天然的水晶一般都会有絮状(绵绺),也就是大家俗称的瑕疵,这是液体水落石出和二氧化碳的小孔穴,而人工合成的水晶就不会有这样的特征。

10This would be the silicon chip—a bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。

③次生包裹体:指主体水晶形成后,由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。

25If you're a Billy Crystal admirer, you will enjoy this movie.如果你是比利·克里斯特尔的影迷,你就会喜欢这部电影。《柯林斯英汉双解大词典》

当二氧化硅结晶完美时就是水晶;结晶不完美的就是石英:二氧化硅胶化脱水后就是玛瑙;二氧化硅含水的胶体凝固后就成为蛋白石;二氧化硅晶粒小于几微米时,就组成玉髓、燧石、次生石英岩。

水晶原石观赏石,从字面意义理解:观赏水晶石的原貌,即经过抛光去皮后的包裹体水晶和原色水晶,不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高,水晶晶体通透干净,颜色艳丽,意境鲜明深刻的价值就高,它的价值特点就好比钻石,实实在在石头本身的价值。

发晶:无色、浅黄、浅褐等,可因含金红石常呈金黄、褐红等色,含电气石常呈灰黑色;含阳起石而呈灰绿色。

Metallic Crystals: Metals typically variety metallic crystals, exactly where a few of the valence electrons are totally free to move all through the lattice. Iron, for instance, can form various metallic crystals.

颜色:无色,浅至深的紫色,浅黄、中至深黄色,浅至深褐、棕色,绿至黄绿色,浅至中粉红。

15The trick to an excellent thermoelectric product is often a crystal composition during which electrons can flow freely.制造一种好的热电材料的关键是,需要一种电子可以自由流动的晶体结构。

Crystal Lattices There are actually seven systems of crystal structures, which can be also called lattices or House lattices:

⑤、打孔:是在水晶成品未完成前,根据其所需打孔之尺寸及位置,以钻头加工,如制表件、笔筒、瓶孔等。

21You all know the way when you take a crystal prism and pass a beam of daylight by it, you have a spectrum, which looks like a ongoing read more band of rainbow shades.
