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。

景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。
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。
You will find many alternative crystals according to geometric buildings, crystal expansion, and materials. There might be preparations of hexagonal carbon atoms or amethyst that makes hexagonal pyramid structures.
Lattices can have a person lattice point for each mobile or more than one, yielding a complete of 14 Bravais crystal lattice kinds. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the 3-dimensional array made by a list of discrete details.
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。
发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。
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。
⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。

The arrangement of an atom’s electrons determines its chemical properties. The Attributes of solids are usually predictable within the Qualities in their constituent atoms and molecules, and different shell structures of atoms are consequently to blame for the variety of solids.
This Critique chronicles over 20 years of investigate into creating a genetic code for crystal engineering. As opposed to directing biological procedures, this code makes use of artificial varieties of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which almost every single facet of the resultant buildings can be systematically controlled. Within just this conceptual framework, the structural and purposeful improvements are described in an effort to determine the present amount of sophistication and also to forecast foreseeable future Instructions with the platform.
crystal Alteration is variable: absent in several crystals, in Many others developing check here dense sericite aggregates which may present some recrystallization outcomes to make coarser-grained white mica. From the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are occasionally organized in aggregates. From your Cambridge English Corpus Also, haloarchaeal cells were embedded in just salt crystals beneath laboratory ailments and subsequently analysed by mild microscopy. From your Cambridge English Corpus The white clouds (commonly sparse) were being also greatly regarded as remaining composed of small crystals of water ice, somewhat like cirrus in our ambiance. In the Cambridge English Corpus They are located in evaporite salt lakes and will be trapped in salt crystals throughout evaporation. From the Cambridge English Corpus Therefore, the cells (organelles and membranes) are destroyed mechanically by ice crystals, leading to Loss of life by cell lysis. With the Cambridge English Corpus The crystals have been Utilized in the first or 2nd orders of reflection. Through the Cambridge English Corpus Within our 8xperiments, the crystals ended up cubes with a foundation place of eight e mm. From your Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : influence of temperature and force.
