摘　　要：为探求抑制连通容器内预混气体爆炸的方法,选取蜂窝状铝合金作为抑爆材料,对连通容器内气体密闭爆炸与泄爆进行试验研究。考虑管道内是否填充抑爆材料的情况,考察不同条件下连通容器内气体密闭爆炸及泄爆的压力变化规律。结果表明:加入抑爆材料后,不论连通容器密闭爆炸还是泄爆,2球容器的爆炸强度均低于无抑爆材料的情况;特别是传爆容器,相比于无抑爆材料的情况,其压力峰值分别下降84.4%和99.9%。In order to explore methods of inhibiting the gas explosion in linked vessels, experiments about closed and vented explosion were conducted by using pieces of honeycombed aluminum alloy as the inhibitor. The results showed that peak pressure in linked vessels with explosion suppression material in duct was lower than that without explosion suppression material. And peak pressure in secondary vessel decreased more obviously, by 84.4% and 99.9% respectively.
