天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。

①压电效�?在机械力(压力或拉�?作用下，水晶单晶体的两端会产生电荷，其电量相等但符号相反。在工业上，无色、无缺陷、不具双晶的水晶常被用来作压电石英片。

A crystal composition concentrates on how the atoms are arranged inside the crystal. On the other hand, crystallographers have an interest in the overall form and size in the crystal in addition to its exterior qualities. To accomplish this, they should understand about the crystal system.

If you would like see how crystals are formed, you'll be able to do some venture inside your incredibly very own kitchen and find out the formation from the crystals occur with all your possess eyes . This can be carried out by Placing a little degree of table salt into some regular faucet h2o, hold out 24 several hours, and you may see pleasant cubed formations. This occurs since the drinking water is evaporating, which causes the atoms which make up the salt (the mineral) along with the water to return nearer collectively.

水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。

结晶�?When sea drinking water is permitted to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。

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。

The weather are identified in a variety of crystal packing arrangements. The most typical lattice structures for metals are These acquired by stacking the atomic spheres into essentially the most compact arrangement.

crystal The recently crystallized quartz grains are characterized by elongate crystals oriented oblique on the shear band margins, defining a normal grain-shape foliation. 来自 Cambridge English Corpus We are saying the chain topology within the high w region functions given that the proverbial ' scratch-on-theglass ' essential within the natural chemistry laboratory to make crystals. 来自 Cambridge English Corpus The age scatter between the individual website crystals may possibly replicate incorporation of xenocrysts from before 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.

In the Cambridge English Corpus We say the chain topology within the substantial w location acts because the proverbial ' scratch-on-theglass ' needed during the organic and natural chemistry laboratory to help make crystals. Through the Cambridge English Corpus Continuous-pressure and temperature molecular-dynamics simulations of crystals of your lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. Through the Cambridge English Corpus Along with these, dust particles have been observed in minimal-temperature plasmas, like All those used in plasma processing and plasma crystals. Through the Cambridge English Corpus The ultimate Portion of the e-book concentrates on peculiarities of strongly coupled dusty plasmas, like the formation of dust crystals and connected interesting forces. From your Cambridge English Corpus Finish characterization of injury threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. In the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or even more irregular, Most important morphologies weren't observed. Through the Cambridge English Corpus See all samples of crystal These illustrations are from corpora and from resources on the internet. Any views from the examples don't characterize the feeling of your Cambridge Dictionary editors or of Cambridge College Push or its licensors.

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（development 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」。

对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
