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 stunning rock formations that have astonished humans for Many years. They may be used for lots of different things, not only for decoration. A lot of the initially radios ever invented employed crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Specific Attributes and harmonic abilities of crystals to generate really precise measurements and changes.
10This is the silicon chip—a little bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
Incorporate to phrase listing Insert to phrase list C2 [ U ] clear glass of really high-quality, typically with its surface cut into delicate styles
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
Lattices may have one lattice level for each cell or more than one, yielding a total of 14 Bravais crystal lattice styles. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the a few-dimensional array made by a set of discrete details.
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。
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。
Q.four. What is the distinction between atomic construction and crystal structure? Ans. The primary distinction between atomic construction and crystal composition lies of their definitions: atomic framework refers to how atoms are organized within a one molecule or maybe a cluster of molecules, whereas crystal construction worries the precise arrangement of atoms inside of a sound compound.
颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。
看孔眼：对于缀穿水晶制品（如项链、手链、佛珠），要看孔眼是否平直，孔的粗细是否均匀，有无细小裂纹。孔壁必须清澈透明，无“白痕”。
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。
Crystals are categorized in general categories, for instance insulators, metals, semiconductors, and molecular solids. One crystal of the insulator is frequently transparent and resembles a piece of glass. Metals are shiny Unless of course they have rusted. Semiconductors are sometimes shiny and often clear but are hardly ever rusty. Many crystals can be classified as just one type of sound, while some have intermediate conduct. Cadmium sulfide (CdS) may be prepared in pure type and is an excellent insulator; when impurities are included to cadmium sulfide, it becomes a fascinating semiconductor.
crystal Alteration is variable: absent in several crystals, in Other individuals producing dense sericite aggregates which may demonstrate some recrystallization results to create coarser-grained white mica. From the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are occasionally arranged in aggregates. From your Cambridge English Corpus In addition, haloarchaeal cells have been embedded within salt crystals beneath laboratory problems and subsequently analysed by gentle microscopy. Within the Cambridge English Corpus The white clouds (commonly sparse) ended up also widely regarded as remaining composed of tiny crystals of drinking water ice, rather like cirrus in our get more info ambiance. In the Cambridge English Corpus They can be found in evaporite salt lakes and will be trapped in salt crystals for the duration of evaporation. From your Cambridge English Corpus For that reason, the cells (organelles and membranes) are destroyed mechanically by ice crystals, bringing about Demise as a result of cell lysis. With the Cambridge English Corpus The crystals were Employed in the main or next orders of reflection. With the Cambridge English Corpus Within our 8xperiments, the crystals have been cubes having a foundation space of eight e mm. In the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and pressure.
