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。

水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。

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。

水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。

Monoclinic �?Characterised by three unequal axes, two of which intersect at an oblique angle, while the third is perpendicular for the aircraft of the opposite two.

水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见，所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人，所以通常人们会要求水晶净度越高越好，尽量避免有较明显的内含物的水晶。

You will find there's related directive about crystal glass which differentiates in between whole guide crystal, guide crystal and crystal.

Metallic Crystals: Metals usually sort metallic crystals, where several of the valence electrons are absolutely free to move all through the lattice. Iron, one example is, can sort distinctive metallic crystals.

say cheese a thing that somebody that is getting a photograph of you lets you know to say so that your mouth makes the shape of the smile

There's two such probable periodic preparations. In Each individual, the primary layer has the atoms packed right into a airplane-triangular lattice in which each and every atom has six quick neighbours. Figure 2 exhibits this arrangement for that atoms labeled A

You will discover other minerals and molecules that may form these crystal lattices. Snowflakes certainly are a traditional illustration of a around symmetric and geometrically patterned composition from ice crystals, and gemstones of all kinds are usually crystals.

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�?�?。

The C60 molecules, also known as buckyballs, are fairly potent and Pretty much incompressible. Crystals are shaped this kind of the balls are organized in an fcc lattice which has a 1-nanometre spacing concerning the centres of adjacent balls. The very similar C70 molecule has The form of the rugby ball; C70 molecules also form an fcc crystal when stacked alongside one another. The reliable fullerenes sort molecular crystals, with weak binding—provided by van der Waals interactions—in between website the molecules.
