【摘要】 通过对武汉市珞狮路路段的车流量、NOx 浓度和气象要素的调查与监测 ,分析了珞狮路交通流量的特征 ,给出了源强的计算公式 ,并重点讨论了街道两侧环境中 NOx 浓度与各种影响因素之间的关系 ,发现城市低矮峡谷中 NOx 扩散不同于以往的研究结果 ,有其自己的特殊性。最后提出了扩散模式参数的处理方法 ,为建立城市低矮街道峡谷排放 NOx 扩散模式提供了基础更多还原

【Abstract】 Based on investigation of vehicle flow、NO x concentration and the meteorological features of Luoshi Road, to analyze the characteristics of traffic flow, decide the formula of exhaust emission, and focuse on the relationship between the NO x concentration in the street environment and the different factors, it is found that the law of NO x dispersion in the low street canyon is different from the former result, at last, the parameters of the dispersion model is revised. The paper provides foundation for the low street canyon NO x dispersion model.更多还原
