给出了空气、空气与氩气、空气与氮气、空气与氧气的混合物在高温下的粘度、导热系数和电导率的计算值。此外，结合普通，压力和热扩散系数的气体混合物。计算是在300 ~ 30000 K温度范围内对大气压等离子体进行的，并考虑了局域热力学平衡。空气等离子体的结果进行了比较与发表的理论和实验研究。与其他理论研究发现显着的差异，这些是由于在计算运输系数中使用的碰撞积分的差异。这里使用的碰撞积分的数量是显着更准确的值比以前使用的，导致更可靠的值的传输系数。
Calculated values of the viscosity, thermal conductivity and electrical conductivity of air and mixtures of air and argon, air and nitrogen, and air and oxygen at high temperatures are presented. In addition, combined ordinary, pressure, and thermal diffusion coefficients are given for the gas mixtures. The calculations, which assione local thermodynamic equilibrium, are performed for atmospheric pressure plasmas in the temperature range from 300 to 30,000 K. The results for air plasmas are compared with those of published theoretical and experimental studies. Significant discrepancies are found with the other theoretical studies; these are attributed to differences in the collision integrals used in calculating the transport coefficients. A number of the collision integrals used here are significantly more accurate than values used previously, resulting in more reliable values of the transport coefficients.
