安 徽 医 科 大 学 综 合 实 验 报 告 合肥交通干线（翡翠路段）大气污染物综合评价 The Comprehensive Assessment of Atmospheric Pollutants on Traffic Route (Hefei Feicui Road) 中 文 摘 要 [目的] 掌握大气中SO2、NO2采样原理及分析方法；交通噪声监测原理及评价方法；了解翡翠路不同地段不同时间SO2、NO2、噪声污染状况及与车流量关系等的综合评价方法；根据实验要求创建设计性实验。让学生学会如何设计实验，了解科研设计的一般步骤，知道团结协作的重要性。[方法] 对城市交通主干道不同路段、时间内SO2、NO2及噪声进行测量，并记录相应的车流量，研究该干道SO2、NO2及噪声的污染情况以及与车流量的关系。 [结果] 得出该干道存在着不同程度的NO2及噪声的污染，随着车流量的增加NO2浓度增加；未发现SO2污染超标。 关键词：交通主干/环境污染/车流量 Abstract [Objective] Master atmospheric sampling theory and analysis methods of SO2, NO2; master monitoring principle and evaluation methods of traffic noise; Understanding different sections of different mountain-time’s SO2, NO2, noise pollution and vehicular traffic situation and the relationship between the comprehensive evaluation method. In accordance with the requirements of the experiment was to create design experiment; Full mobilization learning initiative, enthusiasm and creativity, and by the application of the knowledge of the topics experiment with self-integrated design. Let students learn how to design the experiment, get to know the general steps to design the scientific research, know the importance of solidarity and collaboration. [Method] In different sections of urban traffic trunk road, time SO2, NO2 and noise measurements, and recording the corresponding vehicular traffic on the main road SO2, NO2 and noise pollution and vehicular traffic, as well as the relationship. [Results]It’s come to the corridors that there are different levels of NO2 and the sound minor pollution of noise, and traffic volume increases with the increase in concentration of NO2.The pollutions of NO2 have no exceeded the standard. Key words: traffic trunk/environmental pollution/vehicular traffic 一、前言： 二氧化硫、氮氧化物是评价空气质量的控制标准之一。空气中的氮氧化物主要包括一氧化氮(NO)和二氧化氮(NO2)。据有关部门统计,随着工业化生产的迅猛发展,特别是煤炭、石油、天然气的大量开采使用,我国多数城市已呈现出NOx深度增加的趋势。因此,了解氮氧化物的来源及危害机理,建立适合的氮氧化物的分析方法,了解其变化规律,对环保管理及环境整治,保障
