摘　　要：目的 :针对高原野外环境下移动式富氧室的搭建问题,研制一种质轻便携、无需安装、展收迅速、实用性强的气肋型弥散富氧充气帐篷。方法:采用气肋型网格骨架、优质聚氯乙烯(polyvinyl chloride,PVC)材料、嵌套式结构设计、缓冲门结构、新风弥散通道、废气回收管路等研制新型充气帐篷,配合自行研制的高原弥散富氧机迅速搭建移动式富氧室,分别选用20、50、70、100 m^3/h 4个流量挡次的高原弥散富氧机对富氧帐篷进行连续8 h富氧新风弥散,对比分析富氧帐篷内部(5个分散点)氧气、二氧化碳体积分数的变化曲线。结果:20 m3/h富氧机与帐篷搭配使用效果最佳,弥散8 h后帐篷内部富氧浓度可达27%以上,但同时帐篷内二氧化碳体积分数升高到1 800 ppm(1 ppm=1×10-6)左右,且富氧速度略慢(达到25%左右需3 h)。结论:该气肋型弥散富氧充气帐篷搭配20 m^3/h富氧机在海拔5 000 m可将帐篷内部等效海拔降低到3 000 m以下,能够很好地解决部队在高原野外环境下缺氧的困扰,通过优化改进有望在高原部队中推广使用,成为帮助高原官兵提高战斗力的利器。Objective To develop a ribbed, oxygen-enriched and inflatable tent to fulfill the requirements for mobile enriched oxygen supply under plateau conditions. Methods The tent was developed with ribbed skeleton, PVC material, nested structure, buffer door, channel for fresh air dispersion, exhaust recovery pipeline and etc, and the self-developed plateau oxygen enrichers were involved in to establish a mobile oxygen-enriched room. The enrichers were divided into four grades of 20, 50, 70 and 100 m3/h, which were used to execute 8-h oxygen-enriched fresh air dispersion in the tent. The change curves of the fractions for oxygen and carbon dioxide were compared and analyzed at 5 disperse points in the tent. Results Optimal effect was acquired with 20 m3/h oxygen enricher, the oxygen concentration reached 27% in the tent after 8-h dispersion, while the carbon dioxide fraction was 1 800 ppm（1 ppm=1×10^（-6））and it took 3-h to raise oxygen concentration to25%. Conclusion The tent combined with 20 m3/h oxygen enricher decreases the equivalent altitude from 5 000 m to less than 3 000 m, and is hopeful to be spreaded in the plateau troops after improvement.
