This concept applies equally in a single, two, and a few-dimensional spaces. Your entire crystal lattice can be made by consistently reproducing the sample on the device cell in all Instructions.
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
These advancements include unique buildings with programmable lattice symmetries and nicely-defined crystal behaviors, responsive products that leverage the intrinsic Homes of nucleic acids to control constructions on need, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals which provide insights into light–issue interactions. Looking ahead, we challenge the community to leverage the extraordinary structural Management afforded by crystal engineering with DNA to synthesize lessons of useful products that thrust further than what has long been doable with Obviously taking place crystalline components or All those made by additional traditional tactics.
We've composed about around three hundred stones while in the mineral kingdom! Examine Just about every stone's exceptional origin, record, and energies underneath.
. These four structures comprise many of the binary crystals with equal quantities of cations and anions.
Not all crystals type in drinking water, but almost all crystals form precisely the same way, atoms occur together and become a uniformed cluster. The procedure can take as tiny as a couple of days to maybe a thousand many years. Normal crystals that originate from the Earth variety the exact same way.
时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：
11I thoroughly opened the deal and located a crystal bell inside of.我小心地打开包裹，发现里面有一个水晶钟。
水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。

Crystals are not merely renowned for their physical overall look, but unique crystals of various resources and formations may end up in an unlimited selection of uses and Actual physical Houses.
Crystals are labeled generally groups, which include insulators, metals, semiconductors, and molecular solids. Just one crystal of an insulator is normally clear and resembles a bit of glass. Metals are shiny Except if they may have rusted. Semiconductors are occasionally shiny and sometimes transparent but are under no circumstances rusty. Quite a few crystals can be classified as just one sort check here of sound, while others have intermediate behaviour. Cadmium sulfide (CdS) can be ready in pure form and is a wonderful insulator; when impurities are included to cadmium sulfide, it results in being a fascinating semiconductor.
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。
