①磨粒的数量(浓度、大小)：反映了磨损的程度。•②磨粒的尺寸、形状：反映了磨损的类型(型式)。

(1) the number of abrasive particles (concentration, size): the degree of wear is reflected. (2) the size and shape of the abrasive particles: reflecting the type of wear (type).

如：细长的磨粒——切削(磨粒磨损)；细小而非常多的磨粒——腐蚀磨损；球形磨粒——滚动疲劳磨损；表面粗糙，有拉毛、擦伤痕迹的磨粒——严重粘着磨损等。

Such as: slender grain - cutting (abrasive); small and very abrasive, corrosive wear; spherical abrasive - rolling fatigue wear; surface roughness, a galling, scratches, severe adhesive wear and abrasive.

•③磨粒的成分： 反映了磨粒的来源

(3) the ingredients of the abrasive particles: reflecting the source of the abrasive particles
