以统计力学方法、晶格模型为基础，提出研究理想溶液在能量非均匀固体表面上吸附的新方法，得到吸附相活度系数表达式．模型推导过程中，直接考虑了固体表面能量分布不均匀性的影响．计算吸附等温线时，不必再求解积分方程，并可由二元理想溶液在固体表面的吸附平衡数据做多组无吸附体系平衡预测．对于几个二元理想溶液在固体表面的吸附体系，进行了理论等温线与实验数据的比较，结果令人满意．
Based on statistical mechanics and lattice model, a new method to study the adsorption of ideal solution on the surface of energy non-uniform solid was proposed, and the expression of activity coefficient of adsorbed phase was obtained. In the process of model derivation, the influence of inhomogeneity of energy distribution on solid surface is considered directly. When calculating the adsorption isotherm, it is no longer necessary to solve the integral equation, and the equilibrium prediction of multiple adsorption-free systems can be done from the adsorption equilibrium data of the binary ideal solution on the solid surface. For the adsorption system of several binary ideal solutions on the solid surface, the theoretical isotherms and experimental data were compared and the results were satisfactory.
