美国加州的三位科学家 R.J.Cicerone、S.Elli-ot 和 R.P.Turco 最近提出了在冬季往同温层注入乙烷或丙烷以减弱南极臭氧空洞的形成的建议。根据他们的计算,如在冬季往极地上空的同温层中注入成吨的乙烷或丙烷,用以捕捉氯原子以干扰造成臭氧浓度下降的链反应可能是一种有效的方法。他们同时强调,由于在科学技术上、法律上和伦理上还有不少问题需要考虑,如是否会产生其他的副作用,要用上百架大型飞机去释放5万吨左右的乙烷,释放的时间应当最
Three scientists from California, USA, R.J.Cicerone, S.Elliot, and R.P.Turco, recently proposed a proposal to inject ethane or propane into the stratosphere in winter to weaken the formation of the Antarctic ozone hole. According to their calculations, it may be an effective method to inject tons of ethane or propane into the stratosphere over the polar regions in winter to capture chlorine atoms to interfere with chain reactions that cause a drop in ozone concentration. At the same time, they stressed that since there are still many legal and ethical issues that need to be considered in terms of science and technology, such as whether there will be other side-effects or not, hundreds of large aircraft will be required to release about 50,000 tons of ethane, Time should be the most
