| Abstract: | A real-timeholographic interferometer is used to measure the diffusivities of glycine aqueors solution.The diffusion coefficiente of sucrose aqurous solution are measured at temperature 250C to verify the accuracy and reliability of the insrument,and good results are obtained (the total relative error was 0.84%).Furthermore,the diffusion coefficients or glycine aqueous solution at different concentrations are meadured by means of the instrument,the diffusivities and average values of glycine aqueous solution at different positions foe each concentration are obtained respectively.At lasr,the determined results are analyzed and discussed. |
