A solid is crystalline if it's very long-selection purchase. Once the positions of the atom and its neighbours are identified at one issue, the position of each atom is thought exactly through the crystal. Most liquids lack long-range get, Whilst several have quick-assortment order. Brief array is defined as the very first- or 2nd-nearest neighbours of an atom. In lots of liquids the initial-neighbour atoms are organized in exactly the same structure as from the corresponding strong phase.

看做工：水晶制品加工过程分为两种，即磨工和雕工。如水晶项链、手链、耳环等属于研磨品；观音像、内画鼻烟壶等属于雕刻品。
We've published about above three hundred stones from the mineral kingdom! Examine Just about every stone's one of a kind origin, heritage, and energies below.
根据美国已经了解的情况，统计局的专家和其他人口统计学家在他们的视野中提供了一个不可抗拒的水晶球。
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。
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。

15The trick to a fantastic thermoelectric substance can be a crystal composition where electrons can circulation 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。
There are actually only a few distinctive unit-cell styles, so numerous crystals share one device-cell style. An essential characteristic of a unit cell is the number of atoms it incorporates. The whole number of atoms in all the crystal will be the range in Each individual mobile multiplied by the number of unit cells. Copper and aluminum (Al) Each individual have 1 atom per device cell, when zinc (Zn) and sodium chloride have two. Most crystals have only a few atoms for every unit cell, but there are numerous exceptions. Crystals of polymers, for instance, have Countless atoms in Every single unit mobile.
The structure with the sodium atoms by yourself, or even the chlorine atoms on your own, is fcc and defines the device cell. The sodium chloride construction Hence is created up of two interpenetrating fcc lattices. The cesium chloride lattice (Determine 3A) is based around the bcc composition; every single more info other atom is cesium or chlorine. In this instance, the device cell is actually a cube. The 3rd critical framework for AB
水晶观赏石是天然水晶中最具代表的作品，具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值，而水晶观赏石只需要将表面进行抛光，即展现出晶体内所包裹的物质，直接欣赏原汁原味的水晶石。
