17These rings are indicative in the crystal construction of nickel and may be spelled out only by invoking wavelike properties 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。
Bismuth (Bi) seems to get a metallic, but the volume of electrons readily available for electrical conduction is comparable to that of semiconductors. In reality, bismuth is named a semimetal. Molecular solids usually are crystals formed from molecules or polymers. They are often insulating, semiconducting, or metallic, based on the type of molecules from the crystal. New molecules are consistently currently being synthesized, and lots of are created into crystals. The number of unique crystals is big.
These improvements contain exotic structures with programmable lattice symmetries and effectively-described crystal routines, responsive elements that leverage the intrinsic properties of nucleic acids to govern structures on desire, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals offering insights into light-weight–subject interactions. Looking forward, we obstacle the read more Group to leverage the extraordinary structural Management afforded by crystal engineering with DNA to synthesize lessons of purposeful products that drive outside of what has become possible with Obviously transpiring crystalline supplies or All those created by much more conventional approaches.
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
25If you are a Billy Crystal fan, you may appreciate this film.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》
当二氧化硅结晶完美时就是水晶；结晶不完美的就是石英：二氧化硅胶化脱水后就是玛瑙；二氧化硅含水的胶体凝固后就成为蛋白石；二氧化硅晶粒小于几微米时，就组成玉髓、燧石、次生石英岩。
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。
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。

颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。
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。
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。
在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
