摘要
文中根据作者建立的氩模型,从理论上阐明气体输运现象可用统一的数学方程描述,提出“气体不平衡状态方程”,进而将其移植应用于液体,提出液体导热率的半理论方程,经用极性与非极性等不同结构类型的液体纯质418个实验数据验证,平均误差1.7％,显著优于文献中各式。有重大的理论意义与实际应用价值。
According to the differential equation for a model of argon gas an equation for nonequiliblium state of gases was derived that could be extended to the liquid by which a thermal conductivity equation of normaal liquid was proposed as follows: λ_2=K_2[(T+140)/T^(14·7)]~n This equation can be applicd to both polar and nonpolar liquids. The average error from 418 experimental values is 1.7％ based on 102 organic and inorganic compounds. It is far better than all other methods in published literature.
