Changes of two soil phases in the process of infiltration

According to the variation of the water volume in the wet layer which exists in the stable soil air pressure infiltration and the normal infiltration indoors and outdoors,we have observed the process of the soil air entrapment pressure and the infiltration water flow.Studies have showed that the soil air pressure content of the wetted soil can be divided into three stages:rapid,slow and stable stages.And we have concluded that the section water content in the stable infiltration is 0.97 or 0.50 L/L.
