摘　　要：本工作中,用几种硫杂冠醚化合物对八面体溴化银乳剂进行增感试验。结果表明硫杂冠醚化合物能明显增加乳剂的感光度。用介电损耗法测量了增感后乳剂的离子电导,同时用电子显微镜观察了硫杂冠醚化合物对AgBr乳剂颗粒形状的影响。Study of the sensitization of octabedral AgBr emulsion by several kinds of thia-crown ether compound is reviewed. The result shows that the sensitiv ity of the emulsion was increased appreciably with the addition of thia-crown ether compounds. The ionic conductivity of the sensitized emulsion was measured using the dielectric loss method. The effect of thia-crown ether compounds on the shape of AgBr crystals were observed with electron microscope.
