摘　　要：碳黑对人类健康和环境辐射平衡有重要的影响。火焰中的碳黑,可以增强辐射换热效果,碳黑也影响氮氧化物的生成和排放。当煤不完全燃烧时,煤的挥发分在高温时发生二级反应,形成碳黑。介绍了研究碳黑的3种模型和3种实验方法。The presence of soot particles in air does great harm to people＇s health, and affects radiation equilibrium in nature environment. The soot is able to enhance radiation heat transfer effects in flames, because it＇s large total surface areal moreover, it affects the products and emissions of nitrogen oxides. The soot is the product of incomplete combustion of coal, and usually formed when the volatile matter of coal undergo secondary reactions. Three kinds of models and experimental methods have been introduced.
