本文研究了磁场作用下计算非平衡部分电离Ar输运性质的Chapman-Enskog方法的收敛性质，着重讨论了不同碰撞积分的作用。特别是，电子-Ar截面的拉姆绍尔极小值在低温下影响Chapman-Enskog方法的收敛，而库仑碰撞在较高温度下影响结果。外加磁场的存在缓解了受磁场影响的分量的缓慢收敛。
Convergence properties of the Chapman-Enskog method in the presence of a magnetic field for the calculation of the transport properties of nonequilibrium partially ionized argon have been studied emphasizing the role of the different collision integrals. In particular, the Ramsauer minimum of electron-argon cross sections affects the convergence of the Chapman-Enskog method at low temperature, while Coulomb collisions affect the results at higher temperatures. The presence of an applied magnetic field mitigates the slow convergence for the components affected by the field.
