Abstract: The activity coefficients of a solute at infinite dilution,l_γⁿ,and interaction parameters, ε_nⁱ liquid Cu at 1 473 K are calculated by models.The calculation results show that the calculatedvalues are in accordance with the exl)erimental data on the whole.The ratios of same sign to l_γⁿ and ε_nⁱ reach 85% and 87.5% respectively.The main factors that affect l_γⁿ and ε_nⁱ are the electron density,n_ws,electronegativity,and molar volume I’ of solute i and solvent Cu.
