17These rings are indicative in the crystal construction of nickel and might be discussed only by invoking wavelike Attributes of sunshine.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
the sound condition of many very simple substances, that have a regular condition and surfaces organized in similar styles
Chemical Bonds The kinds of chemical bonds fashioned amongst atoms or groups of atoms in crystals rely upon their dimension and electronegativity. You'll find four categories of crystals as grouped by their bonding:
The ordered internal composition of large crystals, much like the fluorite and quartz shown right here, is mirrored within their geometric shapes.
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。

水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见，所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人，所以通常人们会要求水晶净度越高越好，尽量避免有较明显的内含物的水晶。
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。
24I want to make my indicating crystal apparent.我想把我的意思解释得清清楚楚。《牛津词典》
⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。
用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
国家还并未给天然水晶提供一个等级划分的具体标准，水晶品种繁杂，每一品种都有他不同的评判标准。
This Evaluation chronicles above twenty years of study into creating a genetic code for crystal engineering. Rather then directing biological processes, this code makes use of artificial sorts of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which just about each individual facet of the resultant constructions could be systematically managed. Within just this conceptual framework, the structural and practical advances are described in order to define the current volume of sophistication and also to predict foreseeable future directions in the platform.
