查询词典 diamond

Diamonds are the hardest natural material. Only a diamond can cut another diamond. So diamond cutters use diamond dust on a device called a polisher's wheel.

钻石是自然界最坚硬的物质，只有用钻石才能切割钻石，所以，钻石切割机是将钻石沙放在一种叫磨光器的轮子上。

The lattice relaxation in the CVD diamond thick films were detected by the X-ray diffraction attachments. It is associated with self-annealing of diamond thick films in the process of long time deposition. The wearing discrepancy of diamond coated cuttings and diamond thick films brazed cuttings is well illustrated by means of lattice relaxation.

用X射线衍射仪的薄膜附件测试分析金刚石厚膜内的晶格松弛现象，发现沉积金刚石厚膜过程中存在高温自退火的作用，运用晶格松弛的观点很好地解释了金刚石薄膜涂层刀具与厚膜钎焊刀具的耐磨性能差异。

The research results showed that resin bond could hold the self-sharpening diamond more tightly than ordinary diamond, for CSD diamonds have irregular shape, rough surfaces and many incurvated angle. Under the condition of the same grinding efficiency, the grinding ratio of resin bond grinding wheels made with self-sharpening diamond was 1.6 times as high as that of the grinding wheels made with ordinary diamond.

试验结果表明，由于CSD形状不规则，有许多凹入角和粗糙表面，树脂结合剂对CSD的把持力较普通金刚石强，所以在磨削各参数相同的条件下，自锐性金刚石砂轮与普通金刚石砂轮相比，其磨削比提高60%以上。

Syntheses of diamond with a high concentration of nitrogen in laboratory provide a means for fabricating diamond with nitrogen concentration and form similar to those of the natural diamond and for fabricating diamond with "boron skin and nitrogen core".

合成具有完整晶型的高氮含量金刚石能提供一种人工合成类&天然&金刚石和&硼皮氮芯&金刚石的开创性技术。
