摘要：

The extent to which simple diffusion may account for transport of CO2 in the unsaturated zone is investigated. The diffusion equation is solved with a periodic but otherwise arbitrary boundary condition below the root zone and a condition of reflection at the water table. The model is in good agreement with measurements by Reardon et al. and suggests that diffusion is an important process in such cases.
