摘要： 本文以电沉积在银电极上的溴化银为研究对象,用计时电位法研究了照相染料与溴化银晶体之间的相互作用。结果表明,染料对溴化银过渡时间、还原电位和电还原惰性物生成量均有显著影响,并且生成的电还原惰性物量的多少或平衡常数的大小与照相染料对溴化银乳剂感光度之间有一定的关系。

Abstract: A chronopotentiometry technique for studying the interaction of spectral sensitive dye with silver bromide is described. This method is based on the principle that the transition time of the silver bromide will be reduced with increasing the amount of sensitizing dye-silver bromide inert compound.The experiment indicates that transition time and reduce potential of silver bromide are decreased by addition of the spectral sensitizing dye. The equilibirum constant of the spectral sensitive' dye-silver bromide inert compounds is computed.There are some relation sbetween the amount of the inert compound and the characteristic increasing emulsion sensitivity of the dyes.
