8Where do we get this magic wand and crystal ball?我们到哪里获得这种魔棒和水晶玻璃球？
Bismuth (Bi) seems for being a steel, but the amount of electrons available for electrical conduction is comparable to that of semiconductors. In actual fact, bismuth is called a semimetal. Molecular solids tend to be crystals shaped from molecules or polymers. They are often insulating, semiconducting, or metallic, depending on the style of molecules during the crystal. New molecules are continuously becoming synthesized, and many are created into crystals. The volume of various crystals is big.
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。
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�?”

Crystals are absolutely nothing more than an requested arrangement of molecules or atoms. Crystals are available in many alternative shapes and sizes, and each has distinctive characteristics. The things they are created of determines how it'll variety.
水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：
The definition of the sound appears obvious; a strong is mostly thought of as remaining tricky and agency. Upon inspection, nevertheless, the definition gets to be a lot less straightforward. A cube of butter, one example is, is tough immediately after being stored inside of a refrigerator and is particularly clearly a stable. Following remaining to the kitchen area counter for each day, the exact same cube gets to be rather soft, and it is actually unclear if the butter should still be regarded a strong.
Within the Cambridge English Corpus We are saying the chain topology during the superior w location functions since the proverbial ' scratch-on-theglass ' necessary while in the organic and natural chemistry laboratory for making crystals. Within the Cambridge English Corpus Regular-tension and temperature molecular-dynamics simulations of crystals with the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. From your Cambridge English Corpus Together with these, dust particles are actually observed in low-temperature plasmas, like All those Employed in plasma processing and plasma crystals. In the Cambridge English Corpus The ultimate Portion of the guide concentrates on peculiarities of strongly coupled dusty plasmas, including the here formation of dust crystals and involved beautiful forces. Within the Cambridge English Corpus Complete characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. With the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, primary morphologies were not observed. From the Cambridge English Corpus See all examples of crystal These examples are from corpora and from sources on the net. Any opinions from the illustrations do not signify the view from the Cambridge Dictionary editors or of Cambridge University Push or its licensors.
Crystallography would be the review of crystals, and it deals with almost everything from great geometric styles to seemingly random conglomerations of particles and minerals.
The composition in the sodium atoms on your own, or the chlorine atoms by yourself, is fcc and defines the unit cell. The sodium chloride composition Therefore is produced up of two interpenetrating fcc lattices. The cesium chloride lattice (Determine 3A) is predicated around the bcc framework; each individual other atom is cesium or chlorine. In cases like this, the device mobile is often a cube. The 3rd essential framework for AB
