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。
Another exciting, and tasty, experiment is to type substantial crystals working with sugar. By heating sugar with h2o and after that allowing this Option evaporate on sticks, it is possible to type rock candy from sugar crystals!
A primary concept in crystal constructions will be the device mobile. It's the smallest device of volume that allows similar cells to generally be stacked with each other to fill all House. By repeating the pattern of the device cell time and again in all directions, all the crystal lattice may be produced. A dice is The only example of a unit cell. Two other examples are demonstrated in Determine one. The first may be the device cell for a facial area-centred cubic lattice, and the second is for the overall body-centred cubic lattice. These structures are described in the following paragraphs.
诗中道出一段唐代由盛变衰的史实。玄宗末年，杨贵妃得宠，三姐妹并封为国夫人。他们养尊处优，奢华至极，仆人用水晶盘将珍馐佳肴端到宴席上，美人觉得没有口味，懒得动筷子。作为“诗圣”作为“史诗”，紫驼一段写饮食之精美，不空发议论，只尽情揭露事实，无一刺讥语，无一慨叹声，却使人于以外得之：此诗之善讽也。以史为鉴，这样的世道，这样的人物，国家不出“安史之乱”那样的大祸反倒不正常了。
Crystalline construction is characterised by a geometrical, repeating sample of symmetric molecular framework. The arrangement of atoms types these requested, repeating styles.

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。

水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。
The definition of the strong appears apparent; a solid is generally thought of as remaining difficult and organization. Upon inspection, on the other hand, the definition gets to be less straightforward. A dice of butter, by way of example, is hard soon after currently being stored inside a refrigerator and it is Obviously a solid. Right after remaining around the kitchen area counter for daily, exactly the same cube gets rather gentle, and it's unclear Should the butter must even now be regarded a strong.
16I opened the box and observed a piece of crystal snowflake in addition to a greeting card with "Pleased Birthday" while in the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。
You will discover only a few diverse unit-cell designs, so many different crystals share an individual device-cell style. A very important characteristic of the device cell is the number of atoms it has. The total range of atoms in the whole crystal could be the range in Each and every mobile multiplied by the quantity of unit cells. Copper and aluminum (Al) Each individual have one atom for every unit cell, although zinc (Zn) and sodium chloride have two. Most crystals have only a few atoms per unit mobile, but there are a few exceptions. Crystals of polymers, for instance, have A large number of atoms in Every single device cell.
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
crystal Alteration is variable: absent in lots of crystals, in others generating dense sericite aggregates which can demonstrate some recrystallization effects to produce coarser-grained white mica. With the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes arranged in aggregates. Through the Cambridge English Corpus Also, haloarchaeal cells were embedded in just salt crystals under laboratory disorders and subsequently analysed by light microscopy. In the Cambridge English Corpus The white clouds (ordinarily sparse) have been also commonly viewed as getting made up of tiny crystals of drinking water ice, instead like cirrus in our atmosphere. With the Cambridge English Corpus They are located in evaporite salt lakes and may be trapped in salt crystals during evaporation. With the Cambridge English Corpus As a result, the cells (organelles and membranes) are destroyed mechanically by ice crystals, bringing about here Loss of life as a result of mobile lysis. With the Cambridge English Corpus The crystals were used in the primary or 2nd orders of reflection. In the Cambridge English Corpus Within our 8xperiments, the crystals ended up cubes using a base region of eight e mm. In the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : effect of temperature and tension.
