27Local economists have seemed into their crystal balls and viewed a thing relatively terrible.当地的经济学者们已预测到将会出现棘手的问题。《柯林斯英汉双解大词典》
③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。
一般而言，紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅，颜色较深的为A级，稍浅的为B级。一般颜色较深的价格高，但要以不深暗为标准。颜色包括两种，一种是水晶本身的颜色，另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正，分布要均匀，不能太深或太浅，如澳州玉、蓝玉髓、紫晶、黄水晶，其价格就高。无色的水晶内含包裹体的颜色艳丽，其价格也高，如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。
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�?”
You can also find numerous materials that resemble crystals but are literally polycrystals. Polycrystals sort when microscopic crystals fuse collectively to form a strong. These products usually do not include purchased lattices.
发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。
Crystals is often grown underneath reasonable conditions from all ninety two By natural means occurring features except helium, and helium is usually crystallized at very low temperatures by using twenty five atmospheres of tension.
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。

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。
The arrangement of an atom’s electrons establishes its chemical Houses. The properties of solids are usually predictable with the Qualities in their constituent atoms and molecules, and the various shell buildings of atoms are thus liable for the variety of solids.
玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
crystal Alteration is variable: absent in many crystals, in Other people generating dense sericite aggregates which may show some recrystallization results to create coarser-grained white mica. Through the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are occasionally organized in aggregates. From the Cambridge English Corpus Furthermore, haloarchaeal cells were being embedded in just salt crystals underneath laboratory disorders and subsequently analysed by gentle microscopy. With the Cambridge English Corpus The white clouds (normally sparse) were being also greatly viewed as being composed of little crystals of drinking water ice, fairly like cirrus inside our environment. With the Cambridge English Corpus They may be located in evaporite salt lakes and can be trapped in salt crystals for the duration of evaporation. From the Cambridge English Corpus Consequently, the cells (organelles and click here membranes) are wrecked mechanically by ice crystals, resulting in death by way of cell lysis. From the Cambridge English Corpus The crystals had been used in the 1st or second orders of reflection. In the Cambridge English Corpus In our 8xperiments, the crystals had been cubes by using a foundation region of 8 e mm. Through the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and pressure.
