摘要：

The molecular dynamics of the two supercritical fluids most applied in industry and some of their mixtures are characterized by their self-diffusion coefficients Di, measured by high pressure high resolution nuclear magnetic resonance with the strengthened glass cell technique. The technical details of the apparatus will be given. The fluids studied are carbon dioxide and ammonia. For CO2, mixtures with C6H6, H2, CH3COOH and CH3OH were investigated. The NH3 mixtures include C6H6, (CH3)3N, CH3CN and CH3OH.
