磨痕 meaning in English
polishing scratch; grinding crack
Examples
- Are your shoes scuffed
4鞋上有磨痕？ - The 2014 aluminium alloy treated by 500 solution and 165 ageing has fine alloy phases distributing equably , higher mechanical properties , thus the wear resistance is improved
经500固溶和165时效处理后，其合金相分布细小、均匀，力学性能较高，磨损时，在出现了犁沟的同时，还存在粘著剥落坑，磨痕最浅，耐磨性提高。 - It is different from under point contact that there is no stick area under line contact in the partial slip regime , and load distribution within line contact area is uneven due to roughness of surface
磨痕分析表明，承载区域接触不均匀，存在虚接触区域，其大小与表面粗糙度有关，而接触区域没有不磨损的粘着区，不同于点接触形式。 - In addition , this article also researched the friction marks of steel ball after long - time friction tests with sem images and spectrum analysis , and summarized the principle how to reduce friction and wear of three prescriptions
另外,本文还利用sem图像和能谱分析等手段,对长磨试验后的钢球磨痕情况进行了研究,归纳总结出了三种配方的减摩抗磨和自修复机理。 - 3 . calculating the portion and area of different wear form made by wear methenism with a coding method based on the margin element . and judging the action degree of wear methanism . 4
运用一种基于边素的图像轮廓编码方法，应用图像外围轮廓的编码法计算出不同磨损机制造成的磨痕形状所占的面积及在整个磨损主体中所占比重，判断磨损图像不同磨损机制的作用程度。
