１纳米等于１０亿分之一米。纳米技术是指在纳米尺度下制造物质，即在单个原子、分子层次上对物质存在的种类、数量和结构形态等进行观测、识别与控制，生产制造出只有几十个到几万个原子的超细化物质即纳米微粒的技术。有人说，纳米技术将会影响２１世纪人们的生活方式。卢柯 One nanometer equals one billionth of a meter. Nanotechnology refers to the manufacture of materials at the nanoscale, ie the observation, identification and control of the species, quantity and structure of the material at the individual atomic and molecular levels to produce only tens to tens of thousands of atoms Superfine material that nano-particles technology. Some people say that nanotechnology will affect people’s way of life in the 21st century. Lu Ke
