中文摘要：

用ZBY-1全自动表面张力仪测定了288～333K温度范围内,二乙醇胺（Diethanolamine,DEA）、N-甲基二乙醇胺（N-methyldiethanolamine,MDEA）及其混合水溶液的表面张力,并分析了混合溶液的表面熵和表面焓等热力学性质与醇胺浓度的关系.

英文摘要：

In this work, the surface tensions of pure diethanolamine （DEA）, pure N-methyldiethanolamine （MDEA）, and DEA-MDEA-water mixtures from 288 to 333 K were measured by using an automatic surface tension-meter. The thermodynamic properties like surface enthalpy and surface entropy of DEA-MDEA water mixtures were determined and their concentration dependence was analyzed.
