本文从理论和数值计算两方面研究了在任意约化电场强度E/n 0下，Blanc定律在混合气体中电子和离子漂移速度计算中的应用。修正的Blanc定律，包括非弹性碰撞的影响。此外，我们还推导出了Chiflikyan在一般情况下提出的离子和电子的共同平均能量程序。修正后的commonE/n 0和共同的平均能量程序提供了极好的结果，即使是在moderateE/n 0的应用布兰克定律被认为是不可能的电子。在具有负微分电导率（NDC）的两种气体的混合物中，即使两种纯气体都不显示NDC，Blanc定律程序也能够给出很好的预测。
Application of Blanc’s law for drift velocities of electrons and ions in gas mixtures at arbitrary reduced electric field strengthsE/n0was studied theoretically and by numerical examples. Corrections for Blanc’s law that include effects of inelastic collisions were derived. In addition we have derived the common mean energy procedure that was proposed by Chiflikyan in a general case both for ions and electrons. Both corrected commonE/n0and common mean energy procedures provide excellent results even for electrons at moderateE/n0where application of Blanc’s law was regarded as impossible. In mixtures of two gases that have negative differential conductivity (NDC) even when neither of the two pure gases show NDC the Blanc’s law procedure was able to give excellent predictions.
