摘要：
The molecular dynamics calculations of diffusion coefficients in binary Lennard-Jones liquids have been carried out. The change of diffusion mechanism has been observed with transition from dense gas to liquid. The diffusion mechanism in liquids isn't connected with jumping motion of molecules. A good agreement between our results and the experimental data for krypton diffusion in liquid argon has been obtained.
