1·Several kinds of solid polishing agents applied to different polishing process have been made experimentally, using fat and oxide or carbonide as material, and adding some additives.
以油脂类、氧化物或碳化物为原料，添加适量的添加剂，研制不锈钢制品固体抛光剂。
2·Using two kinds of magnification of the metaloscope to observe the zonal carbonide, scientific basis for evaluating correctly the quality of the steel is provided.
用金相显微镜两种不同倍数观察带状碳化物，为正确评定钢材质量提供依据。
3·With the original process, the qualification rate of the liquation carbonide was only 75.
原工艺下液析碳化物合格率仅为75。
