Crystals are attractive rock formations which have amazed people for thousands of yrs. They may be utilized for numerous different things, not only for decoration. A lot of the to start with radios ever invented made use of crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Exclusive Qualities and harmonic abilities of crystals to help make hugely exact measurements and adjustments.
10This is the silicon chip—just a little chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
Fig. three: A library of lattice symmetries is often accessed by shifting the particle core and DNA shell.
25If you're a Billy Crystal fan, you will appreciate this movie.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》
Lattices may have just one lattice point for every mobile or more than one, yielding a complete of fourteen Bravais crystal lattice styles. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the three-dimensional array created by a list of discrete factors.
Crystals look exceptional from many other rocks and minerals, but �?barring a number of Distinctive conditions �?nearly all minerals hide a crystalline construction beneath the area.
You will find there's identical website directive about crystal glass which differentiates concerning complete direct crystal, lead crystal and crystal.
13Nearly all pcs consist of a quartz-crystal clock to manage 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。
Solids that have small-variety order but absence very long-vary purchase are known as amorphous. Practically any materials might be made amorphous by immediate solidification in the melt (molten state). This situation is unstable, and also the sound will crystallize in time. If your timescale for crystallization is decades, then the amorphous condition appears secure.
15The trick to a very good thermoelectric content is a crystal construction where electrons can flow 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。
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（development strains）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”
This crystal construction is to blame for the unique Bodily and chemical Qualities of sodium chloride, including its significant melting level, electrical conductivity, and talent to variety ionic bonds very easily.
