对多元爆炸性混合气体爆炸的阻尼效应,进行了比较系统的研究,实验表明:"惰性气体"N2, CO2与水蒸汽对多元混合气体支链爆炸具有一定的抑制作用;甲烷与石油液化气对含H2易爆混合气体支链爆炸具有明显的阻尼效应.这对指导支链燃烧与支链爆炸的实践,关于工业尾气与废气的安全回收,有关爆炸性混合气体的置换技术的改进,以及工业与矿井混合气体爆炸事故的预防,具有重要的现实意义与理论价值.

This work has systematically studied the damping effect of some other gases on the branch chain explosion of polybasic explosive mixture gas of H2, CO and CH4. The experimental results show that inert N2 gas, CO2 and water steam possess some inhibition effects on the branch chain explosion, while methane and petroleum liquid gas take on clear damping effects on the branch chain explosion of H2-containing explosive mixture gas. The results of the experiment will be of great significance in directing the practice of branch chain burning and branch chain explosion, the reclaiming and reusing of the related industrial tail gas and waste gas safely, the improvement of the transforming technology of explosive mixture gas, and preventing the explosion of explosive mixture gas in related industries and mines.

Key words: branched-chain explosion, concentration explosive limit, damping effect, free radical
