| Abstract: | Based on Mach-Zehnder optical interference model,a digital real-time holographic interferometric experimental system was set up.A new diffusion cell specially for measuring binary gas diffusion coefficient was designed and constructed.The experimental theory of measuring binary gas diffusion coefficient and the interference fringe processing method based on difference of object wave's phase was introduced in detail.On this base,the diffusion coefficients of H_2,CH_4 and O_2 in air at T=273.15 K and p = 0.1 ... |
