一、应用和研究新技术问题的提出近几年来,国外制氧设备的研究在探索高效、节能的气体分离工艺上取得了令人鼓午的发展,而且它的应用范围已经从七十年代初主要用于工业而扩展到呼吸用氧的军用、民用设备,包括飞机上的设备。美国在这方面的工作是走在前头的。近几年来,报导了行些新法制氧设备,如飞机上 First, the application and research on the issue of new technologies In recent years, foreign research on oxygen equipment in the exploration of efficient, energy-saving gas separation process has made a grueling development, and its scope of application has been from the early seventies Military and civilian equipment that is mainly used in industry to extend to breathing oxygen, including equipment on board aircraft. The United States has taken the lead in this area of ​​work. In recent years, some new statutory oxygen equipment such as airplanes has been reported
