摘　　要：本文通过在乳化过程中对碘化钾加入位置的调整研究了碘化钾对颗粒形态比以及照相性能的影响,得出了随着碘化钾在溴碘化银晶体的外移,晶体的形态比逐渐增大,并且在一定形态比的范围内乳剂的感光度随着颗粒的增大而增加的结论。It was disclosed that the influence of potassium iodide to the aspect ratio and sensitivity of the silver bromoiodide emulsion through the adjustment of the position of potassium iodide added in the silver bromoiodide grain. Draw a conclusion that the aspect ratio of grain increased with the moving of the potassium iodide＇s position from inside to outside of the silver bromoiodide grain and the sensitivity increased with increasing paricles in the scope of certain aspect ratio.
