卤化银照相乳剂的感光测定,一般是把照相乳剂涂布在支持体上,干燥后用光楔曝光,经过显影、定影,用密度计测量光楔片密度,但是,所需要的时间较长,在美国专利2590830中介绍过液态乳剂的感光测定方法。过去对液态照相乳剂的感光测定如图1(Ⅰ)所示。先把液体照相乳剂10用量杯11计量后,倒入透明容器12内作为验测试样13。以光源14照射透明容器内的试样乳剂13,在液体状态下进行曝光,然后加入一定数量的显影液15到乳剂内,用搅拌器16搅动显影,最后,在显影后的试样乳剂13加入定影液17,使之停止显影。这时,通过光源18,平行光管19和受光器20对试样乳剂13的光学密度进行测
The photographic determination of silver halide photographic emulsions is generally performed by coating the photographic emulsion on a support, exposing it to light wedge exposure after drying, developing, fixing, and measuring the density of optical wedges using a densitometer, however, the longer the time required, A method of determining the sensitivity of liquid emulsions is described in U.S. Patent 2,590,830. The sensitometric measurement of liquid photographic emulsions in the past is shown in Fig. 1 (I). The liquid photographic emulsion 10 is first metered using a measuring cup 11 and then poured into a transparent container 12 as a test sample 13. The sample emulsion 13 in the transparent container is irradiated with the light source 14 and exposed in the liquid state. Then, a certain amount of the developer 15 is added to the emulsion, agitated and developed by the agitator 16, and finally, the developed sample emulsion 13 is added Fixing liquid 17, to stop the development. At this time, the optical density of the sample emulsion 13 is measured by the light source 18, the collimator 19, and the photoreceiver 20
