摘要: Although the concept of a flame is clear to everyone, no completely satisfactory definition has been put forward. A results from an exothermic gaseous reaction, but not all such reactions sustain flames. temperature may vary between few hundred and over five thousand degrees, luminosity be due spectra species present in hot gases, or continuous radiation solid particles. flame, short, characteristics common with many other phenomena particular show characteristics. This large part complex nature which does correspond any one system capable terms equilibrium, rather open assembly systems.
