4Without a crystal ball, It is not possible to mention where we'll be next yr.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》
Most reliable supplies found in nature exist in polycrystalline kind in lieu of as just one crystal. They are literally composed of an incredible number of grains (compact crystals) packed together to fill all space. Each personal grain has a distinct orientation than its neighbours. Although long-assortment purchase exists in just one particular grain, within the boundary among grains, the purchasing alterations path. A normal bit of iron or copper (Cu) is polycrystalline.
Fig. 4: Building blocks with various shapes and floor chemistries immediate the formation of unique crystal symmetries.
Monoclinic �?Characterised by three unequal axes, two of which intersect at an oblique angle, while the 3rd is perpendicular to the aircraft of one other two.
对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。
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。
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。
crystal The freshly crystallized quartz grains are characterized by elongate crystals oriented oblique into the shear band margins, defining an average grain-form foliation. 来自 Cambridge English Corpus We say the chain topology in the large w area acts because the proverbial ' scratch-on-theglass ' needed within the natural chemistry laboratory for making crystals. 来自 Cambridge English Corpus The age scatter among the person crystals may mirror incorporation of xenocrysts from previously magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene varieties neutral to pale brown, subhedral to anhedral crystals, from time to time containing inclusions of plagioclase microlaths and opaque phases.

Crystals are not merely renowned for his or her physical physical appearance, but diverse crystals of different components and formations can lead to an enormous selection of works by using and physical Qualities.
Crystals are categorized in general classes, including insulators, metals, semiconductors, and molecular solids. One crystal of an insulator is generally clear and resembles a piece of glass. Metals are shiny Unless of course they have rusted. Semiconductors are occasionally shiny and often clear but are hardly ever here rusty. Quite a few crystals might be categorised as a single type of strong, while others have intermediate conduct. Cadmium sulfide (CdS) can be ready in pure form and is a wonderful insulator; when impurities are additional to cadmium sulfide, it gets to be a fascinating semiconductor.
矿物成分：针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶，如发晶、钛晶、绿幽灵等，发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶；含铁�?；呈金黄色或柠檬�?)称黄水晶；含锰和钛呈玫瑰色者称蔷薇石英，即粉水晶；烟色者称烟水晶；褐色者称茶晶；黑色透明者称为墨晶。
