27Local economists have appeared into their crystal balls and viewed one thing somewhat awful.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》
Crystals are beautiful rock formations that have shocked people for thousands of several years. They may be useful for quite a few different things, not just for decoration. Lots of the very first radios at any time invented utilised crystals to transmit the radio waves. Some instruments, like quartz watches and laser crystals, use special Houses and harmonic abilities of crystals to produce highly precise measurements and adjustments.
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�?”
看抛光：抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。
They are going to inevitably create a wonderful small uniform cluster of atoms, this is the process of expanding crystals. The more they will come collectively, the greater of a development is going to be noticeable on the naked eye. Researchers can ascertain what mineral they are looking at by how the crystals type.
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。
Amongst the binary crystals, the best buildings to visualize are Those people with equal figures of the two forms of atoms. The composition of sodium chloride is predicated over a cube. To construct the lattice, the sodium and chlorine atoms are placed on alternate corners of a cube, along with the framework is repeated (Determine 3B).
The definition of a reliable appears apparent; a solid is normally regarded as currently being difficult and company. On inspection, nonetheless, the definition results in being a lot less straightforward. A cube of butter, such as, is hard just after staying saved in a very fridge and is Evidently a good. Just after remaining to the kitchen area counter for a day, the same cube will become rather comfortable, and it is unclear In the event the butter need to nonetheless be regarded a stable.
There are two such doable periodic arrangements. In each, the primary layer has the atoms packed into a plane-triangular lattice in which each and every atom click here has 6 speedy neighbours. Determine 2 displays this arrangement for the atoms labeled A
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（advancement 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」。
⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。
