看颜色:即使在同一种类的水晶中,它的不同部位的纹理、色泽也各式各有千秋。属于单色的,要色度均匀;在同一块水晶上有深浅的,则要求其色调纹路美观大方。

③、粗抛光:是将模具压出之毛胚,以金刚石盘直接磨出成品之刻线。④、细抛光:在粗抛光之后,以抛光粉来磨成品至晶莹剔透为止。

发晶的价值取决于发的颜色、罕见性及大小,一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态,便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值,通过它们可了解几百万年前地球上水的成分及变化。

Encyclopaedia Britannica's editors oversee issue locations through which they may have substantial understanding, whether or not from a long time of working experience acquired by working on that content material or via study for a sophisticated diploma. They produce new content and confirm and edit information acquired from contributors.

看抛光:抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。

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�?”。

The elements are found in many different crystal packing preparations. The most common lattice constructions for metals are All those received by stacking the atomic spheres into probably the most compact arrangement.

包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。

22Working from what The usa now appreciates about itself, the bureau's experts along with other demographers provide an irresistible, if clouded, crystal ball among the their visions.

15The trick to a great thermoelectric product is actually a crystal composition by which Crystal electrons can flow freely.制造一种好的热电材料的关键是,需要一种电子可以自由流动的晶体结构。

The sodium chloride crystal lattice is characterized by the near packing on the positive sodium ions and negative chloride ions. Each individual sodium ion is surrounded by 6 chloride ions, and each chloride ion is surrounded by 6 sodium ions, making a extremely stable and symmetrical structure.

水精:水晶为何称为水精,《广雅》有巧解:�?水之精灵�?”;李时珍则说:�?莹洁晶光,如水之精英 ”。细加考究,此称还蕴含浓厚的宗教意味呢。水精一名,最初见于佛书,后汉支曜翻译的《具光明定意经》说:�?其所行道,色如水�?�?。

The C60 molecules, also referred to as buckyballs, are rather robust and Just about incompressible. Crystals are formed these which the balls are organized within an fcc lattice that has a a person-nanometre spacing between the centres of adjacent balls. The identical C70 molecule has The form of the rugby ball; C70 molecules also variety an fcc crystal when stacked collectively. The good fullerenes type molecular crystals, with weak binding—furnished by van der Waals interactions—between the molecules.
