摘要/Abstract

摘要： 对城市机动车尾气中NO_x污染物的产生、迁移、转化规律进行了数学分析，提出了城市机动车尾气污染物NO_x随时间和距离变化的数学模式，并运用该模型对长春市内车辆集中路口机动车污染物NO_x进行了模拟与预测。对实验所获得的监测结果与运用数学模式的计算结果进行比较可知：其平均偏差的绝对值小于0.02 mg/m³，相对误差的绝对值均小于0.32，因此城市机动车尾气污染物NO_x的数学模式符合研究区域的实际情况。

关键词: 机动车尾气, 污染物NO_x, 数学模式

Abstract: On the basis of analysis of the production, movement and transforming laws of urban automobile tailing pollutants (NO_x), the mathematical model of urban automobile tailing gas pollutants (NO_x) were presented and applied, to simulate and predict the automobile pollutants(NO_x) concentration on the road with many automobile passing through. The comparison between the monitored data and the calculated results proves that the absolute value of average bias was less than 0.02 mg/m³, the value of relative bias was less than 0.32, which shows that the mathematical model of urban automobile tailing pollutants (NO_x) concentration well reflects the actual situation.

Key words: automobile tailing gas, pollutant NO_x, mathematical model
