纳米技术时代——“钻石时代”今天的时代被称为信息时代,信息时代后面将是什么时代?科学家们预言说——将是纳米技术时代! 纳米,即毫微米(10~(-9)米),这是一种可以用来量度分子大小的微观尺度。1纳米相当于一个氢原子半径(0.5A°,1A°=10~(-8)厘米)的20倍。1纳米的长度相对于1厘米来说,好比是1厘米相对于100公里。纳米技术,有时又称分子纳米技术,即在原子和分子层次上系统地组织、刻划和操纵物质的技术。我们今天的制造技术,如果从分子层次上来说,其实是非常粗糙的,从铸造、研磨和碾碎,直至最精细的平板印刷刻蚀,在这些制造工艺中所移动的原子都是数目庞大的统计数量级的、即多达几百万以至几十亿
Nanotechnology era - “Diamond Age” Today’s era is called the information age, the era behind the information age? Scientists predict - will be the nanotechnology era! Nanometer, namely nanometer (10 ~ (-9) M), a microscopic scale that can be used to measure the size of a molecule. One nanometer corresponds to 20 times the radius of a hydrogen atom (0.5A °, 1A ° = 10 ~ (-8) cm). A length of 1 nanometer relative to 1 centimeter is like 1 centimeter relative to 100 km. Nanotechnology, sometimes called molecular nanotechnology, is a technique of systematically organizing, characterizing and manipulating matter at the atomic and molecular levels. Our manufacturing technology today is actually very rough at the molecular level, from casting, grinding and milling to the finest lithography etching, where the number of atoms that are moved in these manufacturing processes is huge Statistics, that is, up to millions or even billions
