其它描述：《庶物异名疏》中说： �?水精出大秦国，一名黎�?�?。结晶完整的水晶晶体，就如参差交错的马齿，所以人们又叫它马牙石。先民们最早用它研磨成眼镜片，因而送它一个眼镜石的绰号。水晶有通称，也有俗称。广州一带称水晶叫晶玉，又名鱼脑冻；江苏东海县山民发现水晶会 �?窜火�?�?，于是给它起个放光石的俗名。世间一物多名，不足为奇，而像水晶拥有这么多的别称，实不多见。瞧，从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等，简直构成一部奇石鉴赏史。

③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。

These developments include exotic structures with programmable lattice symmetries and nicely-described crystal behaviors, responsive supplies that leverage the intrinsic Attributes of nucleic acids to manipulate constructions on demand, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals that offer insights into light–make a difference interactions. Searching ahead, we challenge the Neighborhood to leverage the remarkable structural control afforded by crystal engineering with DNA to synthesize classes of purposeful resources that thrust further than what has actually been probable with The natural way happening crystalline elements or People made by much more typical strategies.

If you need to see how crystals are shaped, you may do some challenge in the pretty individual kitchen and see the formation in the crystals arise with the possess eyes . This may be accomplished by Placing a little quantity of table salt click here into some frequent faucet water, wait around 24 several hours, and you will see awesome cubed formations. This comes about because the h2o is evaporating, which leads to the atoms that make up the salt (the mineral) and also the drinking water to come back closer jointly.

Fig. four: Creating blocks with various shapes and floor chemistries direct the development of distinctive crystal symmetries.

结晶�?When sea water is permitted to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。

时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：

Crystals could be grown under moderate problems from all ninety two naturally transpiring aspects other than helium, and helium is usually crystallized at very low temperatures by utilizing twenty five atmospheres of stress.

水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：

英语-中文（简体） phrase #beta Beta /beta #preferredDictionaries ^chosen title /picked /preferredDictionaries

There's two such achievable periodic preparations. In Every, the 1st layer has the atoms packed right into a aircraft-triangular lattice in which every atom has six quick neighbours. Figure two reveals this arrangement for your atoms labeled A

在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。

水晶观赏石是天然水晶中最具代表的作品，具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值，而水晶观赏石只需要将表面进行抛光，即展现出晶体内所包裹的物质，直接欣赏原汁原味的水晶石。
