卤化银成像体系中的纳米化学*

纳米化学研究的对象是尺寸在1 ~100nm的化学实体，它构成了一个介乎微观相和宏观相之间的介观相 (mesoscopic phase)，介观相不仅反映了化学实体在尺寸上从微观向宏观的过渡，而且表现了一系列特殊的效应和功能。本文探讨了纳米化学对卤化银成像体系的冲击和卤化银成像过程的研究对纳米化学的发展所做出的贡献。

Nanochemistry in Imaging System of Silver Halide

Entities with sizes from 1 to 100nm，which form a mesoscopic phase between macroscopic and microscopic phases，are main objects studied in nanochemistry. 'I'he mcso-scopic phase is not only a transition in size from micro toward macro，but also has itself a series of unique behaviors and functions. In this paper the impact of nanochemistry on the imaging system of silver halide and the contributions of studies on imaging process of silver halide to the development of nanochemistry have been investigated.
