线源扩散公式的实验应用及检验

The Application and Testing of Line Source Diffusion Formulae

本文采用不同的线源模式，对新建城区公路近、远期汽车排放污染物进行预测，并与实测验证。结果表明，采用汽车污染物扩散模式，预测新建公路对城区大气环境质量影响是可行的。预测结果与实验结果相吻合。

In this treatise,the short and long term Pollutant emissions from motor vehicles on newly built higlway in urban areas are forcasted by using different line source models,ahd the forecasts are checked against measured values. The result shows that it is fea-ible to forecast the impact of newly built highways on the quality of atmospheric environment in urban areas by using motor vehicle dif-fusion models. The forecasted results tally with the measured results.
