The research result shows that the wall roughness has great effects on flametransmission in gas explosion.
研究结果表明，壁面粗糙度对瓦斯爆炸过程的影响很大，相比光滑管道，粗糙管的火焰速度大幅度提高；

When the tube is biforked, the additional turbulent flow will be produced, which will improve the flametransmission speed in gas explosion.
管道分叉时，产生附加湍流，使瓦斯爆炸过程中火焰的传播速度迅速提高。

On the basis of experimental study of the gas explosion flametransmission rule, the influence of branch tube on the flame in gas explosion was studied.
