摘要
本文用受阻显影技术和电镜研究方法研究了显影剂量对显影液中银成核速度和核分散度的影响。随着显影液中显影剂量的减小,卤化银颗粒上银的成核速度明显减慢,单个颗粒上显影中心的数目明显增加。实验结果表明显影液中银的成核过程和曝光后的潜影形成过程在机理上是有差别的。文章讨论了显影过程中的一些基本问题:可显性、临界尺寸和显影选择性等等。
The influence of the amount of developing agent contained in developer on the nucleation rate and the dispersity of nucleus was investigated.The results show that the nucleation rate decreases and the number of nucleus on single emulsion grain increases with decreeing amount of developing agent.It implies the differences in mechanism between the two processes,of which one is silver nucleation in developer and the other is latent-image formation.Some principle problems concerning photographic development,such as,developability,critical size and development selectivity are discussed.
