摘要:
首次采用量纲分析法(π定理),在确定城市道路汽车(含其他机动车)尾气污染物扩散影响因素的基础上,求导并建立了尾气扩散箱型模式的普遍式.模式待定参数少,运用方便.它不仅与由质量守恒定律求得的结果一致,而且包括了目前国内外根据实测或实验资料建立的多个箱型(经验)模式.该模式运用于北京某大街及3个城市的综合交通规划中,污染物预测质量浓度与实测质量浓度相关显著,表明模式的建立过程是科学的、合理的.该模式可用于城市道路大气环境质量评价与污染物浓度预测,并可提供相关决策依据.
Abstract:
Based on the factors that affect the diffusion of vehicle exhaust gas for urban road, the general equation of diffusion box model of vehicle exhaust gas is established by analyzing dimensions. This model contains only a few parameters and can be put to use easily. It accords with the results based on the law of mass conservation, and covers the current box models based on experience. When the model was applied to one street in Beijing, the calculating concentration of CO was remarkably related to the monitor one. The result shows that the method is scientific and reasonable. The model can be applied to the air environmental quality assessment of urban road and the forecast of concentration of pollutants.
