①就结构而言,碳纳米管可以看作是普通石墨的一个奇异变种。碳纳米管的结构相当于把石墨的平面组织卷成管状,于是黑色的丑小鸭马上就化做美丽的白天鹅,石墨管摇身一变成为纳米科技的新宠。纯碳纳米管每克售价1000元,价格为黄金的10倍。在科学家的手中,碳纳米管就像是魔术棒,不断变换出各种新花样。

1 In terms of structure, carbon nanotubes can be seen as a strange variant of ordinary graphite. The structure of the carbon nanotubes is equivalent to rolling the planar structure of graphite into a tube, so the black ugly duckling immediately becomes a beautiful white swan, and the graphite tube has become the new favorite of nanotechnology. Pure carbon nanotubes are priced at 1,000 yuan per gram, and the price is 10 times that of gold. In the hands of scientists, carbon nanotubes are like magic wands and they constantly transform a variety of new patterns.
