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。
①压电效�?在机械力(压力或拉�?作用下，水晶单晶体的两端会产生电荷，其电量相等但符号相反。在工业上，无色、无缺陷、不具双晶的水晶常被用来作压电石英片。
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。
If you'd like to see how crystals are shaped, you may do a little undertaking in your really own kitchen and see the development with the crystals manifest together with your have eyes . This can be accomplished by Placing a small quantity of desk salt into some typical tap h2o, wait 24 hrs, and you will see great cubed formations. This occurs because the drinking water is evaporating, which leads to the atoms which make up the salt (the mineral) plus the h2o to return closer with each other.
You will also find several materials that resemble crystals but are actually polycrystals. Polycrystals type when microscopic crystals fuse jointly to sort a strong. These components do not include purchased lattices.
发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。
Crystals are sometimes seen as one thing of immense magnificence, and they are commonly made use of with diamonds or other stones to help make pieces of jewellery. Many crystals now are male-designed in laboratories.
crystal The newly crystallized quartz grains are characterised by elongate crystals oriented oblique towards the shear band margins, defining a typical grain-shape foliation. 来自 Cambridge English Corpus We are saying the chain topology during the substantial w region functions because the proverbial ' scratch-on-theglass ' essential inside the natural and organic chemistry laboratory to help make crystals. 来自 Cambridge English Corpus The age scatter between the individual crystals might mirror incorporation of xenocrysts from previously magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene forms neutral to pale brown, subhedral to anhedral crystals, at times containing inclusions of plagioclase microlaths and opaque phases.

Crystallography is the review of crystals, and it discounts with almost everything from fantastic geometric shapes to seemingly random conglomerations of particles and minerals.
This Overview chronicles around here two decades of exploration into making a genetic code for crystal engineering. Rather than directing Organic processes, this code takes advantage of synthetic sorts of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which just about each individual aspect of the resultant constructions is usually systematically managed. Within just this conceptual framework, the structural and practical advances are explained in order to define the present standard of sophistication also to forecast future Instructions of your platform.
Fig. five: The chance to recognize described crystal practices is dependent on the symmetry engineering tactic.
