Not all crystals are Similarly crystalline. There are frequently impurities, and the ionic & covalent among molecules can create vastly diverse buildings outside of a similar content. A fantastic example of this are diamonds and graphene.

23Sometimes, even so, the crystal form of the silicate inclusions is noticed to resemble extra closely The inner composition of diamond than that of other silicate minerals.然而,有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。

发晶的价值取决于发的颜色、罕见性及大小,一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态,便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值,通过它们可了解几百万年前地球上水的成分及变化。

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�?”

25If you're a Billy Crystal lover, you can expect to love this movie.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 may have a person lattice level for every cell or multiple, yielding a total of fourteen Bravais crystal lattice sorts. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the a few-dimensional array produced by a set of discrete points.

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。

Like a very hot Remedy cools or a saturated Alternative evaporates, particles draw shut plenty of for chemical bonds to type. Crystals might also kind from deposition directly from the fuel stage. Liquid crystals possess particles oriented in an structured fashion, like strong crystals, nevertheless have the ability to movement.

13Nearly all computer systems consist of a quartz-crystal clock to regulate their Procedure.几乎所有的计算机都有一个石英晶体时钟来调节它们的运行。

晶体 Silicon crystals developed inside a laboratory convert mild into electrical Electrical power. 在实验室中长成的硅晶体可将光线转变为电能。

地质学家目前为止对晶洞形成还没有广泛认同的理论,但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴,甚至动物挖的地洞。经过漫长时间,空腔的外壁变硬,溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间,缓慢渗入的矿物使得晶体在空腔内部结晶。

Orthorhombic: They are rhombic prisms and dipyramids that resemble tetragons but without sq. cross-sections.

14For case in point, We have now Quartz crystal clocks and watches exact to within just 1 read more moment a year.例如,我们使用的每年误差不超过1分钟的石英水晶钟表和手表。

21You all know the way if you take a crystal prism and go a beam of daylight through it, you obtain a spectrum, which looks like a constant band of rainbow colors.
