If the infiltration intensity is less then the saturated permeability coefficient, the surface soil finally reaches to an unsaturated infiltration stage instead of saturated infiltration stage.
In this paper was discussed the temperature coefficient method for calculating the gelation rate of unsaturated polyester resin. which is used for expecting the storage life of the resin.
本文提出了不饱和聚脂树脂胶凝速率温度系数的方法，并测定不同温度下的贮存期。

By using this model the soil-water characteristics and permeability coefficient of unsaturated soil are deduced and expressed in fractal dimension and air-entry value.
