精确计算不同温度下液体导热系数的新方法

A new method for calculating the thermal conductivity of liquids at various temperatures with accuracy

根据液体微观结构的特点和热传导机理，发展了一种计算液体导热系数的新方法。对２７３种物质６２７１个数据点的计算结果表明，该方法在很宽的温度范围（熔点到沸点以上温度）内具有很高的准确度，平均误差仅０．２９２％，计算精度优于文献方法。

Based on the characteristics of microstructure of liquids and the mechanism of heat conduction, a new method was developed which can be used to calculate the thermal conductivity of liquids at various temperatures. The results of calculation show that this method has high accuracy in a wide range of temperatures(from melting point to above boiling point). The mean relative deviation was only 0.292% for 273 kinds of compounds with 6271 data points,and has an advantage over the existing methods.
