【摘 要】The deuterium and 18O in various Antarctic snow samples including the surface snow, which collected along the track from Station Zhongshan to Dome A, overlying snow on sea-ice, fresh snow and lake water nearby Station Zhongshan, were measured. The results indicate that δD and δ18O in the surface snow of Antarctic inland were negatively correlated with the latitude and the sea-level elevation respectively. In the snow core from the overlying snow on sea-ice, the depth distributions of δD and δ18O appeared the feature of variation with the seasons. The relationship between δD and δ18O in various snow samples were studied. The relation equation for both δD and δ18O for fresh snow was most close to the Craig’s meteoric water line (MWL) and the equation for lake water far from MWL.%测定了南极中山站至Dome A沿线表层雪、中山站附近海冰上覆雪、新降雪和中山站附近湖水的D和18O，对内陆雪δD和δ18O随纬度和海拔高度的变化、海冰上覆雪δD和δ18O随深度的变化，各种雪中δD和δ18O之间的相关性进行了研究. 【总页数】5页(P664-668)
