[参考译文]纳米尺度上的科学技术是革命性的。纳米技术是指操纵单独的原子和分子,彻底使用分子级的构筑原料制造机器或创造材料和结构,通过控制结构来设计性能的能力。在纳米世界里,物体的度量衡为纳米——十亿分之一米。一纳米大约有一个原子宽度的四倍,比人的一根头发宽度的千分之一还要细。纳米技术几乎可以改变所有的东西——从 The science and technology at the nanoscale are revolutionary. Nanotechnology refers to the manipulation of individual atoms and molecules, the thorough use of molecular-level building materials to make machines or the creation of materials and structures, and the ability to design properties by controlling structures. In the nanometer world, the weights and measures of objects are nanometer-billionths of a meter. A nanometer is about four times the width of an atom, which is less than one thousandth of the width of a human hair. Nanotechnology can change almost everything - from
