其它描述:《庶物异名疏》中说: �?水精出大秦国,一名黎�?�?。结晶完整的水晶晶体,就如参差交错的马齿,所以人们又叫它马牙石。先民们最早用它研磨成眼镜片,因而送它一个眼镜石的绰号。水晶有通称,也有俗称。广州一带称水晶叫晶玉,又名鱼脑冻;江苏东海县山民发现水晶会 �?窜火�?�?,于是给它起个放光石的俗名。世间一物多名,不足为奇,而像水晶拥有这么多的别称,实不多见。瞧,从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等,简直构成一部奇石鉴赏史。
①压电效�?在机械力(压力或拉�?作用下,水晶单晶体的两端会产生电荷,其电量相等但符号相反。在工业上,无色、无缺陷、不具双晶的水晶常被用来作压电石英片。
These innovations incorporate exotic constructions with programmable lattice symmetries and nicely-outlined crystal behaviors, responsive materials that leverage the intrinsic Qualities of nucleic acids to govern constructions on desire, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals that supply insights into light-weight–matter interactions. Hunting ahead, we obstacle the community to leverage the remarkable structural Management afforded by crystal engineering with DNA to synthesize courses of useful materials that press outside of what is attainable with The natural way developing crystalline products or those made by more common tactics.
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。
水胆水晶,包括气态,液态,固态,有时候可以同时多态并存,无色居多,个别情况下可见红色,绿色,黄色,蓝色,黑色等。
Learn how the shape from the crystals ascertain the different minerals into familiesMinerals crystallize In keeping with amongst 7 motifs, called crystal techniques.
水晶内部有多种矿物包裹体,形成的各种景观可以肉眼观测,这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石,因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性,具有极高欣赏和收藏价值。
Hexagonal �?Characterized by four axes, 3 of which are equivalent in duration and intersect at a hundred and twenty degrees, that has a fourth axis perpendicular to another three.

被主体水晶所捕获的包裹体。原生包裹体通常为固相,形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等,也会见到岩石碎屑或集合体。
The sodium chloride crystal lattice is characterized via the near packing with the good sodium ions and damaging chloride ions. Every single sodium ion is surrounded by six chloride ions, and each chloride ion is surrounded by 6 sodium ions, creating a remarkably stable and symmetrical structure.
⑤、打孔:是在水晶成品未完成前,根据其所需打孔之尺寸及位置,以钻头加工,如制表件、笔筒、瓶孔等。
One more form of crystalline carbon relies on the molecule with sixty carbon atoms called buckminsterfullerene (C60). The molecular shape is spherical. Every single carbon is bonded to 3 neighbours, as in graphite, and the spherical form is Crystal attained by a mixture of 12 rings with 5 sides and 20 rings with 6 sides. Identical buildings ended up first visualized through the American architect R. Buckminster Fuller for geodesic domes.
