用改进的Barrer法测定了溶解在水和海水中的重要气体示踪剂的扩散系数D。测量包括在5 - 35°C温度范围内溶解在蒸馏水中的He、Ne、Kr、H2、CH 4和CO2气体，以及在相同温度范围内溶解在海水中的He和H2气体。最大系统误差估计远低于5%。13 CO2/12 CO2和3 He/4 He的扩散系数ε D分别为（−0.87 ± 0.05）‰和（15 ± 3）%。
The diffusion coefficientsDof important gas tracers dissolved in water and seawater were measured with a modified Barrer method. The measurements include the gases He, Ne, Kr, Xe, H2, CH4, and CO2dissolved in distilled water in the temperature range from 5 to 35°C, and He and H2dissolved in seawater in the same temperature range. The maximum systematic error is estimated to be well below 5%. The isotopic fractionation in the diffusion coefficient, ∈D, was determined to be (−0.87 ± 0.05)‰ for13CO2/12CO2and (15 ± 3)% for3He/4He.
