摘要
利用高灵敏度、高选择性、多组分和快速实时分析探测的方法———激光质谱方法研究机动车尾气。发现在 2 6 6nm激光作用下 ,低速状态下机动车尾气中的芳香族含量远高于加速状态下的含量。
In this article, we have studied air pollutants in the exhaust gas of vehicle using laser mass spectromety, which is characteristic of high sensitivity, high selectivity, multi component and on line real time analysis. Using this method, we find that the concentration of aromatic substances in the exhaust gas of vehicle of low gear status is much more than that of speed up status.
