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：
⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。
4Without a crystal ball, It truly is unachievable to convey in which we are going to be following 12 months.不用水晶球预卜未来，我们说不准明年处境如何呀。《牛津词典》
Fig. seven: A template-directed strategy can Command The position of developing blocks on a area from the formation of sophisticated structures.
Additionally, there are a lot of products that resemble crystals but are literally polycrystals. Polycrystals type when microscopic crystals fuse together to sort a solid. These elements do not consist of requested lattices.
These examples are from corpora and from resources on the web. Any viewpoints during the illustrations tend not to represent the feeling on the Cambridge Dictionary editors or of Cambridge College Press or its licensors.
解理：无解理。所谓解理是指矿物被打击时，沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类：极完全解理、完全解理、中等解理、不完全解理和无解理，水晶属于无解理。
For a incredibly hot Option cools or simply a saturated Alternative evaporates, particles draw close ample for chemical bonds to type. Crystals could also sort from deposition straight from the fuel phase. Liquid crystals have particles oriented in an organized method, like sound crystals, however can move.
Crystals are sometimes seen as a little something of enormous attractiveness, and they are commonly utilised with diamonds or other stones to make items of jewellery. Nearly all of crystals now are person-produced in laboratories.
crystal The freshly crystallized quartz grains are characterised by elongate crystals oriented oblique to your shear band margins, defining an average grain-condition foliation. 来自 Cambridge English Corpus We say the chain topology while in the superior w region acts given that the proverbial ' scratch-on-theglass ' wanted within the organic and natural chemistry laboratory for making crystals. 来自 Cambridge English Corpus The age scatter amongst the person crystals may well mirror incorporation of xenocrysts from before magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, sometimes made up of inclusions of plagioclase microlaths and opaque phases.
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。
The arrangement of the atom’s electrons decides its chemical Houses. The here properties of solids tend to be predictable with the Attributes of their constituent atoms and molecules, and the various shell constructions of atoms are thus chargeable for the variety of solids.
14For example, We've got Quartz crystal clocks and watches correct to in one particular moment a calendar year.例如，我们使用的每年误差不超过one分钟的石英水晶钟表和手表。
A different form of crystalline carbon is predicated with a molecule with sixty carbon atoms named buckminsterfullerene (C60). The molecular form is spherical. Each and every carbon is bonded to three neighbours, as in graphite, plus the spherical condition is reached by a mix of 12 rings with 5 sides and twenty rings with six sides. Similar buildings ended up 1st visualized through the American architect R. Buckminster Fuller for geodesic domes.
