附录1 外文翻译（英文原文） The Surface Quantity While Machine Processes Abstract:The breakage of the machine spare parts, generally always from the surface layer beginning of.The function of the product, particularly its credibility and durable, be decided by the quantity of the spare parts surface layer to a large extent.Purpose that studies the machine to process the surface quantity be for control the machine process medium various craft factor to process the surface quantity influence of regulation, in order to make use of these regulations to control to process the process, end attain to improve the surface quantity, the exaltation product use the function of purpose. Key word:The machine process the tired strength surface quantity remaining dint Text: A.the machine processes the surface quantity to use the influence of the function to the machine (A)The surface quantity to bear to whet the sexual influence 1. Rough degree of surface to bear to whet the sexual influence A just process vice- of two contact surfaces of good friction, the first stage is rough only in the surface of of the peak department contact, the actual contact area is far small get in touch with the area in the theories, at mutually get in touch with of department of peak have very big unit should dint, make actual contact area creation the mold transform, the flexibility transforms to shear to slice the breakage with of the department of peak , cause seriously wear away. The spare parts wear away and can is divided into three stages generally, wearing away the stage, wearing away the stage normally in the early years and violent wear away the stage. The rough degree of surface is very big to the influence that the spare parts surface wear away.Say a value of surface generally more small, it wears away sex more good.But rough degree of surface the value is too small, lubricant not easy storage, contact of the noodles easy occurrence the member glues to connect, wearing away to increase on t
