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。
12He attempted again in quite a few other metropolitan areas and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
结晶的形状非常细小，需要用显微镜才能看得清楚，外观上看起来是平滑、块状。常见最多的是各式玛瑙
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
Monoclinic �?Characterised by 3 unequal axes, two of which intersect at an oblique angle, even though the 3rd is perpendicular on the aircraft of the other two.
⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果
②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
Quite a few crystals behave like butter in that they are hard at lower temperatures but soft at better temperatures. They're identified as solids whatsoever temperatures beneath their melting place. A doable definition of a solid is surely an object that retains its condition if left undisturbed. The pertinent issue is just how long the object retains its shape. A extremely viscous fluid retains its condition for an hour or so but not a 12 months. A sound must hold its condition lengthier than that.
晶体 Silicon crystals grown in a laboratory convert gentle into electrical energy. 在实验室中长成的硅晶体可将光线转变为电能。
16I opened the box and saw a bit of crystal snowflake plus 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。
Crystal Lattices You will find seven systems of crystal buildings, which might be also known as lattices or Area lattices:
Crystals are categorized usually types, such as insulators, metals, semiconductors, and molecular solids. Just one crystal of the insulator is generally clear and resembles a piece of glass. Metals are shiny Except if they have got rusted. Semiconductors are occasionally shiny and at times clear but are hardly ever rusty. A lot of crystals may be categorised as a single sort of sound, while others have intermediate behaviour. Cadmium sulfide (CdS) is usually ready in pure form and is an excellent insulator; when impurities are included to cadmium sulfide, it results in being a fascinating semiconductor.
Tetragonal �?Characterized by 3 mutually perpendicular axes, two of that happen to be equivalent in duration, check here while the third is longer or shorter and perpendicular to the other two.
