STRUCTURES AND MICRODYNAMIC BEHAVIOR OF LIQUID TRANSITION METAL Pd AND Pt
液态过渡金属Pd和Pt的结构与微观动力学行为

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.
