一、引言 在森林火灾和城市建筑火灾中,木材作为一种主要可燃物,对于火灾的发生及发展具有重要的影响。其燃烧的特性,尤其是其燃烧的火焰及火焰传播的规律,往往决定了火灾发展的方向,并左右着局部火场的燃烧状况。因此,弄清木材燃烧的火焰传播的规律,已成为揭示森林火灾及城市建筑火灾发展规律的关键。 I. INTRODUCTION In forest fires and urban building fires, wood as a major combustible material has an important impact on the occurrence and development of fires. Its burning characteristics, especially the burning flame and the law of flame propagation, often determine the direction of the development of the fire and control the burning situation of the local fire. Therefore, to understand the law of flame propagation in wood combustion has become the key to reveal the law of forest fire and urban construction fire.
