Not all crystals are Similarly crystalline. There are often impurities, and also the ionic & covalent in between molecules can produce vastly various structures away from precisely the same material. An incredible 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。
天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
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。
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。
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：
损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。
Amongst the binary crystals, the best buildings to visualize are These with equivalent figures of The 2 varieties of atoms. The structure of sodium chloride is based on a cube. To construct the lattice, the sodium and chlorine atoms are put on alternate corners of a dice, and the composition is recurring (Figure 3B).
晶体 Silicon crystals developed in a very laboratory transform light into electrical Electricity. 在实验室中长成的硅晶体可将光线转变为电能。
say cheese a thing that someone that is taking a photograph of you lets you know to mention so that the mouth tends to make The form of a smile
The sodium chloride crystal lattice is characterized because of the close packing with the favourable sodium ions and destructive chloride ions. Each sodium ion is surrounded by six chloride ions, and each chloride ion is surrounded by 6 sodium ions, making a hugely steady and symmetrical composition.
crystal, any sound material wherein the part atoms are arranged inside a definite pattern and whose surface regularity reflects its inner symmetry.
crystal Alteration is variable: absent in lots of crystals, in Some others developing dense sericite aggregates which may present some recrystallization results to make coarser-grained white mica. With the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes arranged in aggregates. Through the Cambridge English Corpus Also, haloarchaeal cells were being embedded in just salt crystals less than laboratory disorders and subsequently analysed by light-weight microscopy. With the Cambridge English Corpus The white clouds (usually sparse) have been also broadly thought to be staying composed of little crystals of water ice, alternatively like cirrus in our ambiance. In the Cambridge English Corpus They are really found in evaporite salt lakes and will be trapped in salt crystals throughout evaporation. From the Cambridge English Corpus For that reason, the cells (organelles and membranes) are ruined mechanically by ice crystals, resulting in Demise through mobile lysis. Within the Cambridge English Corpus The crystals were used in the first or second orders of reflection. Through here the Cambridge English Corpus Inside our 8xperiments, the crystals were being cubes by using a base area of 8 e mm. From your Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : result of temperature and stress.
