论文摘要修改

RT，论文中英文摘要如下。求英语牛人帮忙修改下，谢谢啦。 采用NaOH溶液对金刚石磨料进行了预处理，然后用硅烷偶联剂进行表面改性，并研究了用处理过的金刚石磨料制造的树脂砂轮的磨削比和磨削效率。结果表明，在干磨的条件下，处理后的金刚石磨料对砂轮磨削比的提高显著。通过显微镜观察磨削后的砂轮表面形貌，发现树脂对金刚石颗粒把持力增大，磨粒脱落较少；与仅用偶联剂处理的金刚石砂轮相比，其磨削比提高了50%。 The diamond powder was pretreated by sodium hydroxide solution and modified with silane coupling agent. The grinding ratio and grinding efficiency of wheels which were manufactured with the above treated diamond abrasive were investigated. The results indicate that the treated dimond abrasive enhances the grinding ratio of wheels observably under the dry condition. By observing the wheel surface with microscope after grinding, it can be approved that the pullout strength of resin was enhanced and less abrasive was brushed off. Compared with dimond wheels treated only with coupling agent, the diamond wheels treated with this new method have an increase of 50% on the grinding ratio. |

| The diamond powders are pretreated by sodium hydroxide solution and modified with silicane coupling agent. The grinding ratio and grinding efficiency of resin wheels made from the above treated diamond powders are investigated. The results indicate that the grinding ratio of wheels increases observably by treated diamond powders under the simple grinding condition. By observing the wheel surface with microscope after grinding, it shows that bonding strength between resin and diamond powders increases and abrasive worn off decreases, and the grinding ratio increases by 50% compared to the wheel made from powders treated with coupling agent only. |

| The diamond powder was firstly preprocessed by sodium hydroxide solution. After surface modification with silane coupling agent, it was used to make resin wheels, the grinding ratio and grinding efficiency of which were then investigated. Experimental results indicated that the treated dimond abrasive enhanced the grinding ratio of wheels remarkably under the dry condition. The observation of the grinded wheel surface with microscope also demonstrated that the pullout strength of resin was enhanced and less abrasive brushed off. Compared with processing only by coupling agent, the proposed solution could increase 50% of the grinding ratio of diamond wheels. |
