本文中介绍的信息主体是针对测量和解释环境空气物理特性的科学家或工程师的。本文解释了测量与明尼苏达州气溶胶分析系统（MAAS）在丹佛，丹佛附近，和附近的英尺。柯林斯，科洛，并根据在美国其他地区测量的数千种粒度分布所学到的知识来检查测量结果。大气颗粒物的起源和物理变化是通过解释粒径分布中出现的模式来研究的。被称为“AHken Nuclei Range”的模式是衡量气溶胶生成的一种方法，而老化的气溶胶则以“Accumulation Range”模式出现。风吹尘、海浪和机械产生的颗粒（如飞灰）会产生“粗颗粒范围”模式。大气环境分为几类背景气溶胶和城市气溶胶，其物理特征由有限的数量描述。
The body of information presented in this paper is directed towards the scientist or engineer who measures and interprets the physical characteristics of ambient air. This paper interprets measurements made with the Minnesota Aerosol Analyzing System (MAAS) in Denver, near Denver, and near Ft. Collins, Colo., and examines the measurements in the light of what has been learned from several thousand size distributions measured in the other parts of the United States. The origin and physical change of atmospheric particulates is examined through interpretation of modes occurring in the size distributions. The mode coined “AHken Nuclei Range” mode is a measure of aerosol generation, while aged aerosols show up in the “Accumulation Range” mode. Windblown dusts, sea sprays, and mechanically produced particles such as fly ash generate a “Coarse Particle Range” mode. The air environment is categorized into several types of background and urban aerosols whose physical characteristics are described by a limited num...
