摘要
根据液体介电常数随温度的变化规律 ,发现介电常数ε- 1 /3与温度T之间存在着线性关系ε- 1 /3=B1 +B2 T对纯液体和液体混合物不同温度下介电常数的计算结果表明 ,计算值与实验值的一致性令人满意 ,平均误差0 79% .用两个数据点确定式中的两个常数 ,即可预测其它温度下的介电常数 ,对纯液体和液体混合物的预测结果表明 ,预测值接近实验值 ,平均误差 0 83 %
The quantitative relation between dielectric constant and temperature of liquid was studied in this paper.It was found out that a good linear was between the minus third power of dielectric constant and temperature,and so we can predict the dielectric constant of pure liquid and liquid mixture at different temperatures from two data points.The predicted results showed that the predicted values of dielectric constant are in good agreement with the experimental data,the mean relative deviation was 0.83% for 341 data points.
