摘要: 全面描述和处理了截面数值计算中所遇到的临界现象、振荡现象和积分限的截断等问题。根据用我们的方法求出的原子间相互作用势,计算了惰性气体的截面、碰撞积分和输运系数。对输运系数的计算结果与实验值进行了比较。

Abstract: The critical and oscillating appearances ane the break of the integral limit which are encountered in the numeral calculation of the cross section are described and treated overally. The cross sections, collision integrals, and transport coefficients of noble-gases are calculated, according to the interactions of noblegas atoms by our method. The transport coefficients are compared with the experimental
