• 中文摘要： 本文利用空氣污染擴散「環模式」的觀念，將其適用範圍推展至更廣義的擴散型態，並考慮大氣中各化學物質的化學反應，使其成為「推廣環模式」。惟推廣環模式假設大氣與煙柱混合後未參與煙柱中污染質的化學反應。本文基於推廣環模式的計算過程，更進一步融合較常用的「箱模式」的觀念，加入了大氣與煙柱紊亂混合反應的因素，建立一新的模式，稱為「盒模式」。此盒模式可解決大氣中較複雜的化學反應與擴散的問題，提供一個對大氣污染擴散問題較完整的理論分析模式。最後並以實例來闡明盒模式的實際應用。
• 英文摘要： By extending the application ranges of theRing Concept for the diffusion of pollutants toa more general diffusive condition and by con-sidering the chemical reactions of the reactivepollutants in the atmosphere, a Modified RingModel is established. This Modified Ring Modelassumes that the pollutants originally in theatmosphere do not participate in the chemicalreactions which proceed in the plume. Basedon the calculation procedures for the ModifiedRing Model and the idea of the popular BoxModel, a new model called "Cell Model" isthen established. This Cell Model considers theeffect of the chemical reactions when the plumeand the atmosphere are turbulently mixed andis capable of analyzing the pollutants diffusionwith complex chemical reactions in the atmos-phere. This model provides a more completetheoretical basis for the calculation of chemically-reacting air pollution concentrations. Severalillustrative examples are also presented to dem-onstrate the actual application of the CellModel.
