摘要
超细微粒的尺度介于原子、分子与块状物之间，直径约为１～１００ｎｍ，居于微观粒子与宏观物体交界的过渡区域本文简洁介绍超细微粒的物理特性、化学特性。
The size of ultra-fine particle intermediate between atom,particle and blocked objects with a diameter of approximately 1～100 nm lies in the joint transition region of micro-particle and macra-objects A brief introduction is given here about the physical property, chemical characteristics,characteristics of magnetism and optics, and its different synthetic methods
