| 摘 要： | 氧化亚氮(N2O)是大气中重要和微量的温室气体,且在平流层N2O形成NO自由基与O3发生反应破坏臭氧层.海洋是大气中N2O净源,但由于海洋中生物化学过程的复杂性,有关N2O形成机制至今是人们研究的重点和难点.应用稳定同位素分馏原理对海洋中N2O形成机制的研究,区分海洋中通过硝化和反硝化过程不同途径产生的N2O过程,为深入研究海洋中N2O循环、估算将来大气中N2O浓度变化提供有用工具.

| Abstract: | Nitrous oxide(N2O) is an important and trace greenhouse gas in the atmosphere.N2O would form NO free radicals in the stratosphere to destruct the ozone layer in reaction with O3 ion.Although the ocean is a net source for atmospheric N2O,it is necessary to understand the mechanism of N2O formation due to marine biological chemical process complexity.A stable isotope fractionation principle would be applied to distinguish N2O formation mechanism in oceans between nitrification and denitrification processes,wh... |
