摘要
本文综合国内外资料和作者所做的研究与实验，系统介绍排放物作为污染线源的源强计算，单车排放因子的计算模式及其各种修正参数的获取；对常用的线源扩散模式作验证与比较，提出污染物浓度分布的预测方法。
In this paper, combining the information at home and abroad with our test tudies, theestimation of linear road pollutant source strength, Models for calculating vehicle smissionfactors and the determining of their various coefficients are expounded. Several conventionalmodels of pollutant dispersion near roadways are examined and compared. This paper finallyproposes a predicting method for calculating the distribution of the pollutant concentration.
