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。
23Sometimes, even so, the crystal method of the silicate inclusions is observed to resemble more intently The interior composition 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。
A crystal structure concentrates on how the atoms are organized inside the crystal. On the other hand, crystallographers are interested in the general condition and sizing on the crystal and also its exterior traits. To perform this, they should learn about the crystal program.
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 structure is characterised by a geometric, repeating pattern of symmetric molecular composition. The arrangement of atoms kinds these requested, repeating styles.
发晶,包括钛晶,铜顺发,绿发晶,黑发晶,银发晶,杂色发晶,其中钛晶最珍贵,少数钛晶价值可比钻石,红宝石和蓝宝石以及祖母绿。
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位,而对水晶来说,颜色和净度(水晶行业称作晶体)是近乎同等重要的因素:
②固体包裹体:指呈固态相存在包裹体,多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
13Nearly all computer systems include a quartz-crystal clock to control their Procedure.几乎所有的计算机都有一个石英晶体时钟来调节它们的运行。
晶体 Silicon crystals developed within a laboratory transform gentle into electrical Electrical power. 在实验室中长成的硅晶体可将光线转变为电能。
There's two this kind of attainable periodic arrangements. In Each and every, the initial layer has the atoms packed right into a aircraft-triangular lattice in which each atom has 6 fast neighbours. Determine 2 displays this arrangement for that atoms labeled A
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹,这种裂纹有大有小,对水晶的影响也有大小之分。
《古今小说·李公子救蛇获称心》:“器皿皆是玻璃、水晶、琥珀、玛瑙为之,曲尽巧妙,非人间所有。”
The C60 molecules, also called buckyballs, are quite strong and almost incompressible. Crystals are shaped this kind of the balls are organized within an fcc lattice having a one particular-nanometre spacing between the centres of adjacent balls. The similar C70 molecule has The form of a more info rugby ball; C70 molecules also type an fcc crystal when stacked with each other. The strong fullerenes sort molecular crystals, with weak binding—furnished by van der Waals interactions—between the molecules.
