- 中文摘要: A rapid determination of the diffusion coefficients of some gasvapor binary systems was studied with a method similar to the operation of gas chromatographic techniques. The diffusion coefficients of some hydrocarbons and alcohols in hydrogen atmosphere were determined. Then, detailed comparisons of these data with the available experimental values obtained by other methods and with the theoretical values calculated from the equations of Gillil- and , Arnold, Hirschfeder, Slattery, Othmer, and Giddings respectively were discussed. The diffusion coefficients at various tem- peratures and flow rates of the carier gas were studied and their correlations to the different types of tubes were also discussed. The temperature power dependences of their diffusion coefficients were found experimentally for several gas-vapor binary systems.
