摘　　要：目的 :检验移动式救生钟在实施常压干式援救时 ,生命支持系统能否提供常压空间人体生存环境 ,以保证钟内人员的生命安全。方法 :人员进钟后关闭钟盖 ,进行 2次 10人 8h的正常供氧试验及 1次 10人 8h的应急供氧试验 ,并对钟内CO2 浓度及钠石灰的利用率进行分析评价。结果 :3次试验结束时钟内CO2 浓度为 (1.38± 0 .0 2 ) % ;钠石灰利用率为 (6 5±2 ) %。结论 :钟内CO2 浓度在安全范围之内 ;钠石灰性能可靠 ;该生命支持系统能提供安全的人体生存环境。Objective: To evaluate the absorption efficiency of CO 2 canister to see if the life support system will meet the essential environmental conditions, when an atmospheric dry salvage operation is conducted. Methods: Two normal oxygen supply experiments involving 10 subjects and totaling 8 h and one emergency oxygen supply experiment involving 10 subjects for 8h were carried out to analyze the CO 2 level in the bell and also evaluate the efficiency of CO 2 canister. Results: After 3 experiments were completed, the CO 2 level in the bell was (1.38±0.02)%, and the efficiency of CO 2 canister was (65±2)%. Conclusion: CO 2 level in the bell was within safe range and CO 2 canister reliable, demonstrating that the life support system could provide safe environmental living conditions for humans.
