磨损

Comparison was carried out to the conductance of copper graphite material made with traditional method.

为了改善金属石墨电刷的滑动磨损性能，在其中添加少量的铅、锡等低熔点金属是常用的方法[1] 。

The cavity wear of both arc-shaped and cone-shaped was calculated.

以此计算锥形和弧形两种挤压模具型腔的磨损。

It is significant to study on the wear mechanism about conical twin-screw.

因此对用于加工木塑复合材料的锥形双螺杆磨损和使用寿命的研究具有重要的实用价值。

The results show that the brush-plating coating is even and compact from section plane with good toughness and adhesion. The microhardness of the coating is 230.6HV0.5 which is 3 times of cast aluminium substrate. The wear resistance of the coating is 3 times of cast aluminium substrate. But the friction coefficient of the coating is 0.70 which is more high than that of the substrate, which is favorable for the fixed conjugate between the axis sheath and the axis seat of the gear-box.

结果表明，镀层厚度分布均匀、致密，镀层与基体界面清晰，未出现氧化物夹层，镀层的韧性和结合强度均较好；测得碱性铜及铸铝基体的显微硬度分别为230.6、74.2HV0.5；碱性铜的镀制使基体表面显微硬度及耐磨性均提高了2倍多，磨损状况明显改善。

The constant of the function is also determined by our experiment. This method is introduced into the polish process and the materials′ error correction .

通过实验确定了该函数磨损时间常数值并将该方法用于计算机控制的抛光和误差修正。

CNTs composite coatings were prepared on carbon steel plate by high power of continuous wave CO2 laser beam.

研究了在激光作用下，工艺参数对涂层性能的影响，并对复合涂层进行了摩擦磨损试验。

If an object sliding along the contact surface, the two of the contact surface of the convex part of the collision, a fracture, wear, created obstacles to the movement.

如果一个物体滑动沿接触表面来看，两者的接触面的凸角部分的碰撞，断裂，磨损，制造障碍，把运动。

The femoral prosthesis of Corin rotaglide knee replacement system can reduce wearing of prosthesis and loosening. It fits well the young people.

提示Corin Rotaglide全膝关节置换减少了假体磨损和潜在的松动，尤其适合年轻活动量大的患者。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
