Conventional combustion can only exist within well-defined fuel to air ratios, known as the flammabilitylimits.
常规燃烧只存在于理想的燃料空气比中，叫作可燃性界限。

The analysis of the flammabilitylimits of cylindrical flames is made. It is demonstrated that heat loss effects greatly the flammability.
并在此基础上对圆柱火焰的可燃极限进行了研究，结果表明热损失对可燃极限产生很大的影响。

The experimental results showed that the hydrogen concentration for the flammabilitylimits decrease with the velocity of gas flow in the annular microchamber.
