- 中文摘要: 空氣?染對大氨性質最重要而顯著的影響是能見度的減低。無論凝結是否?生,這種情形都會經常伴隨著污染空氣 發生。本文以數字模擬的方法討論,由燃燒所?生的?染物(單成分的、多分散粒子分佈所組成的氣溶膠),如何促成 平流霧之形成。結果顯示,如果氣溶膠的質量濃度保持不變,多分散分佈中,偏向高粒子濃度分佈的氣溶膠,對促成平 霧的形成,與偏向低粒子濃度分佈的氣溶膠比較,具有較優異的條件。
- 英文摘要: The most noticeable effect of air pollution on the properties of the atmosphere is the reduction in visibility, with and without the occurrence of condensation, which frequently accmpanies polluted air. The present study concerns the formation of advection fog associated with aerosols, due to combustion-related pollutants, with a polydisperse population distribution and a single composition model. The results show that an aerosol population with high particle concentration-shifted distribution provides a more favorable condition for the formation of dense fog than an aerosol population with a low particle concentration-shifted distribution if the value of the mass concentration of the aerosols is kept constant.
