大气降尘的观测及数据处理方法

摘要

The observation methods ( dry collection and wet collection) and data processing methods ( weighing method and electron microsco-py method) of atmospheric dust were introduced, the amount of atmospheric dust-fall in Beijing was studied.The study showed that the weight of the solid material was obtained by the observation of the weighing method, and the description of the appearance of solid material was ob-tained by the electron microscope method.The emphasis of the two methods was different, which can be more comprehensive to understand the situation of atmospheric dust-fall.%介绍了大气降尘的观测方法（干法收集和湿法收集）和数据处理方法（称重法和电镜法），研究了北京地区大气降尘量。结果表明，称重法的观测结果得到的是降尘的固态物质的重量，电镜法得到的是固态物质外观的描述，2种方法的侧重点不同，结合应用可以更全面地了解大气降尘的情况。
