Heat uniformly, sweeping the flame from the fitting to the tube until the flux on the fitting becomes quiet.

加热要均匀，将火焰从管件扫到管道直到管件上的焊剂变得平静为止。

The results indicate that the effect of water mist suppression gas explosion flame is related to mist flux, mist momentum and mist drop diameter.

结果表明：水雾对气体爆炸火焰的抑制效果与雾通量、雾动量和雾滴粒径有关。

Some key fire parameters, such as heat release rate, heat flux, room temperatures etc, were also performed and compared with the flame spread. The relationships among these parameters were analyzed.

通过测量材料表面的温度来研究火蔓延的情况，同时还将火蔓延与火灾过程中的重要参数如热释放速率、热流密度和室内温度等进行了比较，分析了相互之间的关系。
