通常对照相乳剂成熟的时间,采用在支持体上涂布乳剂,干燥作成试片,经曝光、显影、定影后用密度计测定显影密度来控制。该方法手续繁杂,时间长,已成为乳剂制造技术进步的主要障碍之一。美国专利2,590,830曾提出用液体状态的乳剂,研究其经曝光、显影后的特性的感光测定方法。 Usually the emulsion phase of the emulsion, coated with an emulsion on the support, dried to prepare a test piece, after exposure, development, fixation and densitometer after the determination of the development density to control. This method is complicated and time-consuming, and has become one of the major obstacles in the progress of emulsion manufacturing technology. U.S. Patent No. 2,590,830 has proposed a method of photographic determination of its properties after exposure and development using a liquid emulsion.
