17These rings are indicative in the crystal structure of nickel and will be discussed only by invoking wavelike properties of light.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
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。
景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。
第一种是“全包裹体”，在水晶结晶的时候把这些物质包裹在晶体里面，这类包裹体所形成的各种景象，大多保持了水晶结晶时的原状，也就是说保存了几亿年的原状，极少受到自然环境的影响。
25If you are a Billy Crystal admirer, you may 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》
Lattices can have one particular lattice stage for each mobile or more than one, yielding a total of 14 Bravais crystal lattice kinds. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the three-dimensional array made by a set of discrete points.
⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果
发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。
Metallic Crystals: Metals often kind metallic crystals, wherever a few of the valence electrons are absolutely free to move all over the lattice. Iron, for example, can sort diverse metallic crystals.
crystal The newly crystallized quartz grains are characterised by elongate crystals oriented oblique on the shear band margins, defining a standard grain-form foliation. 来自 Cambridge English Corpus We say the chain topology in the superior w area acts given that the proverbial ' scratch-on-theglass ' wanted from the natural and organic chemistry laboratory to help make crystals. 来自 Cambridge English Corpus The age scatter amongst the person crystals may mirror incorporation of xenocrysts from before magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene types neutral to pale brown, subhedral to anhedral crystals, sometimes made up of inclusions of plagioclase microlaths and opaque phases.
用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
国家还并未给天然水晶提供一个等级划分的具体标准，水晶品种繁杂，每一品种都有他不同的评判标准。
Crystals are categorized on the whole classes, like insulators, metals, semiconductors, and molecular solids. Just one crystal of the insulator is often transparent and resembles a piece of glass. Metals are shiny Except if they've rusted. Semiconductors are occasionally shiny and from time to time clear but are in no way rusty. A lot of crystals could be categorised as only one style of solid, while others have intermediate conduct. Cadmium sulfide (CdS) can be organized in pure variety and is a superb insulator; when impurities are added to cadmium sulfide, it turns into a fascinating semiconductor.
crystal Alteration is variable: absent in lots of crystals, in others producing dense sericite aggregates which can clearly show some recrystallization consequences to supply coarser-grained white mica. Through the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are sometimes arranged in aggregates. In the Cambridge English Corpus In addition, haloarchaeal cells had been embedded inside salt crystals beneath laboratory problems and subsequently analysed by mild microscopy. From your Cambridge English Corpus The white clouds (usually sparse) ended up also greatly regarded as remaining composed of little crystals of water ice, alternatively like cirrus within our atmosphere. Within the Cambridge English Corpus They can be located in evaporite salt lakes and might be trapped in salt crystals throughout evaporation. Through the Cambridge English Corpus Consequently, the cells (organelles and membranes) are wrecked mechanically by ice crystals, resulting in death as a result of cell lysis. From your Cambridge click here English Corpus The crystals had been Employed in the first or 2nd orders of reflection. Within the Cambridge English Corpus Within our 8xperiments, the crystals were being cubes with a base spot of eight e mm. Within the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and pressure.
