| 摘 要： | 介绍了利用PIXE分析技术对汽车尾气颗粒物的分析，获得了尾气颗粒物中的元素组成以及元素含量；同时对环境污染有影响的元素如S，Pb以及对影响污染物排放的元素如Si和Mn等进行了分析和讨论，研究表明，不同型号的汽车尾气颗粒物中，有害元素含量差异很大，虽然使用了汽油，但探测到有些尾气颗粒物中的铅含量还是相当高的，某些车型的汽车尾气中，Si,Mn含量相对偏高，此研究为治理汽车尾气污染提供依据。

| Abstract: | PIXE technique on the analysis of vehicle exhaust particulate is introduced. The element composition and concentration of particulate are obtained. Some elements which are related to environmental pollution such as sulfur, lead, silicon and maganese, were analyzed and discussed in detail by PIXE technique. Nowadays although unleaded gasoline is widely used, the lead concentration is still very high in exhaust particulate. The concentrations of silicon and maganese in exhaust particulate from different model vehicles are also quite high from measurements. It shows that an evidence for exhaust pollution control could be provided from this work. |
