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。
Bismuth (Bi) seems to be a steel, but the amount of electrons readily available for electrical conduction is analogous to that of semiconductors. In truth, bismuth is named a semimetal. Molecular solids are generally crystals formed from molecules or polymers. They may be insulating, semiconducting, or metallic, with regards to the type of molecules inside the crystal. New molecules are continually becoming synthesized, and several are created into crystals. The amount of distinctive crystals is big.
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。

水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
Ionic Crystals: Electrostatic forces type ionic bonds. A traditional illustration is a halite or salt crystal.
水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：
颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。

The arrangement of the atom’s electrons decides its chemical click here properties. The Houses of solids are frequently predictable in the Qualities of their constituent atoms and molecules, and different shell constructions of atoms are therefore answerable for the diversity of solids.

crystal Alteration is variable: absent in lots of crystals, in Some others manufacturing dense sericite aggregates which may present some recrystallization results to supply coarser-grained white mica. Through the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are occasionally arranged in aggregates. With the Cambridge English Corpus Moreover, haloarchaeal cells have been embedded within just salt crystals beneath laboratory problems and subsequently analysed by light-weight microscopy. From your Cambridge English Corpus The white clouds (usually sparse) have been also greatly considered being composed of little crystals of h2o ice, alternatively like cirrus inside our atmosphere. Within the Cambridge English Corpus They can be found in evaporite salt lakes and might be trapped in salt crystals in the course of evaporation. From the Cambridge English Corpus Consequently, the cells (organelles and membranes) are wrecked mechanically by ice crystals, bringing about Dying through mobile lysis. Within the Cambridge English Corpus The crystals had been Utilized in the very first or second orders of reflection. From the Cambridge English Corpus In our 8xperiments, the crystals were cubes using a foundation spot of eight e mm. From your Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : influence of temperature and stress.
