| 摘 要： | 大气平流层臭氧（大气臭氧层）由于能够吸收太阳辐射中的高能量紫外线，对人类和生物起着非常重要的保护作用，氯氟烃类化合物（ＣＦＣｓ）已被认为是造成大气平流层臭氧耗损的主要原因，淘汰ＣＦＣｓ和使用替代物日趋紧迫，目前，最有应用前景的替代物是含氢氧氟烃类化合物（ＨＣＦＣｓ）和氢氟烃类化合物（ＨＦＣｓ），其中有些已投入工业使用，本文总结 了ＨＣＦＣｓ和ＨＦＣｓ在气中的光化学降解机制及其产物，以及产物对环境的

| Abstract: | Chlorofluorocarbons(CFCs)have been regarded as the main course for the depletion of stratospheric ozone. To protect the strato-spheric ozone layer, the phaseout of the CFCs and the use of CFC substitutes are being implemented. At present, hydrochlor of luorocar bons(HCFCs)and hydrofluoro-carbons(HFCs)are the most hopeful substitutes, and some of them have been used in the industry. This paper reviews mechanisms and products of photo-chemical deg radation of HCFCs and HFCs in the atmosphere, and the environmental effect of products. |
