英文摘要：

This paper studies the diffusion of mechanical power air pollution, according to the characteristics of the diffusion of improved fuzzy comprehensive evaluation model. The fuzzy comprehensive evaluation method and the combination of mechanical exhaust pollution levels were evaluated. Through case studies, the results obtained are more consistent with the real results provide a theoretical basis for air pollution control.
