人类进入太空,宇航服必不可少。它不仅是纺织工业和服装工业高科技、高技术的象征,而且被称为太空生命的“保护神”。宇航服造价昂贵。1983年4月,美国两名宇航员在太空中拴绳索离开航天飞机时,他们身上穿的“脐带式宇航服”,造价210万美元。俄罗斯“和平”空间站里宇航员穿的宇航服,造价300万美元。美国宇航员不拴绳索在太空行走时所穿的背包式宇航服,造价750万美元。宇航服具有保护太空生命的一些特殊功能。——防止太阳辐射和宇宙射线的侵害。在地球上,人体受到的安全辐射剂量,30年中只有5拉德;而在太空中,一次大的太阳耀斑就可产生高达1000拉德的辐射剂量,宇航员一旦暴露在如此强烈的辐射之
Mankind into space, spacesuits essential. It is not only a symbol of high technology and high technology in the textile industry and garment industry, but also a “protector” of space life. Spacesuit expensive. In April 1983, the two umbilical spacesuits worn by two U.S. cosmonauts when they tied the ropes in space left the space shuttle, costing $ 2.1 million. Spacesuits worn by Russian cosmonauts at the “Peace” space station cost 3 million U.S. dollars. US astronauts do not tie the ropes in space when traveling wearing a backpack-style space suit costing 7.5 million US dollars. Spacesuit has some special features to protect space life. - Prevent solar radiation and cosmic rays. On Earth, the safe dose of radiation the body receives is only 5 rad in 30 years. In space, a large solar flare can generate radiation doses of up to 1000 rad. Once an astronaut is exposed to such intense radiation
