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：
the solid condition of numerous very simple substances, that have a daily condition and surfaces organized in identical patterns
对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正，浓度较高，内部无瑕为好。种类上紫晶最贵，其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。

结晶�?When sea drinking water is permitted to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。
时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：
损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。
水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。
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。
Within the Cambridge English Corpus We are saying the chain topology within the substantial w location functions since the proverbial ' scratch-on-theglass ' necessary in the natural chemistry laboratory to help make crystals. In the Cambridge English Corpus Consistent-tension and temperature molecular-dynamics simulations of crystals with the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. From the Cambridge English Corpus Along with these, dust particles have been noticed in lower-temperature plasmas, like These used in plasma processing and plasma crystals. Through the Cambridge English Corpus The ultimate part of the guide focuses on peculiarities of strongly coupled dusty plasmas, like the development of dust crystals and affiliated desirable forces. From your Cambridge English Corpus Entire characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. Within the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or more irregular, Major morphologies weren't observed. In the Cambridge English Corpus See all examples of crystal These illustrations are from corpora and from sources on the internet. Any views while in the illustrations will not depict the viewpoint with the Cambridge Dictionary editors or of Cambridge College Press or its licensors.
There are actually only some various device-mobile styles, so a number of crystals share an individual unit-cell kind. An important characteristic of the unit cell is the number of atoms it includes. The full number of atoms in all the crystal may be the amount in each cell multiplied by the volume of unit cells. Copper and aluminum read more (Al) Every single have a single atom for every device cell, when zinc (Zn) and sodium chloride have two. Most crystals have only some atoms per unit cell, but there are a few exceptions. Crystals of polymers, one example is, have A large number of atoms in each unit cell.
压电性：水晶晶体受到压力时会产生电荷；反之，受到电压作用时，晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能，称压电性。
This crystal framework is answerable for the exceptional Actual physical and chemical Qualities of sodium chloride, including its higher melting place, electrical conductivity, and skill to type ionic bonds quickly.
