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