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 generally be a metallic, but the volume of electrons available for electrical conduction is comparable to that of semiconductors. In actual fact, bismuth is named a semimetal. Molecular solids usually are crystals formed from molecules or polymers. They are often insulating, semiconducting, or metallic, depending upon the type of molecules within the crystal. New molecules are continually staying synthesized, and a lot of are made into crystals. The amount of various crystals is gigantic.
Chemical Bonds The types of chemical bonds shaped amongst atoms or groups of atoms in crystals rely upon their dimension and electronegativity. There are four classes of crystals as grouped by their bonding:
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。
How Crystals Variety The whole process of forming a crystal is known as crystallization. Crystallization usually happens when a solid crystal grows from a liquid or Option.
, has exactly the same construction, but There are 2 decisions for selecting the holes that the atoms will occupy. The third layer might be placed around the atoms of the initial layer, making an alternate layer sequence A
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。

第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
晶体 Silicon crystals developed in the laboratory convert mild into electrical energy. 在实验室中长成的硅晶体可将光线转变为电能。
From your Cambridge English Corpus We are saying the chain topology while in the high w area acts as the proverbial ' scratch-on-theglass ' desired within the organic and natural chemistry laboratory to create crystals. From the Cambridge English Corpus Consistent-pressure and temperature molecular-dynamics simulations of crystals with the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. In the get more info Cambridge English Corpus In combination with these, dust particles have already been observed in small-temperature plasmas, like People Employed in plasma processing and plasma crystals. From the Cambridge English Corpus The final Section of the reserve concentrates on peculiarities of strongly coupled dusty plasmas, such as the formation of dust crystals and linked interesting forces. Within the Cambridge English Corpus Entire characterization of injury threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. From your Cambridge English Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, primary morphologies were not noticed. Through the Cambridge English Corpus See all samples of crystal These examples are from corpora and from sources on the internet.

隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。
在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
