摘要
基于汞污染物特征,介绍了地气界面间汞交换通量研究现状,详细阐述了目前广为使用的通量箱法的优缺点,在分析讨论箱体法过程的基础上,结合冰雪条件应用和本科教学创新实验的目标,对传统箱体法提出了若干改良设计,并初步探索了应用改良箱体法进行冬季研究的主要内容,本研究是本科生教学实验改革与创新的有益尝试。
Based on the characteristic of mercury as a pollutant, the research status on the mercury exchange flux between earth surface and air was introduced and the advantages and disadvantages of the flux chamber method used widely in the world were illustrated finely. Furthermore, some improved designs were put forward on the basis of analysis on the flux chamber method and objects of application under ice and snow conditions and undergraduate experimental teaching innovation. In addition, the main research contents with improved flux chamber winter were exploited preliminary. This paper was a beneficial attempt to the innovation and reform on the undergraduate experimental teaching, generally.
