通过建立数学模型推导出烟雾浓度与其影响因素的数学关系式，并分析出烟花爆竹爆炸后在扩散的过程中不同单一因素与空气中颗粒物浓度的关系。%Through the establishment of mathematical model of smoke concentration and influence factors of the mathematical relationship, the re-lationship between concentration of particles of different single factor and in the air and the analysis of the process of fireworks and firecrackers ex-ploded in the air in the diffusion.
