摘要 结合已有的实验结果,通过考虑活性剂特性和浓度对分子间引力和斥力的不同影响,建立了通用的分离压理论模型,并给出了自由能密度表达式。所建模型包含了活性剂浓度Γ、毛细力数C、指数(m,n),以及预置液膜厚度h∞等因素的影响,进一步完善了分离压模型的理论研究。 Combining with published experimental results,a general disjoining pressure model is established based on considering the different influence of surfactant concentration on intermolecular repulsive and attractive forces,and the expression of the free energy density is formulated in present paper.The present model includes the effects of surfactant concentration Γ,capillary number C,exponents index（m,n） and prewetted film thickness h∞,and provides an improved theoretical model for exploring the disjoining pressure.
