摘要
介绍了用扫描电子显微镜(SEM)和电子探针微观分析方法(EMA)对城市尘源的粒径分布和其行貌特征进行分析研究的情况和结果。此方法能清楚地了解尘源样的粒径及行貌特征。
This pasage introduce the state and resalt that we use Scan Electrical Microscope(SEM) and the method of Electricalprobe Micro Analysis(EMA) to analyse and study the distribution of particle's diameter of the city's source of dust and the characteristic of its shape and appearance. Through this method we can know clearly the particle's diameter of source of dust and its characteristic of shape and appearance.
