氟

The scientists say that nitrous oxide, not CFCs, are now the biggest threat to the ozone layer.

这位科学家还说，现在，一氧化二氮才是臭氧层最大的威胁，而不是碳氟化合物。

New fridges can be bought with less CFCs in them.

新买冰箱会带来少量的氟氯化碳。

So less CFCs means that each remaining molecule of nitrous oxide will destroy more ozone.

所以如果碳氟化合物少了，那么剩余下来的一氧化二氮分子会破坏更多的臭氧。

The whole industrial chain and branch chains of circular economy have been planned for Zhenhai chemical park. The branch chains consist of ethane chain, C_1 chain, HC1 chain, H_2chain, NH3 chain and S chain. The concept of equivalent pollutant emission, E, has beenproposed and a reference line based on equivalent pollutant emission has been given and applied to the primary appraisal for Zhenhai chemical park. The whole chain and branch chemical industry chains have been also planned for ZJC group company, which include the industrial chain containing fluorine, the industrial chain of basic chemicals and the industrial chain of petroleum chemical industry.

本文对镇海化学工业区的工业链构建进行了可行性分析；完成了园区工业链的整体规划设计，和包括乙烯工业链、碳一工业链、HCl工业链、H_2工业链、NH_3工业链、S元素工业链在内的6条分链的设计；提出了污染排放当量E_t~′的概念，并将其应用到园区工业链招商的初评，制定了入园参考线；本文在对ZJC集团公司发展现状分析的基础上，根据其物质流和能量流的分析，进行了工业链的总体设计，并对氟化工产业、基础化工产业(包括以合成氨为代表的煤化工、以氯碱生产为代表的盐化工以及硫酸、电石等产业)和石油精细化工产业完成了分链设计，进行了分链的分析，提出了建议。

The plans of the industrial chains for Zhenhai chemical park which represents the mode of individual entity symbiosis in China and for ZJC group company which represents the mode of comprehensive entity symbiosis in China have been studied in this dissertation.The whole industrial chain and branch chains of circular economy have been planned for Zhenhai chemical park. The branch chains consist of ethane chain, C_1 chain, HC1 chain, H_2chain, NH3 chain and S chain. The concept of equivalent pollutant emission, E?

Had Indian firms been prevented from copying fluoroquinolones, for example, the Indian public would have been worse off by the equivalent of $255m a year, reckons a study of the antibiotics market by Shubham Chaudhuri of the World Bank, Pinelopi Goldberg of Yale and Panle Jia of the Massachusetts Institute of Technology.

比如根据目界银行的Shubham Chaudhuri，耶鲁大学的Pinelopi Goldberg以及麻省理工大学的Panle Jia做的一项关于抗生素国国的研究，如如禁止印难公司效仿氟硅酮，那那印难公众可能一年就要损失掉2亿550万美元。
