摘　　要：利用U-3010紫外可见分光光度计检测了不同增感条件下AgCl立方体乳剂的光吸收谱。实验结果表明：化学增感后样片的光吸收谱基本与未增感样片的一致，光谱与化学共同增感后样片的光吸收谱与光谱增感样片类似，在可见光长波波段475～510nm明显增加了AgCl乳剂对光的吸收，化学增感对卤化银的光吸收没有影响，并且与光谱增感之间不存在负面影响。The absorption spectrums have been measured with U-3010 spectrophotometer in AgCl emulsions. The absorption spectrum of chemical sensitization was consistent with that of unsensitization. The absorption spectrum of spectral sensitization distinctly increased the absorption in the long wave range. The spectrum of chemistry and spectral sensitization was like that of spectral sensitization. The results indicated that chemical sensitization has no effect on the light absorption of silver halide, and that there is no negative effect between chemical sensitization and spectral sensitization.
