通过对先前报道的暗适应曲线的分析（Pugh（1975）），发现了3种独立成分漂白后存在等效背景强度下降的证据，衰减时间常数为.apprx。 5 秒、100 秒和 7 分钟。结果支持这样的观点，即等效背景是由漂白光产生的中间体导致的杆状光子事件引起的，并且去除这些中间体的模型提供了对心理物理结果的良好描述。这些想法与最近的证明是一致的，即漂白后杆中量子事件的发生率增加（Lamb（1980））。
From analysis of previously reported scotopic dark adaptation curves (Pugh (1975)), evidence was found for the existence following a bleach of 3 separate components in the decline of the equivalent background intensity, with decay time constants of .apprx. 5 s, 100 s and 7 min. The results support the idea that the equivalent background is caused by photon-like events in the rods as a result of intermediates produced by the bleaching light, and a model of the removal of these intermediates provides a good description of the psychophysical results. The ideas are consistent with the recent demonstration of an increased rate of occurrence of quantal events in rods following a bleach (Lamb (1980)).
