在研究人类呼出气溶胶在疾病传播中的潜在作用时，一个重要的出发点是全面了解呼出气溶胶的生成过程，包括气溶胶粒径分布、所涉及的各种液滴生成机制以及呼吸道内相应的生成部位。为了达到这一理解水平，我们整合了两种不同的调查技术的结果，这些技术跨越了30年的粒度，从700 nm到1 mm，呈现出单一的复合粒度分布，并确定了该分布中最突出的模式。我们将这些模式与特定的原产地和生产机制联系起来。使用空气动力学粒度分析仪（APS）获得该数据，覆盖范围为0.7
An essential starting point when investigating the potential role of human expired aerosols in the transmission of disease is to gain a comprehensive knowledge of the expired aerosol generation process, including the aerosol size distribution, the various droplet production mechanisms involved and the corresponding sites of production within the respiratory tract. In order to approach this level of understanding we have integrated the results of two different investigative techniques spanning 3 decades of particle size from 700 nm to 1 mm, presenting a single composite size distribution, and identifying the most prominent modes in that distribution. We link these modes to specific sites of origin and mechanisms of production. The data for this were obtained using the Aerodynamic Particle Sizer (APS) covering the range 0.7
