讨论了电子在弹性和非弹性碰撞状态下通过气体的传输，并显示了如何通过考虑速度图更简单地推导出 Smit 推导出的能量分布方程。本分析适用于氦、氖和氦-氖混合物，其中采用数值积分技术计算电子能量分布函数和输运系数，范围为3<或=E/p0<或=40 V cm-1 torr-1。将目前的结果与以前的理论计算和电子传输系数的实验测量进行比较，结果表明，以前的一些计算中涉及的近似可能会导致显着的错误。
The transport of electrons through gases in the regime of elastic and inelastic collisions is discussed and it is shown how the equation for the energy distribution derived by Smit follows more simply from consideration of the velocity diagram. The present analysis was applied to helium, neon and helium-neon mixtures where numerical integration techniques were employed to calculate electron energy distribution functions and transport coefficients in the range 3<or=E/p0<or=40 V cm-1 torr-1. The present results are compared with previous theoretical calculations and experimental measurements of electron transport coefficients and it is shown that approximations involved in some previous calculations can lead to significant errors.
