当代出舱活动技术发展

Development of Technologies of Extravehicular Activities

出舱活动技术有多种分类方法和广泛用途,并需使用气闸舱、舱外航天服等一些先进而复杂的硬件设备。40多年来,经过苏联/俄罗斯、美国等国的专家的不断开发,出舱活动技术已有了长足的发展。俄美两国在出舱活动系统方面各有特色,在出舱训练技术方面也各有千秋。中国航天员将进行首次出舱活动,成为世界上第3个完全独立实现出舱活动的国家。

Extravehicular activities （EVA） require advanced and complex hardware, such as airlock module and extravehicular spacesuit. In the past 40 years, EVA technology sees a rapid development through the effort in Soviet Union/Russia, the United States and other countries. China＇s first astronauts will carry out EVA, which makes China the world＇s No. 3 country for a full independent EVA.
