| 摘 要： | 在利用Onsager模型推导液体表面张力与内压间的关系时, 文献[4]忽视了曲率对表面张力的影响, 致使计算值与实验值的偏差较大。本文对此作了修正, 建立了一个新的关系式, 用实验数据检验表明, 它能满意地适用于广阔温度范围内的各种液体。

| Abstract: | An expression developed by Rosseinsky for relating surface tension and internal pressure is modified by considering the effect of curvature on surface tension of liqs. A new relation between internal pressure and superficial properties of liqs. has been obtained. The agreement between calculated results and the experimental data indicates that this relation is satisfactorily applicable to various liqs. in a wide temperature range.7 |
