A sound is crystalline if it's very long-variety get. As soon as the positions of the atom and its neighbours are regarded at one point, the location of each atom is thought specifically through the entire crystal. Most liquids deficiency extended-array get, While several have shorter-variety buy. Small range is described as the 1st- or second-closest neighbours of the atom. In several liquids the 1st-neighbour atoms are organized in a similar construction as in the corresponding good section.

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：
Insert to term record Increase to term checklist C2 [ U ] clear glass of extremely premium quality, generally with its floor Lower into delicate styles
C2 [ U ] transparent glass of quite good quality, typically with its surface Reduce into delicate styles:
Monoclinic �?Characterised by a few unequal axes, two of which intersect at an oblique angle, while the 3rd is perpendicular on the airplane of another two.
时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：
Crystals are almost nothing more than an ordered arrangement of molecules or atoms. Crystals can be found in many alternative shapes and sizes, and every one has various features. The things they are created of determines how it will eventually sort.
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 newly crystallized quartz grains are characterised by elongate crystals oriented oblique towards the shear band margins, defining a normal grain-condition foliation. 来自 Cambridge English Corpus We are saying the chain topology from the significant w location acts because the proverbial ' scratch-on-theglass ' required while in the organic chemistry laboratory to generate crystals. 来自 Cambridge English Corpus The age Crystal scatter between the individual crystals could reflect incorporation of xenocrysts from previously magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene forms neutral to pale brown, subhedral to anhedral crystals, occasionally containing inclusions of plagioclase microlaths and opaque phases.
天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值，但是包裹体水晶观赏石经常需要适当打磨抛光，这样更方便观赏水晶内部的包裹体。
You can find other minerals and molecules which will sort these crystal lattices. Snowflakes undoubtedly are a basic illustration of a around symmetric and geometrically patterned construction from ice crystals, and gemstones of all versions are generally crystals.
This Evaluate chronicles in excess of twenty years of study into developing a genetic code for crystal engineering. Instead of directing biological procedures, this code uses artificial varieties of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2D and 3D crystalline architectures, in which just about every aspect of the resultant constructions is often systematically controlled. Inside this conceptual framework, the structural and functional developments are described in an effort to define the existing degree of sophistication and also to predict future directions in the System.
