可适用于磨料行业多种物料的加工，如：绿碳化硅、黑碳化硅、石榴石、白刚玉、金刚石、棕刚玉、石英砂等，还可超细高纯加工氧化铝、莫来石、铝钒土等，同时可用于各种高硬、高纯物料的加工，如：玻璃砂、陶瓷熔块、工业硅、锂、钴、锆、各种耐火阻燃材料、化工原料等等。

The study of the forms of hydrogen in diamonds not only enriched the contents of mantle mineralogy, material sciences and gemology, but also provided some important informations for dealing with some problems concerning the Earth's mantle and core.

对金刚石中氢的研究可以丰富地幔矿物学、宝石学及材料科学等的研究内容，并可为解决地幔乃至地核的许多疑难问题提供线索。

the way to drilling whole core at deep and thick layer is a difficulty in hydropower exploration. in present 10 years, by the sm plant glue drilling techniques, both the core adopt rate and drilling rate are improved. by the accumulation of practice experience and adjustment of technical parameter and confectmeasure, this drilling techniques get perfectly.

对深厚卵石层钻探完整取芯样问题一直是水电勘探中的一大难题，近十年来由于采取了sm植物胶金刚石钻进工艺，岩芯采取率和钻进效率都有一定的提高；随着实践经验的积累和技术参数、配制方法的不断调整，此钻进工艺得到了不断完善。

The high quality nanocrystalline diamond film is successfully deposited by double bias voltage nucleation and grid bias voltage growth.

在HFCVD系统中施加栅极偏压和衬底偏压，采用双偏压成核和栅极偏压生长的方法成功制备了高质量的纳米金刚石薄膜。

A positive grid bias and a negative substrate bias voltage s are applied to the self-made hot filament chemical vapor deposited system.

在HFCVD系统中施加栅极偏压和衬底偏压，采用双偏压成核和栅极偏压生长的方法成功制备了高质量的纳米金刚石薄膜。

Dry grinding is the stone used in the polishing process of a grinding, mainly by the resin and synthetic diamond particles.

干磨片 是石材在抛光过程中使用的一种磨片，主要由树脂和金刚石颗粒合成。

The high speed or super-high speed grindings force has the same variety regulation contrast to the common speed grinding, which can get the explanation from closely empirical formulas. Under the same grinding condition, the grinding force of laser trimming wheel is near to or slightly lower than the mechanical trimming wheel.

高速磨削力与普通速度磨削力具有相近的变化规律，这可从它们相近似的磨削力经验公式得到解释，在同一磨削工况下，激光修整砂轮的磨削力接近或略低于金刚石滚轮修整砂轮。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
