纳米技术是当前全球都在讨论的热门话题,被称为21世纪科技发展的制高点,是新工业革命的主导技术。 (一) 纳米是一种长度单位,1纳米=10-9,即十亿分之一米,大约相当于10个氢原子并排起来的长度,或一根头发丝的百万分之一。所谓纳米技术,是指用数千个分子或原子制造新型材料或微型器件的科学技术。纳米技术涉及的范围很广,纳米生物学,纳米电子学,
Nanotechnology is a hot topic currently discussed all over the world. It is called the commanding height of the 21st century science and technology development and is the leading technology of the new industrial revolution. (a) Nano is a unit of length, 1 nanometer = 10-9, which is one-billionth of a meter, approximately equal to the length of 10 hydrogen atoms arranged side by side, or one millionth of a hair filament. Nanotechnology refers to the science and technology that uses thousands of molecules or atoms to make new materials or micro devices. Nanotechnology involves a wide range of nanobiology, nanoelectronics,
