A stable is crystalline if it has prolonged-selection purchase. Once the positions of an atom and its neighbours are identified at a single issue, the spot of each and every atom is thought specifically throughout the crystal. Most liquids absence extended-variety buy, Though quite a few have brief-selection purchase. Quick vary is described as the initial- or 2nd-closest neighbours of the atom. In lots of liquids the initial-neighbour atoms are arranged in the same construction as during the corresponding good period.
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 crystal structure concentrates on how the atoms are organized In the crystal. On the other hand, crystallographers are interested in the overall shape and measurement of the crystal as well as its external characteristics. To accomplish this, they have to know about the crystal process.
Include to phrase checklist Incorporate to phrase list C2 [ U ] transparent glass of very superior quality, commonly with its surface area cut into fragile styles
条痕颜色：无色。矿物粉末的颜色叫条痕。它可以消除假色，减弱他色，保留自色，是比矿物的颜色更为可靠的鉴定特征之一。
Encyclopaedia Britannica's editors oversee subject matter locations where they've substantial awareness, no matter if from several years of encounter gained by focusing on that written content or by way of research for an advanced diploma. They produce new content and validate and edit content been given from contributors.
水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。
There's a identical directive about crystal glass which differentiates between complete guide crystal, direct crystal and crystal.
Meanwhile, to be certain continued guidance, we're exhibiting the internet site without the need of types and JavaScript.

. The second layer is shaded inside the figure. It's got a similar plane-triangular construction; the atoms sit during the holes formed by the main layer. The 1st layer has two equivalent sets of holes, though the atoms of the 2nd layer can occupy only one set. The 3rd layer, labeled C
Molecular Crystals: Total molecules are bonded to each other in an arranged way. A good example is usually a sugar crystal, which is made up of sucrose molecules.
This Assessment chronicles around 20 years of research into creating a genetic code for crystal engineering. As opposed to directing biological read more processes, this code uses synthetic forms of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which almost each facet of the resultant constructions might be systematically managed. In just this conceptual framework, the structural and functional advances are described in order to determine the existing degree of sophistication and also to forecast foreseeable future directions on the System.
水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
