【摘要】 冰川化学成分的研究对了解物质在大气圈、水圈、岩石圈中的循环及其相互作用是十分重要的。 1981年夏天为化学分析曾采集了降水、冰雪以及融水的90个样品。这些样品带至名古屋大学进行了F^-、CI^-、SO₄^2-、NO₃^- 和K⁺、Na⁺、Ca²⁺、Ms²⁺的测定。划分出五组:新雪、雪盖、冰川冰、污化层以及表面融水。计算出各组每种离子的平均浓度和均方差。给出了各组浓度变化的总趋势。污化层中阴离和阳离子的浓度较其它组高2至7倍。更多还原

【Abstract】 The stundy on chemical composition of glaciers is important to know the characteristics of the material circulation in the atmosphere, hydrosphere, lithosphere and the interaction between these sphere.Ninety samples of precipitation, snow, ice and melt water for chemical analysis were collected during the summer in 1981. These samples were brought to the laboratory in Nagoya University for the determination of F-, Cl-. SO42-, NO1- and K1. Na+. Ca2+, Mg2+. Samples arc classified into 5 groups, namely-New snow, snow cover, glacier ice, dirt band and surface melt water, The mean concentration and standard deviation of various chemical components in each group of samples are estimated. General tendency of the concemration among these groups are described. The concentration of each anion and cation in dirt band has 2-7 times higher value than it in other groups.更多还原
