| 摘 要： | 分析了沪杭甬高速公路两侧环境空气中的分布浓度及其递减规律 ,通过实测数据揭示了 NOx分布同距离、车流量及气象条件间的关系 ,并发现 NOx浓度随距离的分布可以用一级指数衰减方程加以模拟 ,在所研究的空间距离内NOx浓度与距离用一元三次方程回归的相关指数接近 1 .0 0 0

| Abstract: | The concentration distributing of NOx and its degression rule in the atmosphere beside the Hu Hang Yong highway were analyzed in this article The relationship between the concentration distributing of NOx and distance, relation with vehicle flux and weather condition were unveiled by field test The results showed that the concentration distributing of nitrogen oxides along with the distance from the highway might be simulated by first order exponential decay formula and its correlation exponent regressed by third order polynomial approaching 1 000 |
