摘　　要：采用计算机控制的平衡双注乳化方法制备富氯化银乳剂,通过掺杂溴离子来改善富氯化银乳剂在高照度条件下照相性能。主要对溴离子的掺杂位置、用量对照相性能的影响进行了应用研究。试验结果表明:在卤化银晶体次表层引入适量的溴离子,使制备的氯溴化银乳剂在高照度曝光条件下具有更优异的感光度和肩部反差性能。The rich silver chloride emulsion used in emulsification was prepared with a balanced double jn- jection method controlled by a computer, by doping the bromide ion , the silver chloride emulsion photography performance was improved in high intensity conditon. The effect of doping position on photographic properties, the amount of bromide ion were studied and tested. The results showed that the introduction of bromine ion halo- genated crystal body surface, chloro bromide enmlsion prepared had excellent sensitivity and shoulder contrast per- formance in high intensity exposure conditions.
