摘要：

Physicochemical measurements by gas chromatography are reviewed, and the carrier gas flow-rate perturbation is introduced as the stopped-flow and the reversed-flow techniques. The general principles of the latter are presented, and then the latest theoretical developments and applications for measurement of rate coefficients and distribution constants are given. These include gas diffusion coefficients, obstructive factors and external porosities in solid beds, diffusion coefficients of gases in liquids,interfacial gas-liquid resistances to mass transfer, and the simultaneous determination of adsorption, desorption and reaction rate constants of gases on solids.
