CFC-11及CFC-12替代物及其潜代技术分析林丹玲
We study the temporal evolution of concentrations of the chlorofluorocarbons CFC 11 and CFC 12 in the ocean, under the assumption of circulation and mixing being invariant in time. This allows us to define a time-invariant age distribution for a given point in the ocean, where the age is def...
Estimated historical and future emissions of CFC-11 and CFC-12 in China中国历史上和未来CFC-11和CFC-12的排放量计算 In this paper, the historical and future consumptions and emissions of CFC-11 and CFC-12 in China was estimated based on the consumption data and phase out... WANG Feng,...

The background concentrations of atmospheric CFC-11 and CFC-12were monitored to assess their impact on stratospheric ozone depletion and global warming from September 1995 to March 1999 at Kosan, Korea, located at eastern margin of the Asian Continent. The concentrations of atmospheric CFC-11 at ...
