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 that have stunned humans for Many several years. They may be utilized for a lot of various things, not just for decoration. Many of the first radios ever invented made use of crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Exclusive Houses and harmonic capabilities of crystals to help make really exact measurements and changes.

对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正，浓度较高，内部无瑕为好。种类上紫晶最贵，其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。

Large crystals of diamond are valuable gemstones. The crystal has other interesting Houses; it's got the best sound velocity of any reliable and is the best conductor of heat. In addition to diamond, another frequent sort of carbon is graphite, and that is a layered material. Each and every carbon atom has a few coplanar around neighbours, forming an arrangement called the honeycomb lattice. 3-dimensional graphite crystals are received by stacking identical layers.

25If you are a Billy Crystal admirer, you are going to love this film.如果你是比利·克里斯特尔的影迷，你就会喜欢这部电影。《柯林斯英汉双解大词典》

Monoclinic �?Characterized by three unequal axes, two of which intersect at an oblique angle, whilst the third is perpendicular on the aircraft of one other two.

⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果

The weather are identified in a variety of crystal packing arrangements. The most common lattice structures for metals are Those people acquired by stacking the atomic spheres into quite possibly the most compact arrangement.

水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：

. The next layer is shaded within the figure. It's the exact same airplane-triangular composition; the atoms sit while in the holes shaped by the main layer. The primary layer has two equal sets of holes, though the atoms of the second layer can occupy only one established. The third layer, labeled C

Crystal Lattices There are 7 techniques of crystal structures, that are also called lattices or Place lattices:

⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。

Binary crystals are found in numerous buildings. Some pairs of factors variety multiple composition. At home temperature, cadmium sulfide may possibly crystallize either during the zinc blende or wurtzite construction. Alumina also has two possible structures at room temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit various structures at diverse temperatures. Among the many check here most intricate crystals are People of silicon dioxide (SiO2), which has 7 diverse constructions at numerous temperatures and pressures; the most common of these buildings is quartz.
