A crystal construction focuses on how the atoms are arranged inside the crystal. On the other hand, crystallographers are interested in the general shape and measurement on the crystal and also its external traits. To accomplish this, they should learn about the crystal technique.

你们都知道,拿起一个水晶棱镜,让一束阳光通过它,就会得到一个光谱,看起来就像一条连续的彩虹色带。
对任何宝石来说,颜色都是非常重要的,水晶也不例外。如果是水晶晶体是有颜色的,如粉水晶、黄水晶、紫水晶等,其颜色评价的最高标准则是明艳动人,不带有灰色、黑色、褐色等其他色调。如粉水晶,颜色以粉红为佳;紫水晶,要求颜色为鲜紫,纯净不发黑;黄水晶,要求颜色不含绿色、柠檬色调,以金橘色为佳。对于发晶来说,晶体的颜色也是很重要的。相同发丝的金发晶,晶体完全无色(白水晶)和晶体略偏茶色,肉眼的视觉观感也是有差别的,所以前者的价格会高于后者。

15The trick to a great thermoelectric product is actually a crystal composition during which electrons can stream 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。
隐晶类水晶外观是一块块的,不是成六角水晶簇状,但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶,因为结晶的体积极为细小,需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑,因为结晶之间有“水化硅石”填补,玛瑙便属于此类。
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 referred to as buckyballs, are quite solid and Practically incompressible. Crystals are more info shaped this kind of that the balls are arranged in an fcc lattice which has a a single-nanometre spacing concerning the centres of adjacent balls. The equivalent C70 molecule has the shape of a rugby ball; C70 molecules also type an fcc crystal when stacked collectively. The reliable fullerenes variety molecular crystals, with weak binding—furnished by van der Waals interactions—in between the molecules.
