基于碳颗粒污染分析的PM2.5成因分析及其模型建立

In recent years, haze problem is serious in central and eastern regions of China. It is very important to comprehensively understand the haze phenomenon in the central and eastern part of China by analyzing the mechanism of PM2.5 from the perspective of physical process and establishing the mathematical model of PM2.5 microparticle forming physical process. In this paper, the mathematical model of TC-PM2.5 causal relationship is proposed by the cause of PM2.5 physical formation process. The strong correlation between Tc and PM2.5 concentration has been confirmed by PM2.5 content and the impact of the factors of the scatter plot. By comparing with the results of multiple linear regression models, it is found that the mathematical model of PM2.5 is better. The causal relationship between TC-PM2.5 proposed in the analysis of PM2.5 physical formation process is proved by data translation analysis. In the PM2.5 physical formation process, the effect of TC is amplified, the magnification of about 5 times, and carbon particles play a true "source" role in PM2.5 formation. The microscopic analysis of PM2.5 electron microscopy shows that the physical meaning of the mathematical model is highly consistent with the microstructure of the related matter.
