摘　　要：本文采用溶解平衡的方法测定了碳在不同含量的Mn-Fe,Mn-Si合金中及不同温度下的溶解度,用同一活度法推算出1400℃及1500℃时的e_C^(Si),e_C^(Fe)值,用Wagner方程推算出了1400℃与1500℃时的lnγ_C~°,ε_C^C,△_C~°值。The solubility of carbon in Mn melts with different contents of Si and Fe at 1400℃ and 1500℃ was measured. Using the same activity method, the activity interaction coefficients ec51 and ecfeat 1400℃ and 1500℃ were determined with the experimental data. Mean while, the values of In γc0, εcc and △Gc0 at 1400℃ and 1500℃ were evaluated by Wagner's formula.
