摘要：
A model is developed for dynamic supercritical-fluid extraction, which includes the effects of both solvation by the fluid and diffusion out of the matrix. The model is consistent with many of the features of available experimental evidence. It predicts the forms of both typical 'pressure threshold' and kinetic curves for dynamic extraction.
