摘要： 采用稀溶液模型建立了微分溶解焓与标准溶解吉布斯自由能的互算方法，并以铁液和镍液的标准溶解吉布斯自由能与微分溶解焓热力学数据验证，根据铝熔体中部分金属元素微分溶解焓计算了铝熔体中金属元素的标准溶解吉布斯自由能与温度关系式，为缺乏标准溶解吉布斯自由能热力学数据的金属熔体反应热力学计算提供了基础.

Abstract: A method of mutual calculation between standard dissolved Gibbs free energy and differential dissolution enthalpy based on a model of dilute solution was proposed. The validation of the mutual calculation method was confirmed according to the standard dissolved Gibbs free energy and differential dissolution enthalpy in liquid iron and liquid nickel. The relationship between the standard dissolved Gibbs free energy and temperature was established based on differential dissolution enthalpy in liquid aluminum. The method of mutual calculation provided a basis for the thermodynamic calculation of chemical reaction in liquid metal in which the thermodynamic data such as standard dissolved Gibbs free energy was lacked.

Key words: dilute solution, standard dissolved Gibbs free energy, differential enthalpy of solution
