摘要：

It is found that additives containing i-C4H8, CO2, CF3H, and CF4 effectively inhibit the ignition and combustion of air-methane mixtures of any composition at atmospheric pressure, evidence of the branched-chain character of methane combustion. The reason for the great distinction between the efficiency of inhibiting methane and hydrogen combustion by trifluoromethane is found. The synergism in the joint effect of the abovementioned additives is revealed and taken advantage of. It is shown that the effect is inherent to the branched-chain mechanism.
