17These rings are indicative in the crystal construction of nickel and might be spelled out 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。
③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。
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。
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
Crystalline framework is characterized by a geometric, repeating sample of symmetric molecular construction. The arrangement of atoms kinds these purchased, repeating patterns.

30Three days went previous, and I had been amazed to find out it all over again: many of the openings were sewed up by slim and white thread and they appeared such as ice crystal on Winter season's branches in the north.
发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。
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。
[ C/U ] clear glass of top of the range, typically with its area Minimize into patterns that mirror light
There are two such probable periodic arrangements. In Every, the 1st layer has the atoms packed into a plane-triangular lattice in which each atom has 6 quick neighbours. Determine two reveals this arrangement for that atoms labeled A
You'll find other minerals and molecules that may kind these crystal lattices. Snowflakes certainly are a basic example of a about symmetric and geometrically patterned framework from ice crystals, and gemstones of all varieties are usually crystals.
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
Binary crystals are present in a lot of constructions. Some pairs of factors variety more than one composition. click here At home temperature, cadmium sulfide could crystallize both in the zinc blende or wurtzite composition. Alumina also has two possible structures at place temperature, α-alumina (corundum) and β-alumina. Other binary crystals show diverse constructions at distinct temperatures. One of the most complex crystals are These of silicon dioxide (SiO2), that has seven different structures at many temperatures and pressures; the most common of these buildings is quartz.
