| 摘 要： | 运用质谱技术 ,测定了南极中山站至 Dome A剖面 1 998/1 999年度表面雪样氧同位素组成。结果表明 ,表面雪样氧同位素组成变化范围相当大 (- 2 2 .5 1‰ - - 5 0 .6 7‰ ) ,且具有随距中山站距离逐渐增大、海拔高度逐渐增加而逐渐减小的趋势。线性回归分析显示表面雪样氧同位素组成与距中山站距离、海拔高度和纬度存在着很好的相关性 ,这实际上反映出稳定同位素组成和温度之间的密切联系

| Abstract: | Oxygen isotope composition of surface snow sampled in the austral summer of 1998/1999 along the traverse route from Zhongshan Station to Dome A, Antarctica is measured with the conventional mass spectrometer technique. The results of measurement show that oxygen isotope composition of surface snow varies in a wide range from -22.51‰ to -50.67‰, and has a tendency that isotopic values gradually decrease with the increases of distance from Zhongshan Station and altitude. The linear regression analyses indicate that there exists good correlation between oxygen isotope composition of surface snow and distance from Zhongshan Station, altitude or latitude, which actually reflects the close relation between stable isotope composition and temperature. |
