摘要
对低温系统的预冷过程作了分析，研讨了各种因素对预冷过程的影响。介绍了预冷耗液量计算公式的推导，给出了ＬＨｅ、ＬＨ２、ＬＮ２和ＬＯ２预冷比耗液量的计算图，利用计算图可以方便地计算预冷耗液量。
In this paper,the cool-down process of a cryogenic system is analysed and the factors that influence cool-down process are discussed.The development of formulas for calculating cool-down liquid requirement is represented.The graphs for calculating cool-down liquid requirement are given. The cool-down liquid requirement can be easily determined by means of these graphs.
