| 摘 要： | 本文采用Reinders的氧化还原缓冲液的方法研究硫敏化的立方体卤化银微晶的敏化中心和潜影中心的氧化还原性能.实验结果表明:1)Reinders的氧化还原缓冲液的方法,不仅可用于研究潜影中心,也可用于研究敏化中心;2)本实验条件下的硫化银敏化中心的氧化还原电位约略负于－220 mV(相对于饱和甘汞电极),潜影中心的氧化还原电位值是介于－220 mV与－190 mV之间(相对于饱和甘汞电极);3)潜影中心的氧化还原活性较敏化中心大得多.

| Abstract: | Reinders' redox buffers were used to study the redox properties of sensitivity centers and latent image centers on microcrystals of cubic silver bromide emulsion in this paper. The results showed that: 1) reinders' redox buffers were used to study the redox properties not only for latent image centers but also for sensitivity centers; 2) The redox potential of Ag_2S sensitivity centers was less negative than -220*!mV with respect to the saturated calomel electrode in our experiment and the redox potential of latent image centers was between -220*!mV and -190*!mV; 3) The redox activities of latent image centers were much higher than that of sensitivity centers. |
