李商隐，杜牧，白居易，欧阳修，苏轼，呈大昌，辛弃疾，杨万里，吴文英，杨基，魏源等诗坛，词林大家都有歌吟水晶的佳篇传世。
杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。
These advances include things like exotic structures with programmable lattice symmetries and effectively-described crystal practices, responsive elements that leverage the intrinsic properties of nucleic acids to control constructions on desire, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals that supply insights into light-weight–issue interactions. Wanting ahead, we challenge the community to leverage the remarkable structural Regulate afforded by crystal engineering with DNA to synthesize lessons of purposeful components that thrust outside of what is achievable with naturally occurring crystalline components or Individuals made by much more standard strategies.
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。
Fig. four: Constructing blocks with various shapes and surface chemistries direct the development of distinct crystal symmetries.
Monoclinic �?Characterized by a few unequal axes, two of which intersect at an oblique angle, when the third is perpendicular to the plane of another two.
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。
Crystals could be developed less than moderate ailments from all 92 In a natural way developing factors apart from helium, and helium could be crystallized at lower temperatures through the use of twenty five atmospheres of pressure.
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。

Single crystals of metals are comfortable and malleable, when polycrystalline metals are more durable and stronger and website are more handy industrially. Most polycrystalline products can be built into substantial solitary crystals immediately after extended heat remedy. In the past blacksmiths would warmth a bit of metal to really make it malleable: heat tends to make a handful of grains mature huge by incorporating lesser types. The smiths would bend the softened metallic into shape and after that pound it awhile; the pounding would make it polycrystalline all over again, raising its strength.

水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
Another sort of crystalline carbon relies with a molecule with 60 carbon atoms termed buckminsterfullerene (C60). The molecular shape is spherical. Just about every carbon is bonded to three neighbours, as in graphite, along with the spherical condition is obtained by a mix of 12 rings with 5 sides and twenty rings with six sides. Similar buildings had been very first visualized via the American architect R. Buckminster Fuller for geodesic domes.
