⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。
10This is the silicon chip—a little bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
Crystalline framework is characterized by a geometric, repeating pattern of symmetric molecular composition. The arrangement of atoms varieties these purchased, repeating designs.
Learn the way The form from the crystals figure out different minerals into familiesMinerals crystallize In line with among seven motifs, referred to as crystal units.
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�?

看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。
There are two these possible periodic arrangements. In Each individual, the very first layer has the atoms packed into a plane-triangular lattice in which every atom has six immediate neighbours. Determine two shows this arrangement for the atoms labeled A
The sodium chloride crystal lattice is characterised because of the near packing on the optimistic sodium ions and unfavorable chloride ions. Each and every sodium ion is surrounded by six chloride ions, and every chloride ion is surrounded by 6 sodium ions, developing a extremely steady and symmetrical structure.
水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟，喜欢将它们摆在家里或办公室里，认为水晶球有灵性，能保平安，带来财运。不过天然水晶不像看起来那么晶莹剔透，它也有瑕疵，我们在选购饰品的时候要注意。此外，我们还要掌握水晶的评价依据、选购方法，这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
crystal Alteration is variable: absent in several crystals, in others creating dense sericite aggregates which can show some recrystallization effects to supply coarser-grained white mica. From your Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are occasionally arranged in aggregates. Within the Cambridge English Corpus Also, haloarchaeal cells had been embedded inside salt crystals underneath laboratory disorders and subsequently analysed by gentle microscopy. From your Cambridge English Corpus The white clouds (typically sparse) were also commonly regarded as being composed of little crystals of h2o ice, alternatively like cirrus inside our ambiance. In the Cambridge English Corpus They can be found in evaporite salt lakes and can be trapped in salt crystals for the duration of evaporation. From the Cambridge English Corpus Therefore, the cells (organelles and membranes) are destroyed mechanically by ice crystals, leading to Demise by way of mobile lysis. Within the Cambridge English Corpus The crystals were Employed Crystal in the 1st or 2nd orders of reflection. With the Cambridge English Corpus Within our 8xperiments, the crystals have been cubes by using a foundation space of eight e mm. Within the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : influence of temperature and strain.
