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.

The effect of vegetation restoration on soil stable infiltration rates in small watershed of loess gully region;

The application of the research on the experience formula of the soil seepage ability under the condition of pressure-free in spray irrigation seepage;
