一、前言潜影中心的形成,无疑是银盐感光材料的根本性问题,是制造条件与曝光条件共同形成的结果。胶片涂层中乳剂颗粒潜影中心生成条件的综合表现,决定了该胶片的感光特性和画面质量。对潜影的研究引起了人们的很大兴趣,并形成了不同的理论观点。关于潜影中心几何尺寸的测定也作了不少工作。Hillson 等人应用 Thomson 效应,确定了潜影中心几何尺寸与氧化还原电位的关 I. Introduction The formation of latent image center is undoubtedly the fundamental problem of silver salt photosensitive material, which is the result of the common manufacturing conditions and exposure conditions. The overall performance of the emulsion particle latent image center in the film coating determines the photographic characteristics and picture quality of the film. The research on latent images aroused people’s great interest and formed different theoretical views. About the determination of the geometric center of the latent image also made a lot of work. Hillson et al. Applied the Thomson effect to determine the relationship between the latent image center geometry and the redox potential
