空气流动

In traditional study of water flow i n vadose zone, little attention is paid to the effect of air entrapment, while this effect is rather important. T here take place not only water flow, but also air flow in vadose zone.

与传统的包气带中水流研究相比，水气二相流更准确地描述了包气带中的水与空气的流动情况，这对更好地了解固体废物处置场中污染物的运动规律具有重要的意义。
