诗中“胜美玉”，“过冰清”，写出水晶的质地美，而“亦欲应时明”则描绘出水晶充满灵性的动态美，耐人寻味。罗维是有独特眼光，懂得水晶真谛，第一个称赞水晶超过美玉的伟大诗人。他的认识已被千年之后的科学理论所证实；以水晶为直接吟咏对象的诗篇还有：
Crystals are gorgeous rock formations which have shocked individuals for A huge number of many years. These are used for several various things, not just for decoration. Most of the first radios ever invented utilized crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Distinctive properties and harmonic capabilities of crystals to help make extremely precise measurements and changes.
A fundamental thought in crystal buildings could be the unit cell. It is the smallest device of volume that permits similar cells to generally be stacked jointly to fill all Area. By repeating the pattern with the unit cell over and over in all directions, the entire crystal lattice might be constructed. A dice is The best example of a device mobile. Two other illustrations are demonstrated in Determine one. The first is the unit cell for your experience-centred cubic lattice, and the next is for the physique-centred cubic lattice. These structures are discussed in the following paragraphs.
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
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。
水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见，所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人，所以通常人们会要求水晶净度越高越好，尽量避免有较明显的内含物的水晶。

Metallic Crystals: Metals normally type metallic crystals, in which a number of the valence electrons are free of charge to move through the entire lattice. Iron, as an example, can form various metallic crystals.

Crystal Lattices You will find seven methods of crystal buildings, which can get more info be also called lattices or Area lattices:
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。
An additional form of crystalline carbon is based on the molecule with 60 carbon atoms known as buckminsterfullerene (C60). The molecular shape is spherical. Every single carbon is bonded to a few neighbours, as in graphite, and the spherical condition is realized by a mix of 12 rings with 5 sides and 20 rings with six sides. Equivalent buildings ended up initially visualized through the American architect R. Buckminster Fuller for geodesic domes.
