摘要
太空是人类继陆地、海洋、大气层之后的第四活动领域。第四活动领域具有高真空、微重力、强辐射、改变昼夜节律等特点,为人类的发展带来了巨大的潜力和开发前景。以发展载人航天器为重点的、由航天员参与的载人航天技术是以对太空进行探索以及利用太空环境进行科学研究、资源开发与应用的综合工程技术,它是新技术群中的一个重要领域,是高技术密集的尖端科学技术。文章从载人航天技术的概念、内容和发展载人航天技术的意义三个方面对载人航天技术进行阐述,说明载人航天技术对人类社会发展的重要性。文章还对世界载人航天技术发展的概况与未来的发展做了介绍,最后提出了中国发展载人航天技术的设想。
Space is the fourth activity field after land, ocean and aerosphere. It is characterized by vacuum, microgravity, stronger radiation and so on. There are many potential values for researching and exploring. Since the dawn of the manned space program more than 30 years ago, it has played an important role in taking human to space, and exploiting space wealth. The manned space program is introduced on the concept, content and signification in this article, and especially three manned spacecraft—spaceship, space shuttle and space station is described. The author emphasizes that developing manned space program and utilizing space will make a great contribution in promoting the progress of mankind. In addition, the author also imagines Chinese manned space program. [
