摘　　要：利用液闪技术测定了非离子表面活性剂在甲苯与水两相间的扩散系数和在临近界面处的两相分配系数。结合其他参数计算得出传质界面的界面稳定系数Marangoni数。在表面活性剂分子结构相似时 。The diffusion coefficient partition coefficients of nonionic surfactants of AP series were measured by liquid technique in this paper.Combined with others physical chemistry parameters,the critical volume of Marangoni number that relate to instability of interface was calculated.The relationship which between the instability of interface and the physical chemistry parameters was discussed.
