1·The abrasive grain is impregnated in nylon.

磨粒在尼龙中浸渍而成。

2·With the increase of grinding speed or the abrasive grain size of the grinding belt, the grinding rate increases.

提高砂带速度、工件转速以及增大砂带磨粒粒度可有效地提高花岗岩的磨削效率。

3·Abrasive grain makes up only 30% weight; its self-sharpening action is weaker, resulting in lower grinding efficiency.

磨粒只占总重的30%；其自锐性弱，因而磨削效率很低。

4·What is the abrasive grain being used, aluminum oxide, silicon carbide, zirconium etc? - Especially for the last pass.

问我们打磨用的砂是什么材料的，氧化铝？金刚砂？

5·Our hand pads are cut from industrial quality non-woven nylon, impregnated throughout with abrasive grain and boned with heavy duty resins.

手磨片由高档的尼龙纤维做基材，专业的树脂将磨料均匀的粘固在基材上。

6·For the two kinds of abrasive grain-ordinary abrasive and ultra hard material, carborundum and diamond were chosen as samples for dispersing experiment.

针对两大类磨料微粉——普通磨料和超硬材料，选择碳化硅和金刚石为例进行分散实验。

7·The influences of abrasive grain size, belt speed, contact roller's hardness, grinding depth and grinding feeding speed on surface roughness were discussed.

讨论了砂带粒度、砂带线速度、接触轮硬度、磨削深度和磨削进给速度对表面粗糙度的影响规律。

8·The stress and grinding mechanism of a single magnetic abrasive grain in the magnetic abrasive finishing are analyzed. The required properties and preparation technologies of MAGS are discussed.

分析了磁力研磨加工过程中单个磁性磨粒的受力状况和磨削机理，论述了磁性磨粒的性能要求和制备工艺。

9·A method for detecting the protrusion height of diamond abrasive grain on diamond wheel was proposed based on the digital image identification technology, and the measuring system was established.

提出一种应用数字图像识别技术检测金刚石砂轮磨粒凸出高度的检测方案，并建立了测试系统。

10·Natural or artificial abrasive powder or grain, on a base of textile material, of paper, of paperboard or of other materials, whether or not cut to shape or sewn or otherwise made up.

砂布、砂纸及以其他材料为底的类似品，不论是否裁切、缝合或用其他方法加工成形。
