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。
An additional enjoyable, and delicious, experiment is to type massive crystals applying sugar. By heating sugar with water then letting this Resolution evaporate on sticks, you are able to kind rock sweet from sugar crystals!
These innovations include unique constructions with programmable lattice symmetries and properly-defined crystal routines, responsive products that leverage the intrinsic properties of nucleic acids to control constructions on need, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals that offer insights into light-weight–subject interactions. Searching ahead, we challenge the Neighborhood to leverage the amazing structural control afforded by crystal engineering with DNA to synthesize courses of practical materials that drive past what has actually been achievable with naturally happening crystalline resources or those made by more conventional approaches.
Add to term checklist Include to word record C2 [ U ] clear glass of incredibly superior quality, commonly with its surface Reduce into fragile designs
You will also find lots of components that resemble crystals but are actually polycrystals. Polycrystals form when microscopic crystals fuse collectively to form a stable. These elements tend not to consist of purchased lattices.
Lattices can have a single lattice position for click here each mobile or multiple, yielding a total of fourteen Bravais crystal lattice types. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the 3-dimensional array created by a set of discrete details.
⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果
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 computers incorporate a quartz-crystal clock to regulate 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。
幽灵水晶，分绿幽灵，红幽灵，白幽灵等，主要组成为绿泥石，其中绿幽灵属于珍贵品种。
The basic units of solids are possibly atoms or atoms that have merged into molecules. The electrons of the atom shift in orbits that form a shell structure throughout the nucleus. The shells are crammed in a systematic get, with Each individual shell accommodating only a small number of electrons. Unique atoms have diverse figures of electrons, that happen to be dispersed inside of a characteristic electronic framework of loaded and partially filled shells.
The arrangement of the atom’s electrons decides its chemical properties. The Homes of solids usually are predictable from your Houses of their constituent atoms and molecules, and different shell buildings of atoms are for that reason accountable for the variety of solids.
水精：水晶为何称为水精，《广雅》有巧解：�?水之精灵�?”；李时珍则说：�?莹洁晶光，如水之精英 ”。细加考究，此称还蕴含浓厚的宗教意味呢。水精一名，最初见于佛书，后汉支曜翻译的《具光明定意经》说：�?其所行道，色如水�?�?。
水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光，都可以在包裹体水晶种找到缩影。
