| 中文摘要: |
| 本文研究了不同含水量的燃料床在不同风速下阴燃的传播速度，测量了不同含水量的燃料由阴燃转捩成明火的临界风速。实验结果表明燃料床的不同高度层阴燃发展传播的速度不同，正向阴燃和逆向阴燃的规律也不相同。阴燃转捩成明火的临界风速不但与燃料情况（如含水量等）有关，还与风速增加的规律有关。 |
| 英文摘要: |
| he propagation rate of smoldering in horizontal fuel layers with varied water con-tent is measured in varied air flow velocity.Tair flow velocity for the transition toflaming(the critical velocity ) of the fuel layers with varied water content is also mea-sured.The results show that the propagation rate through the fuel is dependent on thehieght of the layer and the propagation character of forward and reverse smolder is dif-ferent.The results also show that the critical air flow velocity is in connection not onlywith the condition of the fuel (such as the water content)but also with the increasingrate of th air flow velocity. |
