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：
A different entertaining, and delicious, experiment will be to form significant crystals applying sugar. By heating sugar with drinking water after which allowing this Option evaporate on sticks, you'll be able to kind rock sweet from sugar crystals!
A fundamental strategy in crystal constructions would be the device mobile. It's the smallest device of volume that permits equivalent cells being stacked jointly to fill all Place. By repeating the pattern from the device cell time and again in all Instructions, your complete crystal lattice may be built. A dice is The best example of a unit cell. Two other illustrations are shown in Figure one. The 1st would be the unit mobile for a confront-centred cubic lattice, and the second is for any overall body-centred cubic lattice. These constructions are explained in the following paragraphs.
Tetragonal: These crystals form prisms and double pyramids. The framework is sort of a cubic crystal, apart from 1 axis is for a longer period than the other.
You will discover a variety of crystals depending on geometric constructions, crystal progress, and substance. There may be arrangements of hexagonal carbon atoms or amethyst that makes hexagonal pyramid constructions.
⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
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
Crystals are almost nothing in excess of an requested arrangement of molecules or atoms. Crystals are available in many alternative sizes and styles, and each one has unique attributes. What they are created of establishes how it's going to kind.
13Nearly all computers contain a quartz-crystal clock to control their operation.几乎所有的计算机都有一个石英晶体时钟来调节它们的运行。
晶体 Silicon crystals grown in the laboratory convert gentle into electrical Vitality. 在实验室中长成的硅晶体可将光线转变为电能。
say cheese something which someone that is using a photograph of you tells you to say so get more info that your mouth would make the shape of the smile
There are actually other minerals and molecules that can sort these crystal lattices. Snowflakes absolutely are a traditional example of a roughly symmetric and geometrically patterned structure from ice crystals, and gemstones of all varieties are generally crystals.
水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟，喜欢将它们摆在家里或办公室里，认为水晶球有灵性，能保平安，带来财运。不过天然水晶不像看起来那么晶莹剔透，它也有瑕疵，我们在选购饰品的时候要注意。此外，我们还要掌握水晶的评价依据、选购方法，这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
