By using the generalized Boltzmann equation of transport and the first‐order approximation of Chapman‐Enskog expansion on the κ‐distribution function, we study the thermal conductivity and Dufour effect in the weakly ionized and magnetized plasma. We show that the thermal conductivity and Dufour coefficient in the κ‐distributed plasma are significantly different from those in the Maxwell‐distributed plasma, and the transverse thermal conductivity and Dufour coefficient in the κ‐distributed plasma are generally greater than those in the Maxwell‐distributed plasma, and the Righi‐Leduc coefficient and Hall Dufour coefficient in the κ‐distributed plasma are also generally greater than those in the Maxwell‐distributed plasma.

在弱电离，磁化和κ分布等离子体中的热导率和Dufour效应

通过使用广义的Boltzmann输运方程和Chapman-Enskog展开对κ分布函数的一阶近似，我们研究了弱电离和磁化等离子体中的热导率和Dufour效应。我们表明，在热导率和Dufour的系数κ -分布式等离子体不同于麦克斯韦分布的等离子体中显著不同，并且在横向热导率和Dufour的系数κ -分布式等离子体通常比那些在麦克斯韦更大分布等离子体中，κ分布等离子体中的Righi-Leduc系数和Hall Dufour系数通常也比Maxwell分布等离子体中的高。
