| 摘 要： | 研究了玉珠峰冰川和小冬克玛底冰川雪坑中离子、正构烷烃和多环芳烃的含量及分布特征,并利用正构烷烃和多环芳烃的相关参数以及离子与这两种有机物之间的相关系数探讨了雪坑中这些化学组分的可能来源.结果表明:虽然同受两风环流的影响,但玉珠峰冰川雪坑中离子、正构烷烃和多环芳烃的含量远高于小冬克玛底冰川,这与它们所处的地理位置有关.∑...

| Abstract: | The contents and distribution characteristics of ions,n-alkanes and polycyclic aromatic hydrocarbons within the snowpits in the Yuzhufeng Glacier and Xiao Dongkemadi Glacier were studied.Parameters and correlation coefficients between the ions and two organic compounds were used to explore the possible sources of these chemical compositions.The result indicates that they are both influenced by westerly circulation,but the contents of ions,n-alkanes and polycyclic aromatic hydrocarbons in the Yuzhufeng Glaci... |
