| 摘 要： | 从大气封闭型扩散实际反射路径分析入手,引入上下边界不同的反射率与污染物衰减系数,得出比以往公式更具一般意义的大气封闭型扩散的污染物浓度估算公式,特别适用于边界具有一定吸收能力与污染物质有衰减的情况,从而有效改进污染贡献的估算精度.文中展示的示意图,纠正了以往示意图的错误.

| 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. |

| Keywords: | closed type atmospheric dispersion reflection factor reduction coefficient pollution contribution |
