摘要: 本文就照相乳剂敏化过程中的某些因素,如化学敏化时间、pAg和pH,对低照度互易律失效(LIRF)的影响作了初步的研究。实验结果表明,随着化学敏化时间的增长,照相乳剂的LIRF降低。在一定范围内,提高化学敏化过程中的乳剂的pH和降低pAg,有利于提高乳剂的低照曝光的感光度,改善其低照互易律特性。

Abstract: The Influence of chemical ripening time, pH and pAg on Low-Intensity Reciprocity Failure (LIRF) was inverstigated after chemical ripening of photographic emulsion in this paper.With the increase of the chemical ripening time, LIRF of photographic emulsion is decreased. In the suitable range, the increase of pH and the decrease of pAg in the emulsion after chemical ripening is of benefit to enhancing the sensitivity in the low-intensity exposure and improving the low-intenreciprocity characteristics.

Key words: emulsion preparation, sensitivity, LIRF
