金刚石

The experimental results indicate that the diamond films are dense and well crystallized, and the different cubo-octahedral geometry shapes for different growth factor.

实验结果表明，金刚石薄膜比较致密并且晶形比较完整，不同生长因子对应不同立方体-八面体几何形状。

This kind of quartz stone cutting tool is a technological innovation product, the design structure is novel, it change the use of sole grade grinding compound which is already a traditional manufacture method, it simultaneously used the rough and fine grain grinding compound in the cutting tool different part, ie, by the electricity chromium welded skill, weld the large grain diamond grinding compound on the tool bit top (4050 #) and weld the tool bit both sides the metal polish fine grain grinding compound which the nominal grade value is one level up smaller than large grain grinding compound 100-120

这种石材切具属一项技术创新产品，设计结构新颖，这在于它改变了使用单一粒级磨料的传统制作方法，而是在切具刀头不同部位同时使用粗细粒磨料，也就是在刀头顶面和刀头两侧由电铬焊合艺分别同定粗粒金刚石磨料(4050目)和标称粒级值小于粗粒磨料一级以上的金属抛光用细粒磨料100-120目

The former general with corundum and silicon carbide abrasive, while the latter such as diamond and cubic boron nitride superabrasive made.

前者用刚玉和碳化硅等普通磨料，后者用金刚石和立方氮化硼等超硬磨料制成。

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。
