This idea applies Similarly in one, two, and a few-dimensional spaces. The entire crystal lattice might be constructed by regularly reproducing the sample in the unit cell in all directions.
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 can be not possible to say where by we will be next calendar year.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》
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。
You will find there's similar directive about crystal glass which differentiates amongst total guide crystal, direct crystal and crystal.
Meanwhile, to be sure ongoing assistance, we're displaying the site devoid of types and JavaScript.
22Working from what The united states currently is aware about by itself, the bureau's specialists and various demographers offer you an irresistible, if clouded, crystal ball amongst their visions.
⑥、丝印：水晶表面附有不同的色料进行效果处理，颜色层面较厚，着力后方可脱落。
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（progress traces）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
The structure of your sodium atoms by itself, or the chlorine atoms by itself, is fcc and defines the device mobile. The sodium chloride construction Hence is built up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) is predicated about the bcc construction; each and every other atom is cesium or chlorine. In this instance, the device cell is really a dice. The read more 3rd significant composition for AB
crystal Alteration is variable: absent in many crystals, in Other folks producing dense sericite aggregates which may present some recrystallization effects to supply coarser-grained white mica. From your Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes organized in aggregates. From the Cambridge English Corpus In addition, haloarchaeal cells ended up embedded within just salt crystals underneath laboratory ailments and subsequently analysed by light microscopy. Through the Cambridge English Corpus The white clouds (commonly sparse) had been also greatly regarded as staying composed of tiny crystals of h2o ice, somewhat like cirrus inside our ambiance. From your Cambridge English Corpus They're located in evaporite salt lakes and might be trapped in salt crystals in the course of evaporation. Within the Cambridge English Corpus As a result, the cells (organelles and membranes) are destroyed mechanically by ice crystals, bringing about death through cell lysis. In the Cambridge English Corpus The crystals were Employed in the primary or 2nd orders of reflection. From your Cambridge English Corpus Inside our 8xperiments, the crystals were cubes having a base place of eight e mm. From the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : effect of temperature and tension.
