| 中文摘要 |
| 采用Briggs大气扩散参数的一般式(σ=αχ(1+βχ)-1/2)将国内一些实测大气扩散参数组织拟合,求出高架源大气扩散参数。拟合大气扩散参数经与GB3840-91和Briggs大气扩散参数比较结果合理,一般适用于100m以上的高架源扩散情况。因此在大气扩散计算中有实用价值。 |
| 英文摘要 |
| In a calculation of the atmospheric dispersion of emissions from a high overhead source,the atmospheric dispersion parameters given in the National Standards GB3840-91 and the Briggs parameters were found to be no longer suitable. By using the general expression for the Briggs atmospheric dispersion parameters(σ=αx(1+βx)-1/2) to fit the atmospheric dispersion parameters which were actually measured in various parts of China,the fitted parameters were obtained and were found more reasonable as compared with the GB3840-91 and Briggs parameters, and thus have a practical value in use for calculating other atmospheric dispersion parameters. |
