摘要: 借助于引入θ參數所得到的組元的活度系數與溫度間的新關系式,導出了由二元簡單共晶的相圖計算組元活度的修正式。應用本文的新公式計算了1200K下Cu-Bi二元系中Cu-Bi的活度,結果表明經修正后的公式與實測數據吻合。Abstract: New formulae for calculating from simple eutectic binary phase diagram are presented, by introducing a parameter θ and leading to a new expression of activity coefficient with temperature. Using these new formulae, activities of Cu and Bi in Cu-Bi binary systemat
