在胶片生产过程中,由于工艺条件和化工原材料性能不稳定等复杂因素的影响,用同一配方制备的感光乳剂,其照相性能往往随批号不同而存在较大差异,这是影响胶片统一性的重要原因之一。对采用光谱增感剂的胶片,乳剂感光度的变化可通过调整增感染料的用量加以补偿;而对不用光谱增感剂的片种或乳剂涂 In the film production process, due to the process conditions and the instability of chemical raw materials and other complex factors, the same formula prepared emulsion, the photographic performance often vary with batch number there is a big difference, which is important to affect film uniformity one of the reasons. The use of spectral sensitizers film, the emulsion sensitivity can be adjusted by adjusting the amount of sensitizing dye to be compensated; and without the use of spectral sensitizers tablets or emulsion coated
