【Abstract】 Counting for the upper and down boundary’s reflection factors and the reduction coefficients of atmospheric pollutants,a more universal estimation model of closed type atmospheric dispersion was deduced out from diagramming and analyzing its real reflection paths.Especially,the new model can be applied to the situations when considering boundary absorption and pollutant reduction,and it can greatly improve the estimation precision of pollution contribution.The mistakes of illustrating figures in previous literatures were put right in this paper.更多还原
