| 摘 要： | 本文利用透射电镜和X-射线衍射技术,对酸雨危害较为严重的重庆市市区大气颗粒物样品进行了较力细致的研究工作。通过对大气飘尘的表面状态、元素组成以及其结合形态的研究,发现粒度较小的球状颗粒物及粗柱状矿物飘尘对酸雨形成影响较大。同时,本文还对酸雨的形成机理进行了一些探讨。

| Abstract: | Transmission electron microscope and X-ray diffraction were used to study airborne particulates collected in Chongqing, Sichuan Province, which are seriously damaged by acid rain. From the results of TEM arid XRD, the informations including surface state, component and compounds could be obtained. Therefore, some conclusions can also be obtained on the formation of acid rain based on these results. |
