【Abstract】 The contents of this review cover mainly the liquid diffusion of binary systems of nonelectrolytes. It consists of four parts: 1. the phenomenological expression of liquid diffusion process; 2. the liquid diffusion theories——hydrodynamic theories, absolute rate theory and others; 3. the prediction correlations at infinite dilution, with concentration and with temperature; 4. the experimental methods of determination—the diaphragm method, the optical interferometric method, the radioactive sotope method, the nuclear magnetic resonance method, the disperion method and other methods.更多还原
