This idea applies equally in one, two, and three-dimensional Areas. The entire crystal lattice can be made by continuously reproducing the sample from the unit cell in all directions.
③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。
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。
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 are 2 options for choosing the holes which the atoms will occupy. The 3rd layer could be placed in excess of the atoms of the main layer, making an alternate layer sequence A
Crystals seem one of a kind from a number of other rocks and minerals, but �?barring a number of Distinctive situations �?almost all minerals cover a crystalline composition underneath the surface area.
Like a sizzling solution cools or a saturated solution evaporates, particles attract near plenty of for chemical bonds to kind. Crystals may also sort from deposition directly from the fuel stage. Liquid crystals have particles oriented in an structured way, like reliable crystals, however will be able to stream.
水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：
crystal The newly crystallized quartz grains are characterized by elongate crystals oriented oblique towards the shear band margins, defining a typical grain-condition foliation. 来自 Cambridge English Corpus We are saying the chain topology within the high w region acts given that the proverbial ' scratch-on-theglass ' wanted from the organic chemistry laboratory for making crystals. 来自 Cambridge English Corpus The age scatter amongst the person crystals may replicate incorporation of xenocrysts from before magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene types neutral to pale brown, subhedral to anhedral crystals, often containing inclusions of plagioclase microlaths and opaque phases.
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。

A different method click here of crystalline carbon is based over a molecule with 60 carbon atoms known as buckminsterfullerene (C60). The molecular shape is spherical. Each carbon is bonded to 3 neighbours, as in graphite, as well as the spherical form is obtained by a combination of 12 rings with five sides and 20 rings with 6 sides. Similar structures had been first visualized through the American architect R. Buckminster Fuller for geodesic domes.
