本研究以变形的醋酸胶片为研究对象,分析不同种类胶片经过不同处理后,片基长度发生变化的情况,探寻胶片长度的变化规律,同时观察经各种处理后,胶片在自然状态下尺寸稳定性保持能力。实验中以胶片齿孔距变化为胶片长度变化的主要判断依据,同时检测经过不同处理后胶片密度的变化。
In this study, we took the deformed acetate film as the research object, analyzed the change of the length of the film after the different kinds of films were treated, and explored the changing rules of the film length. At the same time, we observed that after various treatments, the size of the film was stable under natural conditions Maintain ability. In the experiment, the change of the pitch of the film was taken as the main judgment basis for the change of the film length. At the same time, the change of the density of the film after different treatments was detected.
