A stable is crystalline if it has long-vary purchase. After the positions of an atom and its neighbours are recognised at one issue, the place of each atom is thought specifically through the crystal. Most liquids deficiency lengthy-range purchase, Whilst numerous have quick-variety get. Short range is described as the first- or second-closest neighbours of the atom. In lots of liquids the first-neighbour atoms are organized in the identical framework as during the corresponding strong period.
水晶原石观赏石充分体现了天然水晶的本质，经过抛光的水晶原石观赏石，玲珑剔透、晶莹璀璨，独具匠心的设计，恰到好处地显露出水晶的魅力。如果您想单纯的欣赏水晶，水晶原石观赏石是你的不二之选，给人一种返璞归真的感觉。
A crystal composition concentrates on how the atoms are arranged In the crystal. On the other hand, crystallographers have an interest in the overall shape and size of your crystal and also its external traits. To accomplish this, they have to learn about the crystal system.
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
根据美国已经了解的情况，统计局的专家和其他人口统计学家在他们的视野中提供了一个不可抗拒的水晶球。
⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
The elements are identified in a variety of crystal packing arrangements. The most common lattice buildings for metals are Individuals acquired by stacking the atomic spheres into quite possibly the most compact arrangement.
Crystals are frequently considered as anything of huge attractiveness, and so they are generally applied with diamonds or other stones to produce pieces of jewelry. The majority of crystals now are gentleman-designed read more in laboratories.
crystal The freshly crystallized quartz grains are characterised by elongate crystals oriented oblique towards the shear band margins, defining an average grain-condition foliation. 来自 Cambridge English Corpus We are saying the chain topology while in the large w region acts as the proverbial ' scratch-on-theglass ' required inside the organic chemistry laboratory for making crystals. 来自 Cambridge English Corpus The age scatter amongst the individual crystals may perhaps mirror incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene types neutral to pale brown, subhedral to anhedral crystals, sometimes made up of inclusions of plagioclase microlaths and opaque phases.
⑥、丝印：水晶表面附有不同的色料进行效果处理，颜色层面较厚，着力后方可脱落。
Orthorhombic: These are rhombic prisms and dipyramids that resemble tetragons but devoid of sq. cross-sections.
压电性：水晶晶体受到压力时会产生电荷；反之，受到电压作用时，晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能，称压电性。
The C60 molecules, also referred to as buckyballs, are quite potent and Nearly incompressible. Crystals are fashioned this kind of that the balls are arranged within an fcc lattice which has a one particular-nanometre spacing among the centres of adjacent balls. The equivalent C70 molecule has The form of the rugby ball; C70 molecules also sort an fcc crystal when stacked with each other. The strong fullerenes form molecular crystals, with weak binding—provided by van der Waals interactions—among the molecules.
