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 elementary idea in crystal buildings would be the device cell. It's the smallest device of volume which allows similar cells to get organized collectively to occupy all accessible House. The geometrical foundation of all crystals would be the lattice. A lattice may be viewed as a daily and infinite arrangement of details or atoms, in which Each individual place or atom has An analogous surrounding surroundings.
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。
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
You can also find several materials that resemble crystals but are actually polycrystals. Polycrystals kind when microscopic crystals fuse jointly to type a stable. These supplies usually do not include purchased lattices.
无色水晶与无色长石因折射率和密度十分接近故较难区分。主要方法是放大检查。长石有两组极完全解理，显微镜下可见两组解理相交而成的“娱蛤状”包裹体或细直的纹理，而水晶则无解理发育，仅有时可见断续不规则的裂理。
解理：无解理。所谓解理是指矿物被打击时，沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类：极完全解理、完全解理、中等解理、不完全解理和无解理，水晶属于无解理。

Q.four. What's the distinction between atomic construction and crystal structure? Ans. The primary distinction between atomic composition and crystal framework lies of their definitions: atomic construction refers to how atoms are organized within a single molecule or simply a cluster of molecules, While crystal composition considerations the precise arrangement of atoms in just a solid material.
crystal The recently crystallized quartz grains are characterized by elongate crystals oriented oblique towards the shear band margins, defining a normal grain-shape foliation. 来自 Cambridge English Corpus We are saying the chain topology while in the large w location acts because the proverbial ' scratch-on-theglass ' necessary inside the organic chemistry laboratory to make crystals. 来自 Cambridge English Corpus The age scatter amid the person crystals could reflect incorporation of xenocrysts from previously magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, sometimes that contains inclusions of plagioclase microlaths and opaque phases.
. The 2nd layer is shaded in the figure. It's got a similar airplane-triangular structure; the atoms sit inside the holes shaped by the very first layer. The main layer has two equivalent sets of holes, however the atoms of the click here 2nd layer can occupy just one set. The 3rd layer, labeled C

⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。
Yet another form of crystalline carbon relies with a molecule with 60 carbon atoms identified as buckminsterfullerene (C60). The molecular condition is spherical. Every carbon is bonded to a few neighbours, as in graphite, and the spherical shape is obtained by a mix of 12 rings with 5 sides and twenty rings with 6 sides. Similar buildings had been first visualized from the American architect R. Buckminster Fuller for geodesic domes.
