专为航线应用的一种分子筛氧浓缩器已研制出来，其性能在低压舱和航线服务中得到评定。在低压舱内迅速减压后在海平面，2000ft，4000fi，6000fi，8000fi，10000ft和25000ft测量了氧的流量和百分含量，要求使用氧深缩器的旅客填齐1份问卷调查，在人力和财力方面与氧气瓶进行评比 A molecular sieve oxygen concentrator specially developed for use in aeronautics has been developed and its performance is assessed in the low pressure compartment and service of the route. After the rapid decompression in the low-pressure cabin at sea level, 2000 ft, 4000 fi, 6000 fi, 8000 fi, 10000 ft and 25000 ft were measured oxygen flow rate and percentage requirements of visitors using oxygen retractors fill in a questionnaire survey in human And the financial aspects of oxygen cylinders and appraisal
