This concept applies equally in one, two, and 3-dimensional spaces. The entire crystal lattice is usually produced by frequently reproducing the sample on the device cell in all directions.
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
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。
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
Crystalline construction is characterized by a geometrical, repeating pattern of symmetric molecular construction. The arrangement of atoms varieties these ordered, repeating patterns.
Encyclopaedia Britannica's editors oversee matter spots wherein they may have extensive information, whether or not from several years of practical experience received by working on that written content or by using research for a complicated diploma. They produce new material and verify and edit information received from contributors.
解理：无解理。所谓解理是指矿物被打击时，沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类：极完全解理、完全解理、中等解理、不完全解理和无解理，水晶属于无解理。
Crystals could be developed beneath moderate conditions from all ninety two By natural means happening things except helium, and helium could be crystallized at very low temperatures by making use of twenty five atmospheres of tension.
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：
广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。
The fundamental models of solids are possibly atoms or atoms which have blended into molecules. The electrons of an atom transfer in orbits that form a shell framework within the nucleus. The shells are stuffed in a systematic buy, with each shell accommodating only a small number of electrons. Different atoms have distinctive figures of electrons, which can be dispersed inside a characteristic electronic framework of crammed and partly crammed shells.
There are actually other minerals and molecules which will sort these crystal lattices. Snowflakes certainly are a traditional example of a about symmetric and geometrically patterned construction from ice crystals, and gemstones of all kinds are generally crystals.
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
The C60 molecules, also known as buckyballs, are fairly sturdy and Pretty much incompressible. Crystals are shaped this kind of the balls are organized within an fcc lattice having a one-nanometre spacing concerning the centres of adjacent balls. The equivalent C70 molecule has The form of a rugby ball; here C70 molecules also kind an fcc crystal when stacked jointly. The solid fullerenes type molecular crystals, with weak binding—provided by van der Waals interactions—concerning the molecules.
