructure is fine and uniform. The hardness of the composite coating is up to 400 HV, which is 2.5 times that of the substrate. Under room temperature and oil lubrication condition, the sliding wear tests indicate the friction coefficient and weight loss of the composite coating are smaller than those of substrate. The worn surface of the composite coatings is much smoother than that of the substrate, without grooves and crater.

结果表明，复合材料涂层与基体形成良好的冶金结合，微观组织细小、均匀；复合材料涂层硬度达400HV，约为基体的2.5倍；在室温油润滑条件下，滑动磨损试验表明复合材料涂层摩擦系数和失重均小于基体，磨损表面划痕较浅且平滑，无明显的犁沟、粘着、剥落现象；激光表面合金化显著提高了材料的耐磨性。

The results show that there is a kind of oxide wear at medium temperature and the oxide wear is important to the semimetallic friction material.

结果表明，中温下半金属刹车材料的氧化对摩擦磨损性能起着较为重要的作用，中温下的氧化磨损为其主要的磨损机理。

In the dry sliding experiments of composites, friction coefficients decreased with the increase of load. Plastic deformation happened in the worn surface where Fe element was found, so PAM micro-fiber supported part of the load and prevented the further deformation. On the condition of high speed and high load, the worn surface of PAM1/nylon 6 composites was nearly melted and formed comparative uniform transfer on the surface of steel, which accounted for the rather low wear mass loss. The infrared analysis showed that the a small quantity of transition of crystal form from α into γ of nylon and its composites happened during the friction because of the high temperature and strong sheering strength.

通过对复合材料耐磨性能研究表明：复合材料的摩擦系数随载荷的增加而逐步下降，且磨损表面有明显的塑性变形；从能谱分析结果来看，复合材料表面有Fe的存在，表明PAM微纤承受了部分载荷，并阻止了基体的进一步塑性变形及粘着转移；在高速高载时，PAM1/尼龙6磨损表面处于粘流态，并在钢环表面形成了连续的转移膜，表现出较好的耐磨损性能，且在高温和强剪切力的作用下，材料基体发生了少量的α晶体向γ晶体的转移。

Despite receiving statistically identical trust signals from givers, the massaged trustees with their higher oxytocin levels returned a whopping 243% more than their unrubbed counterparts.

除了统计从授予者那里辨别并接受的信任暗示，被按摩的受信任者带着更高的催产素水平回到他们的拍档身边，比起未受摩擦的拍档，他们惊人的催产素水平高出了243%。

All seem to be leaving, and in their desperation, they do not leave smears or scratches, and they can only make noises by confliction, by rubbing the surface with their unsmoothness, and by resisting the relative motion.

同样的真切，但是都不可逮，都在离去。留下的，也就是一种离去的痕迹。不是什么污渍或者划痕，而只能是一些噪音。离去的，以不平的表面摩擦另一物体的表面，抵制着相对运动。

Slurry pumps are widely used for mining. Suffering from running liquid, their covering plates, volutes and vanes are easily corroded and worn, and the mechanical efficiency decreases to failure in a short time.

渣浆泵是矿山选矿车间重要的机械设备，由于矿浆的冲刷、摩擦和腐蚀的作用，渣桨泵的前后护板、蜗壳和叶轮等过流部件表面受磨损和腐蚀非常严重，短时间内就造成机械效率下降直至完全失效，严重影响着矿山的正常生产。
