为了解葛洲坝泄水建筑物混凝土抗冲耐磨的性能，我院进行了抗冲磨试验。
A number of tests were carried out to study the behavior of abrasion resistance of the concrete used in the sluice buildings of the Gezhouba Project.
结果表明：经化学成分调整后中铬抗磨白口铸铁可成功用于生产中等或中等稍强磨损工况下使用的渣浆泵，成本低，耐磨性优良。
The results show that the modified abrasion resistant medium chrome white cast iron can successfully be applied to slurry pumps which should work under medium or medium-high wear duties.
因此研究磨粒磨损的机理，探索造成机器磨损失效的原因，寻求有效而经济的耐磨材料和抗磨技术是一项刻不容缓的任务。
Therefore, it's an essential task for us to research the principle of abrasive wear, find the reasons of abrasive wear and invent a kind of effectively and economically method.
