摘　　要：自行设计了管内低浓度瓦斯爆燃实验系统,通过一系列实验研究了低浓度瓦斯爆燃特性,分析了不同初始压力、初始温度对瓦斯爆燃特性的影响。实验结果表明:火焰传播速度随着初始压力和初始温度的增大而增大,峰值超压随着初始压力和初始温度的增大而增大。A deflagration experiment system with low concentration gas in pipeline was self designed.Base on the experiment platform,a series of the experiments was applied to study the low concentration gas deflagration features,the different initial pressure and the initial temperature affected to the gas deflagration features.The experiment results showed that the flame travel speed would be increased with the initial pressure increased and the peak overpressure would be increased with the initial pressure increased.The flame travel speed would be increased with the initial temperature increased and the peak overpressure would be increased with the initial temperature increased.
