正链烷烃的表面张力与碳原子数之间的定量关系

Quantitative Relation between the Surface Tension and the Number of Carbon Atoms of Normal Paraffin Hydrocarbons

不同温度下，正链烷烃的表面张力与碳原子数间定量关系可表示为：由该式计算的结果与文献值吻合，并分析讨论了式中各系数的物理意义．

The quantitative relation between the surface tension and the number of carbon atoms of normal paraffin hydrocarbons at different temperature are studied systematically in this paper. The result can be expressed as follows: Here σT(n) is surface tension, n is the number of carbon atoms of paraffin hydrocarbons,Tis the temperature. The calculated results by the formula are in good agreement with the literature values.
