| 摘 要： | 在实验的基础上，研究了瓦斯爆炸过程中火焰传播规律及其加速机理．研究结果表明，障碍物对瓦斯爆炸过程中火焰传播规律具有重要影响．当有障碍物存在时，瓦斯爆炸过程中火焰的传播速度将迅速提高．在沿火焰传播的通道上设置障碍物，对气相火焰具有加速作用，这种加速作用的机理可归功于障碍物诱导的湍流区对燃烧过程的正反馈．

| Abstract: | The flame transmission and its accelerating mechanism in gas explosion are studied on the basis of experiment. The result shows that the barrier is very important to the transmission of flame in gas explosion. When there are barriers, the speed of transmission would be very fast. The flame would be accelerated when there are barriers on the road of flame transmission. The accelerating mechanism can be attributed to positive feedback of torrent, which is induced by barriers in combustion of gas explosion. |
