This concept applies Similarly in a single, two, and a few-dimensional Areas. Your complete crystal lattice is often built by regularly reproducing the sample on the device cell in all directions.
杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。
看做工：水晶制品加工过程分为两种，即磨工和雕工。如水晶项链、手链、耳环等属于研磨品；观音像、内画鼻烟壶等属于雕刻品。
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。
. These four structures comprise many of the binary crystals with equal figures of cations and anions.
Lattices could have just one lattice stage for every cell or more than one, yielding a complete of fourteen Bravais crystal lattice varieties. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the three-dimensional array created by a set of discrete details.
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
Crystals is usually developed under reasonable situations from all ninety two By natural means transpiring features except helium, and helium might be crystallized at reduced temperatures by utilizing 25 atmospheres of strain.
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
幽灵水晶，分绿幽灵，红幽灵，白幽灵等，主要组成为绿泥石，其中绿幽灵属于珍贵品种。
看孔眼：对于缀穿水晶制品（如项链、手链、佛珠），要看孔眼是否平直，孔的粗细是否均匀，有无细小裂纹。孔壁必须清澈透明，无“白痕”。
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 Evaluate chronicles above 20 years of exploration into creating a genetic code for crystal engineering. In lieu of directing Organic processes, this code works by using artificial sorts of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2nd and 3D crystalline architectures, in which almost each individual element of the resultant buildings can be systematically managed. Within this conceptual framework, the structural and practical improvements are explained in order to determine the current degree of sophistication and to forecast future directions on the read more System.
矿物成分：针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶，如发晶、钛晶、绿幽灵等，发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶；含铁�?；呈金黄色或柠檬�?)称黄水晶；含锰和钛呈玫瑰色者称蔷薇石英，即粉水晶；烟色者称烟水晶；褐色者称茶晶；黑色透明者称为墨晶。
