This idea applies Similarly in a single, two, and 3-dimensional Areas. Your complete crystal lattice is often produced by consistently reproducing the pattern in the device cell in all directions.
23Sometimes, even so, the crystal sort of the silicate inclusions is observed to resemble additional closely The interior construction of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
晶及其石英岩类玉石是中低档宝玉石，虽比不上钻石、红蓝宝石的高贵，但在加工中如果构思巧妙而且加工精细，同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
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。
2She was sporting a strand of crystal beads.她戴着一串水晶珠子。《柯林斯英汉双解大词典》
Lattices can have a single lattice stage for every cell or multiple, yielding a total of fourteen Bravais crystal lattice forms. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the a few-dimensional array made by a set of discrete details.
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。
As a warm Resolution cools or maybe a saturated solution evaporates, particles attract near plenty of for chemical bonds to type. Crystals also can type from deposition directly from the gasoline section. Liquid crystals possess particles get more info oriented in an structured method, like solid crystals, still can flow.
Q.four. What's the difference between atomic structure and crystal framework? Ans. The primary distinction between atomic framework and crystal composition lies inside their definitions: atomic composition refers to how atoms are organized in just a one molecule or possibly a cluster of molecules, Whilst crystal structure worries the specific arrangement of atoms inside a reliable substance.
⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。
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。

玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光，都可以在包裹体水晶种找到缩影。
