摘　　要：建立了一种可以描述低温推进剂加注、停放过程的计算模型,分析了影响低温推进剂加注停放阶段蒸发的主要因素。研究表明:为缩短发射组织时间、优化加注流程、提升推进剂品质,在全系统能力范畴内,低温推进剂加注过程应提高推进剂加注速度,降低推进剂加注温度,尽量减小外界环境漏热率,并适当增加系统排气能力。The model which was established to describe cryogenic propellant loading and ground-hold process had been quoted to study the main factors of propellant evaporation during loading on ground. The research proved that for the capability of the whole system, in order to minimize the launch preparation time, optimize loading procedure and improve propellant quality, the cryogenic propellant loading procedure should be under the conditions of high propellant loading speed, low propellant loading temperature, reduc- ing environmental leaking heat and enhancing tank venting rate.
