香烟烟雾、熏香烟雾、天然气火焰、丙烷燃料火焰和蜡烛火焰是室内气溶胶颗粒的贡献者。为了给吸入气溶胶沉积模式的建模提供定量依据，我们测量了这五个源的吸湿性颗粒的生长以及源的尺寸分布。由于实验是在单一粒径颗粒的基础上进行的，它不仅提供了每个源的平均颗粒的吸湿生长情况，而且还提供了整个粒径谱内不同粒径颗粒的详细粒径变化情况。来源颗粒尺寸分布测量发现，香烟烟雾和熏香烟雾的颗粒尺寸在100-700纳米之间，而天然气、丙烷和蜡烛火焰产生的颗粒尺寸在10 - 100纳米之间。吸湿生长实验表明，根据颗粒大小和来源的不同，这些燃烧气溶胶颗粒可以生长10%到120%。
Cigarette smoke, incense smoke, natural gas flames, propane fuel flames, and candle flames are contributors of indoor aerosol particles. To provide a quantitative basis for the modeling of inhaled aerosol deposition pattern, the hygroscopic growth of particles from these five sources as well as the source size distributions were measured. Because the experiments were performed on the bases of particles of single size, it provided not only the averaged particle's hygroscopic growth of each source, but also the detailed size change for particles of different sizes within the whole size spectrum. The source particle size distribution measurements found that cigarette smoke and incense smoke contained particles in the size range of 100-700 nm, while the natural gas, propane, and candle flames generated particles between 10 and 100 nm. The hygroscopic growth experiments showed that these combustion aerosol particles could grow 10% to 120%, depending on the particle sizes and origins.
