摘要：
A pseudopotential method was applied to calculate the composition dependence of the viscosity in liquid alloys of Cu-Al, Cu-Sn, Cu-Sb, Cu-Pb and Cu-Bi. A new approach is introduced to solve the problem of integration over diverging integrands. In accordance with the experimental findings, the deviations of I he viscosities from the additive law were found to be negative for all systems under investigation. A semi-empirical consideration based on fundamental physical quantities combined with the enthalpy of mixing as measure of the interactions between the constituent atoms was included in the discussion.
