Abstract: A new theory of thermal conduction, the reaction rate theory has been established. By using the model of statistical thermodynamics and the idea of local composition, a new equation of thermal conductivity was given in the form ofThis equation was applied to 87 binary systems for correlation and 5 ternary systems for prediction. The results showed that the equation was of good applicability and reliability.

摘要： 本文从传质反应速率理论的基本思想出发,建立了一个新的传热理论——传热反应速率理论。结合统计热力学模型,引进局部组成概念,导出了一个新的导热系数方程。对于n元液体混合物,该方程可表示为: λ=(2πRT~3 multiply from i=1 to n M_ix_1)(1/2)·〔(s/2)sum from i=1 to n Q_ix_1U_11-RT sum from i=1 to n θ_i lnτ_(jt)〕~2·exp〔sum from i=1 to n q_in_ix_i sum from j=1 to nθ_(ji)lnτ_(ji)-a/2RT sum from i=1 to n q_jn_ix_iU_(ji)〕该方程应用于87个二元体系的关联和16个多元体系的推算结果表明该方程是可行的和可靠的,计算精度是令人满意的。
