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 different exciting, and delicious, experiment will be to variety large crystals applying sugar. By heating sugar with h2o and then allowing this Option evaporate on sticks, you may sort rock candy from sugar crystals!
看做工：水晶制品加工过程分为两种，即磨工和雕工。如水晶项链、手链、耳环等属于研磨品；观音像、内画鼻烟壶等属于雕刻品。
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
25If you're a Billy Crystal admirer, you can like this film.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》
Not all crystals form in drinking water, but nearly all crystals form the exact same way, atoms occur collectively and turn into a uniformed cluster. The procedure can take as very little as a few days to possibly a thousand decades. Organic crystals that originate from the Earth variety the same way.
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：
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。
Among the binary crystals, the easiest structures to visualise are Those people with equal quantities of The 2 varieties of atoms. The composition of sodium chloride is based over a cube. To build the lattice, the sodium and chlorine atoms are put on alternate corners of a dice, as well as structure is repeated (Determine 3B).
晶体 Silicon crystals developed in a very laboratory convert light-weight into electrical Electrical power. 在实验室中长成的硅晶体可将光线转变为电能。
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
Crystallography is definitely the examine of crystals, and it deals with all the things from fantastic geometric styles to seemingly random conglomerations of particles and minerals.
The construction with the sodium atoms by yourself, or even the chlorine atoms alone, is fcc and defines the unit cell. The sodium chloride structure So is designed up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) is based within the bcc construction; each and every other atom is cesium or chlorine. In cases like this, the device mobile can be a cube. The third significant structure for AB
crystal Alteration is variable: absent in several crystals, in Many others making dense sericite aggregates which may present some recrystallization outcomes to generate coarser-grained white mica. Within the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are sometimes organized in aggregates. Within the Cambridge English Corpus Moreover, haloarchaeal cells ended click here up embedded in salt crystals below laboratory conditions and subsequently analysed by light-weight microscopy. With the Cambridge English Corpus The white clouds (usually sparse) have been also broadly considered becoming composed of small crystals of h2o ice, instead like cirrus in our ambiance. In the Cambridge English Corpus They are present in evaporite salt lakes and can be trapped in salt crystals throughout evaporation. Within the Cambridge English Corpus As a result, the cells (organelles and membranes) are ruined mechanically by ice crystals, leading to death by means of mobile lysis. From your Cambridge English Corpus The crystals had been Employed in the main or second orders of reflection. In the Cambridge English Corpus Inside our 8xperiments, the crystals ended up cubes having a foundation location of eight e mm. From the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and pressure.
