航天员进入太空 ,迎接他们的是失重、宇宙辐射等恶劣的环境。这样的环境对其他生物会产生哪些影响呢 ?航天科技将人类以及人类的朋友———各种生物带入太空领域 ,并一步步揭开这些生物科学的难题。1 996年 1 2月 ,科学家在“和平号”空间站的暖棚里播下了墨西哥杂交小麦 ,经过 Astronauts enter space and greet them with harsh environments such as weightlessness and cosmic radiation. What influence will such an environment have on other organisms? Aerospace science and technology will bring humans and human friends, all kinds of living things, into the field of space and step by step to open up these biological science problems. In February 1 996, scientists planted Mexican hybrid wheat in a warm shed on the Mir station.
