。最近的一项研究表明,城市空气中的柴油颗粒在平流到更清洁的大气中时会发生蒸发收缩(Harrison等人,2016)。我们用结构化和系统的方法研究了成核型柴油颗粒(直径30 nm)对颗粒组成、饱和蒸气压和质量调节系数fi的变化的敏感性。我们使用了一个基于替代分子(C16−C32正构烷烃)挥发度的多组分气溶胶微物理模型。对于标准大气条件(298K,1013.25百帕)和与邻近尺度(长达1公里)的扩散有关的超时间尺度(约100 S),选择特定的水汽
. A recent study demonstrated that diesel particles in urban air undergo evaporative shrinkage when advected to a cleaner atmosphere (Harrison et al., 2016). We explore, in a structured and systematic way, the sensitivity of nucleation-mode diesel particles (diameter < 30 nm) to changes in particle composition, saturation vapour pressure, and the mass accommodation coefficient. We use a multicomponent aerosol microphysics model based on surrogate molecule (C 16 − C 32 n -alkane) volatilities. For standard atmospheric conditions (298 K, 1013.25 hPa), and over timescales (ca. 100 s) relevant for dispersion on the neighbourhood scale (up to 1 km), the choice of a particular vapour
