Not all crystals are Similarly crystalline. There will often be impurities, along with the ionic & covalent in between molecules can develop vastly unique buildings away from exactly the same content. An awesome example of this are diamonds and graphene.
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。
水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。
Most strong products found in nature exist in polycrystalline kind rather than as a single crystal. They are actually made up of numerous grains (modest crystals) packed with each other to fill all space. Just about every person grain has a different orientation than its neighbours. Although very long-vary get exists within one particular grain, for the boundary in between grains, the buying adjustments way. A typical bit of iron or copper (Cu) is polycrystalline.
断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
无色水晶与无色长石因折射率和密度十分接近故较难区分。主要方法是放大检查。长石有两组极完全解理，显微镜下可见两组解理相交而成的“娱蛤状”包裹体或细直的纹理，而水晶则无解理发育，仅有时可见断续不规则的裂理。
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
The weather are located in many different crystal packing preparations. The most typical lattice structures for metals are People received by stacking the atomic spheres into essentially the most compact arrangement.
A lot of crystals behave like butter in that they're hard at lower temperatures but comfortable at larger temperatures. They're known as solids whatsoever temperatures underneath their melting level. A possible definition of a strong is an object that retains its shape if remaining undisturbed. The pertinent difficulty is just how long the thing keeps its shape. A hugely viscous fluid retains its condition for one hour although not a calendar year. A good need to retain its shape lengthier than that.
22Working from what America by now appreciates about itself, the bureau's authorities together with other demographers offer an irresistible, if clouded, crystal ball amid their visions.
Single crystals of metals are gentle and malleable, though polycrystalline metals here are tougher and more robust and are more handy industrially. Most polycrystalline components might be designed into significant one crystals right after extended heat procedure. Up to now blacksmiths would warmth a bit of metallic to really make it malleable: warmth helps make a number of grains improve substantial by incorporating lesser types. The smiths would bend the softened steel into shape and then pound it awhile; the pounding would make it polycrystalline once more, increasing its energy.

水精：水晶为何称为水精，《广雅》有巧解：�?水之精灵�?”；李时珍则说：�?莹洁晶光，如水之精英 ”。细加考究，此称还蕴含浓厚的宗教意味呢。水精一名，最初见于佛书，后汉支曜翻译的《具光明定意经》说：�?其所行道，色如水�?�?。
水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光，都可以在包裹体水晶种找到缩影。
