摘要：
In the inhibition of the combustion of hydrogen-oxygen mixtures, the consumption of O2 by the inhibitor is only due to preliminary reactions between the inhibitor and active intermediates of H2 combustion. These reactions result in chain termination. The inhibiting effect of an admixture is determined by its chain-terminating capacity. The denial of the inhibiting effect by some authors is, in essence, the denial of the chain nature of combustion.
