摘要
用等活度法和解病态方程组的其轭斜量法求解厂1200°C时铜基溶液中Pb与Ce，Y的情度相互作用系数，并计算得到Ce，Y的脱氧常数和Ce2O3。
Using the iso-activity method and the conjugate gradient method for solvingill-conditioned equations, the activity interaction coefficients between Pb and Ce, Y were detetalned in the Cubased solutions at 1200℃. The equilibrium constant of deoxidation of Ce,Y and the standard Gibbs free energy of formation of Ce2O3, Y2O3 in the liquid Cu were alsoobtained.
