抄録

The correlation entropy theory by Baranyai and Evans produces non-negligible entropy contributions arising from the four-body and even higher order terms of correlations. If we express this as S^(x), the estimated value of S^(x) is 0.6 (±0.1) Nk_B near the melting point when the structure factor of a liquid metal is of hard-sphere form (I. Yokoyama and S. Tsuchiya: Mater. Trans. 43 (2002) 67–72.). The purpose of the present paper is to propose a way for avoiding the large positive value of S^(x) and to show the recalculated results of the total entropy, diffusion coefficient, viscosity coefficient and surface tension of the liquid metals studied in the previous paper using the proposed pair and triplet correlation entropies definitions.
