水晶原石观赏石充分体现了天然水晶的本质，经过抛光的水晶原石观赏石，玲珑剔透、晶莹璀璨，独具匠心的设计，恰到好处地显露出水晶的魅力。如果您想单纯的欣赏水晶，水晶原石观赏石是你的不二之选，给人一种返璞归真的感觉。
A fundamental notion in crystal constructions is definitely the device cell. It's the smallest unit of quantity that permits identical cells to get stacked together to fill all space. By repeating the pattern from the device cell repeatedly in all Instructions, your complete crystal lattice is usually made. A cube is the simplest example of a device cell. Two other illustrations are demonstrated in Figure 1. The main will be the unit mobile for your face-centred cubic lattice, and the 2nd is for any body-centred cubic lattice. These constructions are explained in the next paragraphs.
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
How Crystals Form The whole process of forming a crystal known as crystallization. Crystallization frequently happens each time a good crystal grows from a liquid or Option.
, has precisely the same construction, but there are two alternatives for selecting the holes that the atoms will occupy. The third layer is often placed over the atoms of the 1st layer, generating an alternate layer sequence A
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。
The elements are found in a number of crystal packing preparations. The most common lattice buildings for metals are Individuals obtained by stacking the atomic spheres into probably the most compact arrangement.
In the meantime, to make sure continued aid, we've been exhibiting the positioning devoid of styles and JavaScript.

. The second layer is shaded from the figure. It's the identical airplane-triangular structure; the atoms sit while in the holes shaped by the 1st layer. The main layer has two equal sets of holes, although the atoms of the next layer can occupy just one established. The 3rd layer, labeled C
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。
《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”
crystal Alteration is variable: absent in several crystals, in others generating dense sericite aggregates which can clearly show some recrystallization outcomes to supply coarser-grained white mica. With the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are occasionally organized in aggregates. Through the Cambridge English Corpus On top of that, haloarchaeal cells ended up embedded in salt crystals beneath laboratory situations and subsequently analysed by light microscopy. Within the Cambridge English Corpus The white clouds (ordinarily sparse) were being also greatly thought to be staying composed of little crystals of water ice, somewhat like cirrus in our ambiance. From the Cambridge English Corpus They can be found in evaporite salt lakes and might be trapped in salt crystals in the course of evaporation. Through the Cambridge English Corpus Therefore, the cells (organelles and membranes) are ruined mechanically by ice crystals, bringing about death through cell lysis. From your Cambridge English Corpus The crystals were being Utilized in the main or second orders of reflection. Within the more info Cambridge English Corpus Inside our 8xperiments, the crystals were cubes by using a base spot of 8 e mm. In the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : influence of temperature and tension.
