| 摘 要： | 从1999年7月到9月作者与中国极地考察队合作，从北半球中纬度到极极圈地区进行了大规模的气体样品采样，运用气相色谱电子捕获检测器得到了随纬度变化的CFCs的特征浓度，并从地理位置和气象条件对所有样品的趋势进行了分析，研究结果有助于更好的理解北半球发达国家与发展中国家逐步取消卤化碳类化合物的现状和趋势。

| Abstract: | Intensive samples have been collected from mid latitude to polar region in the Northern Hemisphere from July to September in 1999 cooperating with the Chinese Third Antarctic Inland Ice sheet Traversal Party. The latitudinal characteristic concentrations of CFCs have been obtained after analyzing by using gas chromatography with electronic capture detector. The trends of all the samples have been studied with the geographical location and meteorological condition. The result will help to understand the process of the phase out of halocarbon in both developed and developing countries in the Northern Hemisphere. |
