饱和液体介电常数的关联

Correlation of the Dielectric Constant of Saturated Liquids

根据液体介电常数ε随温度的变化规律 ,发现lnε与温度 (1-Tr) 1 / 2 之间存在线性关系 ,对饱和液体介电常数的拟合结果表明 ,计算值与实验值的一致性令人满意 ,平均误差 0 .47%。应用两个数据点确定式中的两个常数后 ,即可对介电常数进行预测。结果表明 ,饱和液体介电常数计算值接近实验值 ,平均误差 0 .5 4%。

The quantitative relation between dielectric constant and temperature of saturated liquid was developed, and a method was proposed to calculate the dielectric constant of saturated liquid at different temperature from two data points. The results show that the calculated values of dielectric constant are in good agreement with the experimental data, the mean relative was 0.54% for 327 data points.
