碳硅石

Recently a mantle mineral group including about 70～80 subtipys of mineral have been discovered from podiform chromitite in Tibet,China.

最近在西藏罗布莎村豆荚状铬铁矿石中发现一个由70~80种矿物组成的地幔矿物群，其中包括新矿物罗布莎矿，还有金刚石、柯石英、碳硅石、方铁矿、以及Fe-Si相矿物。

For a 1116Kg chromitite and a 384Kg mantle peridotite sample, by heavy mineral separation and picking up under a binocular microscope following productions are obtained: the UHP minerals including moissanite and over 1000 diamond grains are discovered firstly from the Kangjinla chromitite orebody Cr-11, which is far more abundant than the Luobusa district; a series of unusual mantle minerals like moissanite and a great deal of diamond grains are discovered firstly from the host rocks of chromitite orebody Cr-11, providing the foundation of discussing the chromitite origin and its relation with the host rocks; besides the UHP minerals like moissanite and diamond, various special mantle minerals are revealed from the chromitite orebody Cr-11 and its host rocks including some native elements, alloys, oxides, sulphides, silicates, carbonates, and tungstates.

2人工重砂发现铬铁矿和地幔橄榄岩中的金刚石等特殊地幔矿物。1116 Kg铬铁矿和384Kg地幔橄榄岩大样经人工重砂分选和双目显微镜下挑选矿物，取得如下成果：首次在康金拉11号铬铁矿体中发现了上千粒金刚石，以及碳硅石等强还原环境的超高压矿物，数量远远超过在罗布莎铬铁矿矿区中发现的金刚石；首次在康金拉11号铬铁矿矿体的近矿围岩中发现了大量金刚石和碳硅石等一批异常地幔矿物，为探讨铬铁矿的成因及与近矿围岩地幔橄榄岩的关系奠定了基础；除挑选出金刚石和碳硅石等超高压矿物，在康金拉11号铬铁矿矿体与围岩地幔橄榄岩中还发现了自然铁球、金属互化物、氧化物、硫化物、硅酸盐等一批异常地幔矿物。

Moissanite has not been found in large enough quantities naturally to be used for jewelry.

碳硅石还没有找到足够数量大，自然要为珠宝使用。

This means resetting stones in a moissanite ring is much easier.

这意味着在一个碳硅石环复位石容易得多。

So, moissanite used in jewelry is grown in labs.

因此，碳硅石被用来制作珠宝生长在实验室。

Moissanite is NOT as heat sensitive as most gemstones.

碳硅石是因为大多数的宝石热不敏感。

Moissanite is the best diamond look-alike stone we found.

碳硅石是最好的钻石看起来像石头，我们发现。

They are even more cost effective that moissanite, another faux diamond, as well as being cheaper that many other alternative gemstones.

他们更符合成本效益的碳硅石，另一个人造钻石，以及被便宜很多其他选择宝石。

While moissanite is used in jewelry as a diamond substitute, many experts feel it to be even more beautiful than the gemstone itself.

尽管碳硅石是首饰作为钻石的替代品，许多专家认为它甚至比宝石本身的美丽。

Clean moissanite with a soft cloth or with a ultrasonic cleaner.

清洁碳硅石用软布或使用超声波清洗机。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
