摘　　要：舞台液氮输送系统的主要功能是根据舞台喷雾效果需求,向特效设备(雾机)快速提供所需液氮。针对雾机对所供液氮不能含气、随时提供以及系统运行经济性的要求,对舞台液氮输送系统预冷过程进行分析,提出了在满足系统预冷安全情况下,提高系统运行经济性的方法。The main function of the stage liquefied nitrogen conveyance system is nitrogen to the special-effect equipment (misting machine)as per the requirement to fast supply desired liquefied on stage misting effect.As per the requirements of no containing of gas in the liquefied nitrogen supplied by the misting machine,prompt supply at the demanding time,and the economy of the system operation,the pre-cooling process of the stage liquefied nitrogen conveyance system is analyzed,and the method to improve the economy of the system operation under the prerequisite of ensuring safety of the system pre-cooling is proposed.
