17These rings are indicative of the crystal structure of nickel and can be defined only by invoking wavelike Qualities of sunshine.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度，越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏，就没有利用价值。
10This may be the silicon chip—just a little chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
Tetragonal: These crystals type prisms and double pyramids. The structure is like a cubic crystal, except a single axis is for a longer time than another.
C2 [ U ] transparent glass of quite high quality, normally with its floor Slash into sensitive designs:
, has a similar framework, but There's two choices for selecting the holes which the atoms will occupy. The 3rd layer might be positioned more than the atoms of the main layer, producing an alternate layer sequence A
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。
1A crystal chandelier lit the home.一盏水晶吊灯照亮了房间。《柯林斯英汉双解大词典》
Q.four. Exactly what is the distinction between atomic composition and crystal Crystal structure? Ans. The main distinction between atomic framework and crystal framework lies of their definitions: atomic framework refers to how atoms are arranged inside of a solitary molecule or maybe a cluster of molecules, While crystal framework problems the particular arrangement of atoms inside a good material.
看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。
天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值，但是包裹体水晶观赏石经常需要适当打磨抛光，这样更方便观赏水晶内部的包裹体。
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（growth traces）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
The framework of the sodium atoms alone, or even the chlorine atoms alone, is fcc and defines the unit mobile. The sodium chloride construction So is created up of two interpenetrating fcc lattices. The cesium chloride lattice (Determine 3A) is predicated on the bcc composition; each individual other atom is cesium or chlorine. In cases like this, the device mobile is usually a cube. The third vital construction for AB
矿物成分：针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶，如发晶、钛晶、绿幽灵等，发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶；含铁�?；呈金黄色或柠檬�?)称黄水晶；含锰和钛呈玫瑰色者称蔷薇石英，即粉水晶；烟色者称烟水晶；褐色者称茶晶；黑色透明者称为墨晶。
