摘　　要：本文利用一维非定常模式，研究了城市上空于、湿气溶胶粒子对夜间边界层温度的影响。结果表明，湿气溶胶粒子对低层大气有明显的升温作用，而对中上层大气则起降温作用，同时改变了贴地逆温层结构和边界层稳定度。The effect of dry and wet aerosol particles over a city on temperature field of the nocturnal boundary layer is studied using a one--dimensional nonconstant model. The result indicates that the wet aerosol particles obvious increase the temperature of the lower air, and decrease the temperature of the higher layer. Therefore they change the constructure of the ground--hugging inversion layer and the stability of the boundary layer at the same time.
