8Where do we get this magic wand and crystal ball?我们到哪里获得这种魔棒和水晶玻璃球？
23Sometimes, nevertheless, the crystal method of the silicate inclusions is observed to resemble much more closely The inner structure of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
发晶的价值取决于发的颜色、罕见性及大小，一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态，便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值，通过它们可了解几百万年前地球上水的成分及变化。
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。
断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
Lattices could have one particular lattice place for every cell or more than one, yielding a total of 14 Bravais crystal lattice forms. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the three-dimensional array created by a list of discrete details.
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。
To be a warm Resolution cools or possibly a saturated Resolution evaporates, particles draw near sufficient for chemical bonds to variety. Crystals also can kind from deposition directly from the fuel stage. Liquid crystals have particles oriented within an arranged manner, like strong click here crystals, yet can easily move.

晶体 Silicon crystals developed within a laboratory change mild into electrical energy. 在实验室中长成的硅晶体可将光线转变为电能。
用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。
水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟，喜欢将它们摆在家里或办公室里，认为水晶球有灵性，能保平安，带来财运。不过天然水晶不像看起来那么晶莹剔透，它也有瑕疵，我们在选购饰品的时候要注意。此外，我们还要掌握水晶的评价依据、选购方法，这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
The C60 molecules, also known as buckyballs, are very strong and Just about incompressible. Crystals are fashioned this sort of that the balls are organized within an fcc lattice which has a one-nanometre spacing amongst the centres of adjacent balls. The comparable C70 molecule has the shape of a rugby ball; C70 molecules also kind an fcc crystal when stacked alongside one another. The sound fullerenes kind molecular crystals, with weak binding—supplied by van der Waals interactions—amongst the molecules.
