摘　　要：根据1986年11月32站和12站2个连续站的观测资料,计算溶解氧和二氧化碳在海气界面的交换速率。 调查海域溶解氧海气交换平均活塞速度0.378m/h,平均边界层厚度为30μm。忽略气体-溶剂反应对交换速率的影响,把由氧求得的边界层厚度应用于CO_2海气界面交换计算,求得CO_2的活塞速度为0.22m/h。We have calculated the exchange rate of the dissolved oxygen according to data obtained at 2 continually observed stations. Station 32 and 12 in November, 1986. By the following equation we acquired the exchange coefficient and thickness of the boundary layer.For detailed conclusion, see table I.Average piston speed of the dissolved oxygen exchange between water and air is 0.378 m/h, and average thickness of the boundary layer is 30μm in the water area observed. By neglecting the effect of gas-solvent reaction on the exchange rate and applying the boundary layer thickness computed by oxygen exchange into the calculation of C(02) exchange at the air-sea interface, we come to the conclusion that piston speed is 0.22m/h. The exchange rate of O2 and C(02) in the area observed is listed in Table Ⅲ .
