众所周知,在地球大气层中存在着臭氧层.它对地面热辐射起着平衡作用,为人类生存提供了条件.但是,随着工业的发展,臭氧层遭到了较为严重的破坏,以致出现了“臭氧空洞”.现在臭氧浓度全球性降低已成为事实.究其原因,除了工业生产污染外,还有人类每年频繁向空间发射航天器也是一个重要原因.初看起来,发射航天器对大气的臭氧影响不大,因为火箭飞行时间极短,仅数分
As we all know, there is the ozone layer in the Earth’s atmosphere, which plays a balancing role on the heat radiation on the ground and provides the conditions for human survival. However, with the development of industry, the ozone layer has been severely damaged, resulting in “ozone hole” Now that the global reduction of ozone concentration has become a reality, in addition to industrial pollution, there is also an important reason why humans frequently launch spacecraft into space each year, and at first glance, the spacecraft has little effect on atmospheric ozone , Because the rocket flying time is very short, only a few minutes
