17These rings are indicative in the crystal framework of nickel and will be explained only by invoking wavelike Houses of sunshine.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
Bismuth (Bi) appears to get a steel, but the number of electrons readily available for electrical conduction is comparable to that of semiconductors. In reality, bismuth is called a semimetal. Molecular solids usually are crystals formed from molecules or polymers. They may be insulating, semiconducting, or metallic, according to the form of molecules inside the crystal. New molecules are repeatedly getting synthesized, and a lot of are created into crystals. The quantity of distinct crystals is gigantic.
晶及其石英岩类玉石是中低档宝玉石，虽比不上钻石、红蓝宝石的高贵，但在加工中如果构思巧妙而且加工精细，同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
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�?”

⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。
Crystals are nothing at all greater than an ordered arrangement of molecules or atoms. Crystals are available many alternative shapes and sizes, and each one has unique traits. Whatever they are made of establishes how it will eventually variety.
Crystals will often be considered as a little something of huge beauty, plus they are generally made use of with diamonds or other stones to produce parts of jewellery. Many crystals now are male-manufactured in laboratories.
晶体 Silicon crystals developed inside of a laboratory change gentle into electrical Electrical power. 在实验室中长成的硅晶体可将光线转变为电能。
. The second layer is shaded in the determine. It's got the same aircraft-triangular construction; the atoms sit in the holes fashioned by the main layer. The very first layer has two equivalent sets of holes, but the atoms here of the next layer can occupy only one established. The third layer, labeled C
You'll find just a few distinct unit-mobile designs, so many different crystals share one unit-cell form. An essential attribute of the unit cell is the quantity of atoms it has. The entire amount of atoms in all the crystal would be the amount in each cell multiplied by the number of unit cells. Copper and aluminum (Al) Every have a person atom for each device mobile, although zinc (Zn) and sodium chloride have two. Most crystals have only a few atoms per unit mobile, but there are several exceptions. Crystals of polymers, as an example, have Many atoms in Just about every unit cell.
crystal, any strong substance during which the element atoms are organized in a very definite pattern and whose surface area regularity reflects its interior symmetry.
