光洁程度

这两个步骤的平衡与合成效应决定了总去除率和表面光洁程度。

The balance and compositive effects of two steps decide the total removal rate and its surface degree of finish .

跑合后的钢领表面具有比光面钢领更高的光洁程度，磨损系数仅（2.3±1.3）×10~（-7），其理论寿命至少可在一年以上。

After the running-in period , the surface of the ring presented even higher surface finish than the polished one . The wear coefficient K was rather small for the values ( 2.2 ± 1.3 )× 10 ~ ( - 7 ) .

对硅钢厂、冷轧厂连续退火炉所用碳套辊、石英陶瓷辊的形貌与显微结构进行了分析，认为表面的光洁平整程度与孔洞的形状影响辊子的使用寿命；

The contour and microstructures of the carbon or quartz ceramic rollers used in the continuous annealing furnaces in the Silicon Steel Sheet Mill and the Cold Rolling Mill are analyzed .

本机制成的颗粒硬度高、表面光洁、内部熟化程度较充分。

The granule production have high hardness , smooth surface , fully degree of internal maturation .
