水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。
23Sometimes, nonetheless, the crystal form of the silicate inclusions is observed to resemble more intently the internal composition of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。
If you wish to see how crystals are fashioned, it is possible to perform a little job as part of your quite possess kitchen and see the formation from the crystals manifest using your possess eyes . This can be finished by Placing a little degree of desk salt into some typical faucet h2o, hold out 24 several hours, and you'll see good cubed formations. This happens since the h2o is evaporating, which will cause the atoms that make up the salt (the mineral) as well as drinking water to come nearer together.
看抛光：抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。
, has a similar composition, but There's two options for choosing the holes the atoms will occupy. The 3rd layer is often positioned above the atoms of the primary layer, generating an alternate layer sequence A
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。
Hexagonal �?Characterised by 4 axes, a few of that are equal in size and intersect at 120 levels, with a fourth axis perpendicular to one other three.
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
Within the Cambridge English Corpus We are saying the chain topology in the substantial w area acts given that the proverbial ' scratch-on-theglass ' essential while in the organic chemistry laboratory to produce crystals. Through the Cambridge English Corpus Consistent-strain and temperature molecular-dynamics simulations of crystals on the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. From the Cambridge English Corpus In combination with these, dust particles happen to be noticed in small-temperature plasmas, like All those Employed in plasma processing and plasma crystals. From the Cambridge English Corpus The ultimate Component of the guide concentrates on peculiarities of strongly coupled dusty plasmas, such as the development of dust crystals and linked attractive forces. Through the Cambridge English Corpus Comprehensive characterization of damage threshold in titanium read more doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. Through the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or even more irregular, Key morphologies were not noticed. Within the Cambridge English Corpus See all examples of crystal These illustrations are from corpora and from sources on the net. Any views from the examples do not represent the belief on the Cambridge Dictionary editors or of Cambridge College Press or its licensors.
隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。
The composition with the sodium atoms by itself, or the chlorine atoms alone, is fcc and defines the unit mobile. The sodium chloride structure Consequently is manufactured up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) is based around the bcc structure; every single other atom is cesium or chlorine. In this instance, the unit cell is a dice. The third significant composition for AB
水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光，都可以在包裹体水晶种找到缩影。
