| 摘 要： | 通过实测资料和理论计算的对比分析，认为在有风条件下对源参数作适当修正后，可以利用线源模式预测公路汽车尾气扩散浓度分布，同时提出了适合高速公路汽车尾气扩散浓度预测的源参数修正方法，可供高速公路环境影响评价时参考。

| Abstract: | Based on the data compared between theoretical calculation and measurement, a reliability of highway vehicle exhaust diffusion model has been conducted. The result showed that by modifying some parameters, such as source size and wind speed, the model can be applied to prediction of concentration distribution of vehicle exhaust more accurately. The paper also gave a simple way for expressway pollution diffusion modelling by means of revising the vehicle exhaust strength in considering the fact that automobile travels much faster on expressway than on highway. |
