金刚石

Allour products named First Brush roller in china enioy high reputation among our customer .Recently years,wehave developed many new new kinds of coating ruller roller ,sponge roller which are well recognized and pleased by all our customers .Our aim is to provide our

近年来与中科院合作的&纳米尼龙刷辊&，3M不织布刷辊，3M千年辊，光刻涂布胶辊，金刚石、陶瓷磨料刷辊等产品广泛用于电子、冶金、木工、玻璃、食品、印刷、石材等行业并受到了广泛的好评。

The "rubbing" and "ploughing" action should be generated between the glass and the glass powder during seaming and grinding.

It is the first time to study serially brown spots on diamond from Hunan. and have found the method of faded brown.

三、首次对金刚石表面的褐斑特征进行了系统分析，找到了去除褐斑的方法，认为褐斑是辐照成因。

Comparatively regular cryst-al shap , high strength , belonging to middle grade but contain more regular cr-ystal shape.

晶形较规则，机械强度较高，是中等品级含较高比例完整晶形的金刚石。

Diamond single crystals were synthesized at a cubic press under high-temperature and high-pressure with the sheeted powder metallurgical iron-based catalysts, which were added by moderate copper powder.

以铁、镍单质金属粉和适量的电解铜粉为原料，采用粉末冶金方法制备规格为Φ15×0.5mm的片状铁基触媒，在六面顶压机上高温高压合成金刚石单晶。

mm的片状铁基触媒，在六面顶压机上高温高压合成金刚石单晶。

The results show that in the case of {1 0 0}, the morphology of crystal changes from lowtemperature sheet to hightemperature tower with increasing the synthesized temperature, whereas in the case of {1 1 1} the change trend is contrary to {1 0 0}. When {1 1 1} facet or {1 1 1} was used as the growth facet, the sheetlike crystal is more difficult to incorporated for the metal inclusion regardless of synthesized temperature. With NiMnCo metal as solvent, large highquality gemgrade diamonds can also grow on {1 1 1} facet with proper temperature gradient.

结果表明：随着合成温度的升高，用{1 0 0}面生长出的晶体形貌由低温片状逐渐过渡到高温塔状，而用{1 1 1}面生长出的晶体形貌变化趋势则相反；采用籽晶{1 0 0}面或{1 1 1}面生长晶体，无论合成温度高低，包裹体都不容易进入片状晶体内部；只要存在合适的温度梯度，NiMnCo触媒同样适合利用籽晶{1 1 1}面生长优质大尺寸宝石级金刚石（≥4 mm）。

The experimental results show that when with the proper technical parameter, we can grow the high quality diamond films with low limitation and slippy and compact surface.

结果表明在适当的工艺参数下可以生长出具有低缺陷、表面平整致密，高质量的(100)面金刚石薄膜。

The super slippy surface can be got after colored metal and non-metal is cut by single crystal diamond cutter. Following, it can take the place of super precision grinding, the efficiency can be increased, and the precision can be guaranteed.

使用精密的单晶金刚石刀具加工有色金属和非金属，能够直接切出超光滑的加工表面，这样就可以取代超精密磨削等精加工工序，极大的提高加工效率，同时也可以保证加工精度和加工表面质量。

I waded in the water and dunked a little and stood looking up at the splendorous night sky, Avalokitesvara's ten-wondered universe of dark and diamonds.

然后我趟进海里，潜入水中再站起来仰望天上缤纷灿烂的夜空，由黑暗和金刚石所构成的观世音十方大千世界。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
