A strong is crystalline if it's extended-selection get. When the positions of the atom and its neighbours are regarded at one point, the place of each and every atom is understood precisely all through the crystal. Most liquids lack very long-selection order, Even though many have quick-assortment order. Small assortment is outlined as the first- or 2nd-closest neighbours of an atom. In many liquids the main-neighbour atoms are organized in the exact same structure as inside the corresponding good section.
12He experimented with yet again in many other towns and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正，浓度较高，内部无瑕为好。种类上紫晶最贵，其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。

You can also find a lot of supplies that resemble crystals but are literally polycrystals. Polycrystals variety when microscopic crystals fuse jointly to sort a reliable. These components tend not to encompass ordered lattices.
Lattices may have 1 lattice position for each mobile or multiple, yielding a total of 14 Bravais crystal lattice kinds. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the a few-dimensional array made by a list of discrete points.

仿制钛晶树水晶：钛晶是水晶里价格最昂贵的，造假者当然也不会放过这么好的产品。天然的环境下，在水晶里能生长个像树一样的钛晶，完全是可能的，只是这样的货很少，那我们的造假专家是如何做的呢，白水晶底下打个洞，激光打点成板状的钛晶进去，就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面，会采用将钛晶部位割成板状，与圆面的水晶粘合的方法来制作。
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。
用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
The composition with the sodium atoms on your own, or the chlorine atoms by yourself, is fcc and defines the unit mobile. The sodium chloride composition Hence is manufactured up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) is based over the bcc construction; each other atom is cesium or chlorine. In cases like this, the device cell is actually a dice. The third essential construction for AB
crystal Alteration is variable: absent in several crystals, in Many others producing dense sericite aggregates which may present some recrystallization consequences to provide coarser-grained white mica. From your Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are occasionally organized in aggregates. With the Cambridge English Corpus Furthermore, haloarchaeal cells were embedded inside of salt crystals below laboratory conditions and subsequently analysed by light-weight microscopy. Within the Cambridge English Corpus The white clouds (usually sparse) had been also greatly considered becoming made up of small crystals of h2o ice, instead like cirrus inside our atmosphere. Through the Cambridge English Corpus They are located in evaporite salt lakes and may be trapped in salt crystals all through evaporation. Through the Cambridge English Corpus Therefore, the cells (organelles website and membranes) are destroyed mechanically by ice crystals, bringing about death by way of mobile lysis. With the Cambridge English Corpus The crystals were used in the very first or second orders of reflection. From your Cambridge English Corpus Inside our 8xperiments, the crystals had been cubes having a foundation space of eight e mm.
