| 摘 要： | 为了认识玉珠峰冰川区域大气中痕量元素的组成和来源，利用高分辨电感耦合等离子体质谱仪对2009年10月采自玉珠峰冰川海拔5800m的一个75cm雪坑中15种可溶性痕量元素（A1、Fe、Ba、Cd、Co、Cr、Cu、Li、Ni、Zn、Pb、Sb、Sr、U和V）的浓度进行了测试．结果表明：痕量元素的浓度变化很大，从最小值1．...

| Abstract: | In order to understand the composition and sources of the trace elements in the atmosphere over Yuzhufeng Glacier,using the high resolution inductively coupled plasma mass spectrometry,concentrations of the fifteen dissolubility trace elements,i.e.,Al,Fe,Ba,Cd,Co,Cr,Cu,Li,Ni,Zn,Pb,Sb,Sr,U and V,were determined.The samples were collected from a 75-cm snow-pit on the elevation of 5800 m in Yuzhufeng Glacier in October 2009.The analyses indicate that the concentrations of the trace elements have the prodigious... |
