8Where do we get this magic wand and crystal ball?我们到哪里获得这种魔棒和水晶玻璃球?
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。
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。
③次生包裹体:指主体水晶形成后,由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
Crystalline framework is characterised by a geometrical, repeating pattern of symmetric molecular construction. The arrangement of atoms kinds these requested, repeating patterns.
Not all crystals form in h2o, but almost all crystals variety precisely the same way, atoms come jointly and turn into a uniformed cluster. The process can take as minor as a couple of days to probably a thousand years. Pure crystals that originate from the Earth sort exactly the same way.
Springer Nature remains neutral regarding jurisdictional claims in printed maps and institutional affiliations.
26Some of the finest ingesting Eyeglasses are produced from guide crystal.一些最精致的酒杯是用铅晶质玻璃制成的。《柯林斯英汉双解大词典》
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。
晶体 Silicon crystals developed in a very laboratory change mild into electrical Electrical power. 在实验室中长成的硅晶体可将光线转变为电能。
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。
正常的水晶在生长时,多可以发现和柱形尖端棱线平行的生长纹(expansion lines)。由于在地底、岩洞中的生长空间多狭窄,尤其在遇到地震时,或地壳变动时,甚至容易遭到其他矿石的挤压,常常会压迫产生不同的「晶面」。还有,当水晶还是在液态状的时候,常常也会包覆着其他的矿石、泥灰一起结晶成长,如金红石(稍后变成发晶)、火山泥灰(稍后变成幻影水晶)等等。所有的这些,都是「自然的一部分」,请不要视为「瑕疵」。
⑦双色水晶:一种紫色和黄色共存一体的水晶,紫色、黄色之间界限较明显,分别占据晶块的一部分。
crystal Alteration is variable: absent in lots of crystals, in Other folks making dense sericite aggregates which may show some recrystallization consequences to make coarser-grained white mica. In the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes arranged in aggregates. With the Cambridge English Corpus On top of that, haloarchaeal cells ended up embedded inside of salt crystals less than laboratory problems and subsequently analysed by light microscopy. Within the Cambridge English Corpus The white clouds (commonly sparse) were also commonly considered being composed of little crystals of water ice, alternatively like cirrus in our environment. From the Cambridge English Corpus They are present in evaporite salt lakes and may be trapped in salt crystals for the duration of evaporation. Through the Cambridge English Corpus Therefore, the cells (organelles and membranes) are destroyed mechanically by ice crystals, bringing about Dying through mobile lysis. In the Cambridge website English Corpus The crystals ended up Employed in the very first or 2nd orders of reflection. Through the Cambridge English Corpus Within our 8xperiments, the crystals had been cubes that has a foundation place of eight e mm. Within the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and tension.
