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 further exciting, and delicious, experiment is to type large crystals employing sugar. By heating sugar with drinking water after which allowing this Resolution evaporate on sticks, you could form rock sweet from sugar crystals!
10This is definitely the silicon chip—just a little chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
Most sound components found in character exist in polycrystalline kind as an alternative to as a single crystal. They are literally composed of millions of grains (tiny crystals) packed with each other to fill all House. Every single person grain has a distinct orientation than its neighbours. Although very long-variety buy exists in just a single grain, with the boundary between grains, the ordering changes course. A standard bit of iron or copper (Cu) is polycrystalline.
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。
第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。
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�?
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。
One of the binary crystals, the easiest constructions to visualise are People with equal figures of the two kinds of atoms. The composition of sodium chloride is predicated over a dice. To build the lattice, the sodium and chlorine atoms are put on alternate corners of the dice, and also the composition is repeated (Figure 3B).
22Working from what The us by now appreciates about by itself, the bureau's industry experts as well as other demographers present an irresistible, if clouded, crystal ball between their visions.
15The trick to a very good thermoelectric material is often a crystal composition in which electrons can movement 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。
Crystal Lattices There are 7 devices of crystal constructions, which can be also called lattices or space lattices:
Crystals are categorised on the read more whole categories, for example insulators, metals, semiconductors, and molecular solids. Only one crystal of the insulator is generally transparent and resembles a bit of glass. Metals are shiny Except they've got rusted. Semiconductors are occasionally shiny and in some cases clear but are never rusty. Many crystals could be classified as just one kind of strong, while some have intermediate conduct. Cadmium sulfide (CdS) is often prepared in pure sort and is a wonderful insulator; when impurities are additional to cadmium sulfide, it gets to be an interesting semiconductor.
