摘要
工程上应用的大气污染物扩散模式中 ,熏烟模式由于其非定常性而与其他扩散模式有很大的区别。正确处理模式中各参数及变量的相互关系才能客观地反映污染物对环境影响的结果。本研究通过对熏烟模式的非定常性和各参数、变量相互关系的分析 。
The atmospheric pollutant dispersion models applied to engineering greatly differs from other dispersion models due to their unsteady flows.Only the relationship between the parameters and varibables of the smoking dispersion model is handled correctly,can the correct results of atmospheric environmental impact from pollutants dispersion be obtained.Based on the analyses of the relations between unsteady models,their parameters and variables,the methods of using correctly the models are also proposed.
