17These rings are indicative with the crystal construction of nickel and will be discussed only by invoking wavelike Homes of light.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。

A essential notion in crystal buildings is definitely the unit mobile. It's the smallest device of quantity that enables similar cells being arranged jointly to occupy all obtainable Area. The geometrical foundation of all crystals could be the lattice. A lattice may be viewed as an everyday and infinite arrangement of points or atoms, in which Every issue or atom has The same surrounding atmosphere.

人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：

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。

There are also lots of supplies that resemble crystals but are actually polycrystals. Polycrystals form when microscopic crystals fuse together to sort a good. These materials do not include purchased lattices.

Monoclinic �?Characterized by three unequal axes, two of which intersect at an oblique angle, even though the 3rd is perpendicular to your aircraft of the opposite two.

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。

Ionic Crystals: Electrostatic forces type ionic bonds. A typical case in point is really a halite or salt crystal.

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。

crystal The freshly crystallized quartz grains are characterised by elongate crystals oriented oblique towards the shear band margins, defining a normal grain-form foliation. 来自 Cambridge English Corpus We say the chain topology while in the large w region functions because the proverbial ' scratch-on-theglass ' desired from the natural and organic chemistry laboratory to generate crystals. 来自 Cambridge English Corpus The age scatter among the individual crystals could replicate incorporation of xenocrysts from previously magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, sometimes containing Crystal inclusions of plagioclase microlaths and opaque phases.

被主体水晶所捕获的包裹体。原生包裹体通常为固相，形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等，也会见到岩石碎屑或集合体。

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。

⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。
