一、照相理论 1.潜影形成理论 1968年世界上有些学派对潜影形成机理的理论进行了探讨。且不论述葛尔尼—莫特早期潜影形成理论或米契尔等人对它以后的修改,只谈及初级照相过程中正空穴的作用就有很多争论。马林诺乌斯基认为,曝光时释出的电子和空穴,在晶体内分别或独立地受到俘获。结构缺陷(位移和颗粒边缘层)所俘获的电子被间隙银离子所中和,从而形成潜影银。空穴不被结构缺陷所俘获,而却被由 First, the photographic theory 1 latent image formation theory In 1968 some of the world’s schools on the latent image formation mechanism of the theory were discussed. Regardless of the early theory of Kernian-Morte’s latent image formation or Mitchell et al’s later modifications, there is much debate over the role of positive cavities in primary photography. Malinowski believes that electrons and holes released during exposure are individually and independently trapped in the crystal. Electrons captured by structural defects (displacement and grain boundary layer) are neutralized by interstitial silver ions, forming latent silver. Holes are not trapped by structural defects, but by
