Abstract:	大氣中的氣懸浮微粒通常為非球型的微粒。舉例來說，在South Eastern Aerosol and Visibility Study中發現粒徑在200~800 nm範圍的環境微粒約有10%為非球型的微粒(Dick et al. 1998)。另一方面，大部分利用火焰合成方法(flame synthesis)生成的工業奈米微粒(如：碳、二氧化鈦、矽和鋁等奈米微粒)皆為agglomerates 或是aggregates1。此外，經由高溫產生的環境氣懸微粒(例如柴油引擎的排放汙染物或是煤灰微粒)也都含有許多非球;Atmospheric aerosols are often non-spherical particles. For example, the South Eastern Aerosol and Visibility Study found that about 10% of the ambient particles in the 200–800 nm range were non-spherical (Dick et al. 1998).
