  3. The experiments reveals that : the amount of water vapor transfer is affected by both water content gradient and the value of water contents, when the water content of one end is approximate, the water content gradient increases, then the amount of water vapor transfer increases ; when the water content gradients are approximate, the amounts of water vapor transfer can get great differences if the water contents are different, under this condition when the water content of the dry soil is very little, the amount of water vapor transfer is much greater ; the differences of density hav n ' t great effects on water vapor transfer, but have some effects on the admixture transfer, when the density is smaller, the amount of admixture transfer is greater. the water vapor transfer finishes more quickly and need less time, and the liquid water finishes more slowly and need less time

    當一端含水量一定時，增加含水量梯度，則氣態水遷移量增大；當含水量梯度相近時，氣態水遷移量隨含水量不同可能相差很大，這種情況下當較干段含水量特別小時，氣態水遷移量相對較大；密實度的大小對于氣態水遷移的影響並不明顯，但對液態水和氣態水的混合遷移有一定的影響，在相同的實驗時間內，土體密實度較小，則混合遷移量相對較大；氣態水遷移完成速度較快，所需時間較短；液態水遷移完成速度較慢，所需時間較長。
