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。
the good point out of many uncomplicated substances, that have an everyday form and surfaces arranged in related designs
A standard concept in crystal structures will be the unit mobile. It is the smallest unit of volume that permits identical cells to be stacked jointly to fill all Place. By repeating the sample with the unit cell again and again in all directions, the entire crystal lattice can be manufactured. A dice is The only example of a unit cell. Two other examples are revealed in Figure 1. The 1st is definitely the unit cell to get a experience-centred cubic lattice, and the next is for just a body-centred cubic lattice. These constructions are discussed in the following paragraphs.
The ordered inner construction of enormous crystals, such as the fluorite and quartz shown listed here, is reflected inside their geometric designs.
. These four buildings comprise a lot of the binary crystals with equivalent quantities of cations and anions.
, has the same composition, but there are two decisions for choosing the holes that the atoms will occupy. The 3rd layer is usually put over the atoms of the initial layer, producing an alternate layer sequence A
水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
Numerous crystals behave like butter in that they're challenging at very low temperatures but check here delicate at greater temperatures. These are known as solids at all temperatures under their melting position. A achievable definition of a sound can be an object that retains its shape if still left undisturbed. The pertinent difficulty is how long the object retains its shape. A extremely viscous fluid retains its form for one hour although not a yr. A reliable must keep its condition lengthier than that.
看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。
⑥、丝印：水晶表面附有不同的色料进行效果处理，颜色层面较厚，着力后方可脱落。
Crystal Lattices You can find 7 programs of crystal constructions, that are also called lattices or space lattices:
crystal, any good product by which the ingredient atoms are organized inside a definite pattern and whose surface area regularity reflects its interior symmetry.
The C60 molecules, also known as buckyballs, are very sturdy and Practically incompressible. Crystals are shaped these kinds of the balls are arranged within an fcc lattice that has a 1-nanometre spacing in between the centres of adjacent balls. The identical C70 molecule has The form of a rugby ball; C70 molecules also form an fcc crystal when stacked together. The stable fullerenes sort molecular crystals, with weak binding—provided by van der Waals interactions—involving the molecules.
