摘要
从群集统计理论出发,运用溶液表面热力学原理,推导出新的溶液表面张力方程.该方程形式简单,使用方便,参数具有直观的物理意义.通过235对各类物系的实验数据检验,表明本方程具有广泛的适用性和可靠性.
A new equation for calculating surface tension is deduced with group theory and surface thermodynamics of solution
The equation is simple in form and conveninent in use, and the parameters have obvious physical meaning. For a very dilute solution the equation can be simplified into
σo - σ = αc
The experimental data in the literature and empirical equations, such as Szyzkowski equation for the absorptive system of monomolecular film could be interpreted with the proposed equation. Correlation of the data for 235 binary system with this equation shows that this equation is more applicable and reliable.
