摘　　要：电影是人类重要的文化遗产之一,然而记录电影的载体电影胶片由于受自身构成材料和保存环境等因素的影响,面临巨大威胁。其中保存环境的温度、湿度是影响电影胶片长期保存的关键因素之一,实践证明低温低湿有利于胶片的长期保存,但温度、湿度过低会导致胶片变脆、变形,降低其机械性能,同时也会增加保存运行成本,增加档案管理工作的复杂性。结合我国的具体国情,我们初步认为电影胶片较为适宜的保存温度范围为-5℃～5℃,相对湿度范围为30%RH～50%RH。The film is one of important cultural heritages of mankind, however, the carrier recording the film is facing a huge threat due to the influence of its own constituting material , the preservative environment and other factors. Actually, the temperature and humidity of the preservative environment is one of the key factors affecting the film long-term preservation. The practice has proved that low temperature and low humidity are beneficial to the film long-term preservation, but the extreme low temperature and humidity will make the film brittle and deformative and reduce the mechanical capability ;meanwhile, it will also increase the cost of preservative operation and the complexity of managing records. In consideration of the China＇s specific national conditions, preliminarily ,we believe that the appropriate temperature range is from -5℃ to 5℃ and relative humidity is in the range of 30%RH-50% RH for the film preservation.
