| 摘 要： | During the 22nd Chinese Antarctic Research Expedition(CHINARE-22,2005/06),the atmospheric gas samples near the surface were taken on the Millor Peninsula and adjacent areas,east Antarctica,using Tedlar gas bags.The methane(CH4) concentration and δ13C-CH4 in those samples were analyzed in the laboratory.The average value of atmospheric CH4 concentration on this peninsula was(1.87±0.12)×10-6,slightly higher than the global average CH4 concentration.The summertime variation of CH4 concentrations showed a large...
