| 摘 要： | 由于成都市特定的地理环境和逆温差效应的气候特点，成都市的大气污染在横向和纵向上几乎都不能扩散，而只能就地弥漫。本文就利用中子活化这一核分析技术，对成都市不同季节、不同地点的大气飘尘中微量元素（特别是Ａｓ、Ｃｒ、Ｔｈ、Ｕ等有害元素）的变化进行了初步分析。

| Abstract: | Because of special geographical conditions and the climate that has adverse difference in temperature effect,the polluted air of Chengdu City almost cannot be diffused in horizontal and vertical direction,only can be filled the air of local place.Applied Neutron Activation,a nuclear analysis technology,this article primarily analyze the difference of the trace element of floating dust in the air of Chengdu City in different place and different season. |
