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：
An additional fun, and delicious, experiment is always to kind significant crystals using sugar. By heating sugar with water after which allowing this Remedy evaporate on sticks, you'll be able to type rock sweet from sugar crystals!
A crystal construction concentrates on how the atoms are organized In the crystal. On the other hand, crystallographers have an interest in the overall shape and sizing on the crystal and also its external attributes. To accomplish this, they need to understand about the crystal program.
Big crystals of diamond are useful gemstones. The crystal has other appealing properties; it has the very best audio velocity of any solid and is the best conductor of warmth. Apart from diamond, one other frequent kind of carbon is graphite, and that is a layered product. Every carbon atom has 3 coplanar in close proximity to neighbours, forming an arrangement known as the honeycomb lattice. 3-dimensional graphite crystals are obtained by stacking identical levels.
C2 [ U ] transparent glass of very superior quality, ordinarily with its surface area Lower into fragile designs:
Lattices may have a person lattice point for each mobile or multiple, yielding a total of 14 Bravais crystal lattice sorts. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the a few-dimensional array made by a list of discrete details.
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
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。
In the meantime, to be sure ongoing aid, we've been exhibiting the location without having variations and JavaScript.
22Working from what The united states by now knows about alone, the bureau's specialists as well as other demographers offer an irresistible, if clouded, crystal ball among the their visions.
15The trick to a great thermoelectric product is usually a crystal construction during which electrons can stream freely.制造一种好的热电材料的关键是，需要一种电子可以自由流动的晶体结构。
There are other minerals and molecules that will kind these crystal lattices. Snowflakes absolutely are a common example of a approximately symmetric and geometrically patterned composition from ice more info crystals, and gemstones of all kinds are typically crystals.
Crystals are categorized generally classes, for instance insulators, metals, semiconductors, and molecular solids. Only one crystal of an insulator will likely be clear and resembles a bit of glass. Metals are shiny unless they've got rusted. Semiconductors are occasionally shiny and at times clear but are by no means rusty. Quite a few crystals can be labeled as an individual type of strong, while some have intermediate conduct. Cadmium sulfide (CdS) is often prepared in pure kind and is an excellent insulator; when impurities are included to cadmium sulfide, it becomes an interesting semiconductor.
⑥白色的包裹体有蚀变的绿泥石、云母、愈合裂隙、水晶、方解石、透闪石等。
