摘　　要：根据层燃炉非阻力型冒正压的特点,发展了“微爆燃”理论,提出涡脱落诱导声共振的燃烧振荡机理,并运用该机理对非阻力型正压发生的条件进行了分析。According to the features of non- resistance puff, the “ slight deflagration” mechanism is extended. The mechanism of combustion oscillation including acoustic resonance induced by vortex shedding is advanced. The conditions of the occurrence of non - resistance puff are analyzed with the mechanism as well.
