“纳米”是“nanometer”译名 ,即为毫微米 ,通常用“nm”表示。在物理学中 ,纳米是长度的单位 ;一纳米为十亿分之一米。所谓“纳米科技” ,就是在 0 1～ 1 0 0纳米的尺度上 ,研究和利用原子、分子的结构、特征及相互作用的高新科学技术(Crandall等 ,1 992 )。用纳米技术制备? “Nanometer” is the name of “nanometer”, which means nanometer, usually expressed by “nm”. In physics, nanometers are units of length; one nanometer is one billionth of a meter. The so-called “nanotechnology” is a high-tech science that studies and utilizes the structure, characteristics and interactions of atoms and molecules on a scale of 0 1 -100 nanometers (Crandall et al., 1992).
