摘要：

Volume-mean correction factors are used in the dusty-gas equation to account for heteroporosity effects on isobaric and nonisobaric mass transfer in general porous media. Using conventional information on pore-size distribution, the modified equation maintains reliance on the original dusty-gas constants for characterizing the porous structure. The modified equation was tested with experimental data for a binary helium-nitrogen system in macroporous α-alumina and microporous γ-alumina. © 1979.
