摘要: 本文利用显影动力学方法就一种纯溴化银乳剂研究了各乳剂颗粒中不同大小的两类杂质中心的形成情况。结果表明,在通常的敏化和曝光的条件下,乳剂颗粒中较小的杂质中心主要形成于化学成熟过程中,而较大的杂质中心则主要在曝光过程中形成。讨论了这种看法与化学成熟过程和曝光过程的一些主要的动力学特征的相容性。

Abstract: The formation of the two kinds of the largest impurity centres, of different sizes in emulsion grains was investigated by a method based on development kinetics on a pure silver bromide emulsion. The results show that under normal chemical sensitization and exposure conditions the smaller centres in the emulsion grains are formed primarily in the process of chemical ripening, whilst the major of the larger ones formed during exposure. The compatibility of the concept with some major kinetic features of chemical ripening and exposure was discussed.
