1 纳米技术简介1.1 纳米与纳米技术纳米 (nanometer,nm)是一种度量单位 ,1nm =10 - 3μm =10 - 6 mm =10 - 9m。一个纳米相当于十个氢原子并排起来的长度[1] 。目前国际上公认 0 1～10 0nm为纳米尺度空间。也有人把尺寸 10 0～ 10 0 0nm视为亚微米体系 ,尺寸 1～ 10 0nm划分
1 Introduction to Nanotechnology 1.1 Nano and Nanotechnology Nanometer (nm) is a unit of measurement, 1nm = 10 - 3μm = 10 - 6 mm = 10 - 9m. A nanometer is equivalent to ten hydrogen atoms in length [1]. At present, it is recognized internationally that 0 1 to 100 nm is a nanoscale space. Some people also regard the size of 10 to 100 nm as a sub-micron system with a size of 1 to 100 nm.
