| 摘 要： | 根据相图、质量作用定律和金属熔体结构的共存理论制定了Mg-Al,Sr-Al和Ba-Al熔体的作用浓度计算模型并求得了相关的热力学参数，计算结果符合实际，证明所制定的模型和确定的热力学参数可以反映相应熔体的结构特点，但将相应文献的热力学参数代入同样熔体则未取得符合实际的结果，原因可能与文献中的热力学参数不符合液态下金属熔体内部化学反应的实际有关。

| Abstract: | Based on the phase diagrams and the mass action law in combination with the coexistence theory of metallic melts structure,calculating models of mass action concentrations for Mg Al,Sr Al and Ba Al were formulated and their thermodynamic parameters were determined.Calculated results agree with practice,showing that the models formulated and the thermodynamic parameters determined can reflect the structural characteristics of relevant melts.However,application of thermodynamic parameters from literature sources to the same melts did not give agreeable results with practice,which might arise from unconformity of these thermodynamic parameters to the chemical reaction conditions in liquid metallic melts. |
