硅酸盐

It is not known how rare this resemblance is, or whether it is most often seen in inclusions of silicates such as garnet, whose crystallography is generally somewhat similar to that of diamond; but when present, the resemblance is regarded as compelling evidence that the diamonds and inclusions are truly congenetic.

现在尚不知这种类似稀少到何种地步，也不知道是否它最常见于象石榴石一类的硅酸盐内含物中，而这类物质的晶体结构普遍地在某种程度上类似于金刚石的晶体结构。但一旦存在，这种类似就被视作极有说服力的证据，证明金刚石与内含物确是同源的。

The author analyzed total oxygen content, nitrogen content in steel made by typical process and the inclusion composition, change rule, morphology and distribution qualitatively and quantitatively by image analyzer, big sample electrolysis, SEM and energy spectrum analysis. The results showed that final inclusion form was small granule MnS, calcium aluminate, a small quantity of silicate and lumpy Al2O3. By intensifying deoxidation alloying process control in converter, argon blowing and slagging control and desulphuration and calcium reduction operation in refining course and overall-protection casting, the oxygen content was reduced by 20% above averagely, nitrogen content was reduced by about 10% and the inclusion content was reduced by 30%.
