On the basis of the embedded atom model reflecting many body interactions among atoms and the effective pair potential, structures and microdynamic behavior of liquid transition me-tal Pd and Pt have been investigated by means of molecular dynamics simulation with compu-ter. Pair distribution function, mean square displacement, self-diffusion coefficients and nor-malization velocity self-correlation function have been calculated, and the influence of many body interactions on these physical quantities have been discussed. Results show that the inf-luence of many body interactions on the pair distribution function is small, but this influence on mean square displacement, self-diffusive coeffcients and normalization wlocity self-correla-tion function is cons derable.
