A solid is crystalline if it's got prolonged-range buy. Once the positions of the atom and its neighbours are recognised at 1 stage, the area of every atom is understood precisely all through the crystal. Most liquids lack long-range purchase, although a lot of have small-array buy. Brief array is defined as the first- or second-closest neighbours of the atom. In lots of liquids the main-neighbour atoms are arranged in the identical structure as from the corresponding strong section.
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。
一般而言，紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅，颜色较深的为A级，稍浅的为B级。一般颜色较深的价格高，但要以不深暗为标准。颜色包括两种，一种是水晶本身的颜色，另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正，分布要均匀，不能太深或太浅，如澳州玉、蓝玉髓、紫晶、黄水晶，其价格就高。无色的水晶内含包裹体的颜色艳丽，其价格也高，如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。
诗中道出一段唐代由盛变衰的史实。玄宗末年，杨贵妃得宠，三姐妹并封为国夫人。他们养尊处优，奢华至极，仆人用水晶盘将珍馐佳肴端到宴席上，美人觉得没有口味，懒得动筷子。作为“诗圣”作为“史诗”，紫驼一段写饮食之精美，不空发议论，只尽情揭露事实，无一刺讥语，无一慨叹声，却使人于以外得之：此诗之善讽也。以史为鉴，这样的世道，这样的人物，国家不出“安史之乱”那样的大祸反倒不正常了。
C2 [ U ] transparent glass of incredibly high-quality, commonly with its surface Slash into fragile styles:
Not all crystals variety in drinking water, but nearly all crystals type the identical way, atoms arrive jointly and turn into a uniformed cluster. The method normally takes as minimal as a few days to possibly a thousand decades. Pure crystals that come from the Earth sort exactly the same way.
对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。
②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
Q.4. What's the difference between atomic structure and crystal structure? Ans. The key distinction between atomic framework and crystal composition lies within their definitions: atomic composition refers to how atoms are organized inside a single molecule or even a cluster of molecules, While crystal composition worries the precise arrangement of atoms in a strong material.
The definition of a solid seems clear; a strong is mostly thought of as staying really hard and organization. Upon inspection, nonetheless, the definition gets much less straightforward. A cube of butter, by way of example, is tough right after remaining stored within a refrigerator which is Evidently a stable. Following remaining about the click here kitchen counter for daily, the same dice becomes rather delicate, and it is unclear Should the butter must continue to be considered a strong.
There are 2 these feasible periodic arrangements. In Every single, the first layer has the atoms packed into a aircraft-triangular lattice in which each atom has 6 instant neighbours. Figure 2 demonstrates this arrangement for that atoms labeled A
Crystallography is definitely the research of crystals, and it bargains with all the things from perfect geometric designs to seemingly random conglomerations of particles and minerals.
在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
A different type of crystalline carbon relies with a molecule with sixty carbon atoms called buckminsterfullerene (C60). The molecular form is spherical. Each individual carbon is bonded to three neighbours, as in graphite, plus the spherical shape is attained by a mixture of 12 rings with 5 sides and 20 rings with six sides. Very similar buildings were initially visualized with the American architect R. Buckminster Fuller for geodesic domes.
