| Summary: | 氟氯烃（Chlorofluorocarbons，CFCs）在大洋中广泛分布，但不具有生物活性，也不会沉积于大洋，因而在海水中较稳定，20世纪70年代起被应用于海洋水团运动和海气交换的研究，取得优异的成果。本研究以CFCs为化学示踪物，研究白令海、楚科奇海及加拿大海盆等海域环流特征、水团分布及水团年龄。主要研究结果如下： 1、白令海表层水中CFC-11溶解度较低，但是饱和度在100.67%～132.05%之间，为过饱和状态；白令海表层海水中CCl4、CFC-11、CFC-113与CFC-12在57°N均出现极小值，为57°N气旋涡的存在提供有力的佐证；白令海表层水中低含量的CFCs分布特征与高. Chlorofluorocarbons (CFCs) are widely distributed in the ocean, which without biological activity, and would not deposit on the ocean, are stable in seawater. Since 70s of the 20th century, CFCs was applied to study the movement of marine water mass and sea-air interaction, achieved excellent results. In this study, CFCs were used as chemical tracer to study the age of water masses and their movem. 学位：理学硕士 院系专业：海洋与环境学院海洋学系_海洋化学 学号：22420071150872
