The ion concentrations were studied in both four snow pits on Hami Miaoergou FlatTopped Glacier and one snow pit on Haxilegen Glacier No.51 of Kuitun river in eastern Tianshan Mountain, and both snow pits were retrieved in 2004. The results show that the Ca2+, NO-3 and SO2-4, particularly Ca2+, are major ions in the snow of snow pits in both ablation and accumulation area and also in the ice of snow pits in accumulation area on Hami Miaoergou FlatTopped Glacier, where the relationships among major cation concentrations in snow of snow pits can be revealed by ion concentrations in the ice of snow pits, but the correlation between ion concentrations in the snow of snow pits and elevation is not obvious, which probably can be attributed to the narrow span of elevation and sparse snow pits on glacier. However, the good correlation between ion concentrations in the ice of snow pits and elevation indicates that the elution process weakened gradually with the elevation rise and temperature decrease.
对2004年获取的天山奎屯河哈希勒根51号冰川1个雪坑和哈密庙尔沟平顶冰川4个雪坑的离子浓度特征进行了研究,结果表明:Ca2+、NO-3和SO42-是哈密庙尔沟平顶冰川雪坑雪层和积累区雪坑底部冰中的主要离子(尤其是Ca2+),其雪层中的主要阳离子关系可在底部冰中得以较好的反映,但雪层中各离子浓度与海拔的相关性不明显,可能与海拔的跨度较小和挖取的雪坑较疏有关;雪坑底部冰中的离子浓度与海拔间明显的相关性说明淋融作用随着海拔升高、气温降低而逐渐减弱。

Sensing ability of PSS/PANI self-assembled film with different doping/dedoping structure to DMMP and CEES was investigated. Results demonstrate that the gas sensitivity of PSS/PANI self-assembled film is affected by the size of dopant counterions. Gas sensitivity of self-assembled film increases with increasing size of dopant counterions. It is found that sensing ability of PSS/PANI self-assembled film to DMMP increases significantly by redoping/dedoping EB-PSS/PANI film with sarin acid that has similar structure with DMMP.
