碳化硅

Accordingly, silicon carbide mirror manufacturing technology has been a focus of attention in optical engineering.

因此，碳化硅反射镜的制备技术成为近几年光学工程领域的研究者们关注的焦点之一。

The result shows that the wearing ability of the compound material is superior to that of the basis alloy and with the increase of the amount of carborundum, it is gradually enhanced.

结果表明：复合材料的耐磨性高于基体合金，随碳化硅含量的增加，其耐磨性逐渐增强。

Taking a carborundum brick of which the thermal conduction coefficient was given as specimen, the measuring error of it is less than 8%.

通过测量已知导热系数的碳化硅砖的导热系数，得其误差小于8%；通过对同一试样的两个小试样进行平行测量，得其相对偏差小于3%。
