| 摘 要： | 本文从南极比撒哈拉沙漠干燥入手，论证了低温（0℃以下）必干燥。进而引入结合水的“三不”性质，说明在低温冷冻条件下，湿度与结合水相互保持独立的特性。根据物质内部分子运动的一般规律，当引力占了绝对优势的时候，胶片的衰变将出现相对稳定状态。

| Abstract: | Low temperature far below water freezing point means also very low humidity, this is the conclusion deducted from the fact that South Pole is much more dry than Sahara Desert in Africa.The paper points out that at an extremely low temperature,the humidity is independent upon associated water,the gravity will play the decisive role ,the film ageing will delay and become consistent. |
