英文摘要	Snow and firn samples recovered from two snow pits (2.5 and 4.5 m deep) and one 50-m firn core along the route of the 1996/1997 Chinese First Antarctic Inland Traverse Expedition in Princess Elizabeth Land, East Antarctica, have been measured for chemical composition and oxygen isotope ratio, in the two snow pits, the variations of NO3- are partly in phase with that of delta(18)O, while the variations of Cl- and Na+ are in inverse phase with that of delta(18)O. The variations of Cl-, Na+, NO3- and delta(18)O show obvious seasonal variations and annual stratagraphy. However, with the depth increasing, the seasonal Variations of delta(18)O are gradually smoothed below 3 m (corresponding to about 10-year mass accumulation) in depth while the seasonal variations of Cl-, Na+ and NO3 - are kept fairly well in the whole profile of the 50-m firn core (corresponding to about 250-year mass accumulation). The results provide a useful tool for dating the snow stratum in this region. On the contrary, no obvious seasonal variations of Ca2+ are found in the profiles.
