摘要：

The surface entropies of liquid transition and noble metals Fe, Co, Ni, Cu, and Ag have been investigated. Surface entropy expression involving hard-sphere (HS) interaction in closed form is used. Since the HS diameter depends on metallic properties and temperature, the temperature dependent effective HS diameter is determined from a well-known perturbation theory, linearized Weeks-Chandler-Andersen (LWCA) and integral equation theory, variational modified hypernetted chain (VMHNC). Theoretical calculations are compared with the available experimental data, and found good agreement for some concerned systems. (C) 2011 Elsevier B.V. All rights reserved.
