| 摘 要： | 根据含化合物金属熔体结构的共存理论、相图和Fe－C系亚稳态化合物的有关热力学数据制定了Fe－Si－C熔体的作用浓度计算模型，计算结果符合实际，从而证明所推导的计算模型可以反映本熔体的结构实际．就碳而言，就碳而言，以饱和为标准态的碳作用浓度Nc′可以通过考虑纯物质到饱和标准态的转换系数Lc来求得．

| Abstract: | Based on the coexistence theory of metallic melts structure involving compound formation, plase diagrams and pertinent thermodynandc data of metastable compounds in Fe-C-system, a calculating model of mass action concentrations for Fe-Si-C melts has been formulated. Good agreement between calculated and measured values shows that the model can reflect the structural reality of given melts. As regarding to the mass action concentration of carbon at saturated condition Nc', it can be calculated by considering the transferrring coefficient from pure carbon to its saturated state Lc. |
