飞船遨游太空,航天员始终要在封闭狭小的环境里经受超重、失重相互交替的折磨,要承受噪声、振动、低压、缺氧等许多飞行动力学因素和环境因素的作用,同时还要完成飞船上各种操作任务和大量科学试验任务。如果不训练,人在太空连一般生活都极困难。要克服飞行中的障碍,并胜任飞天任务,千里挑一的航天员必须要经过特殊的训练。他们要进行基础理论、体质、航天环境适应等多种训练。这包括体质训练、理论知识教育、心理训练、特殊环境因素耐力 Spacecraft in space, the astronauts always in a closed environment to withstand overweight, weightlessness alternating with each other to withstand the noise, vibration, low pressure, hypoxia and many other aerodynamic factors and environmental factors, but also to complete the spacecraft On a variety of operational tasks and a large number of scientific experiments. Without training, it is extremely difficult for people to live in common life in space. To overcome the obstacles in flight and be capable of flying astronauts, the astronauts of all walks must undergo special training. They have to carry out a variety of basic theories, physical fitness, aerospace environment and other training. This includes physical training, theoretical knowledge education, psychological training, special environmental factors endurance
