Detailed Notes on Crystal

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。

A basic concept in crystal constructions will be the device mobile. It's the smallest unit of quantity that enables similar cells to be organized jointly to occupy all accessible Place. The geometrical foundation of all crystals is the lattice. A lattice may be seen as an everyday and infinite arrangement of points or atoms, where by Just about every position or atom has an identical bordering ecosystem.

对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正,浓度较高,内部无瑕为好。种类上紫晶最贵,其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。

水碧:《山海经》中,水晶又被称作水碧: �?又南三百里,日耿山,无草木,多水碧 �?,郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用,晋代郭景纯《璞江赋》道�?�?鬼,水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉,水精谓之玉瑛也�?”

第二种是“半包裹体”,在水晶结晶以后,由于受到地球引力的影响而产生的裂隙,晶体外的一些物质通过水晶的裂隙渗透到水晶内部,一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹,常被称为“通道”,这种包裹体所形成的景象相对地较受自然环境和时间的影响,相应的价值也比较�?。

Crystals look distinctive from a number of other rocks and minerals, but �?barring a few Particular instances �?nearly all minerals disguise a crystalline framework beneath the surface area.

Crystals may be grown beneath average ailments from all 92 Normally developing features except helium, and helium could be crystallized at low temperatures by utilizing twenty five atmospheres of strain.

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 grown in a laboratory change 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。

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。

The composition of the sodium atoms by yourself, or even the chlorine atoms by yourself, is fcc and defines the unit mobile. The sodium chloride composition Consequently is created up of two interpenetrating fcc lattices. The cesium chloride lattice read more (Figure 3A) is predicated around the bcc structure; each individual other atom is cesium or chlorine. In such cases, the unit mobile is actually a dice. The third essential composition for AB

21You all know how after you take a crystal prism and go a beam of daylight through it, you can get a spectrum, which appears like a steady band of rainbow hues.
