by taking loess samples and sandy soil samples for test, vaporous water transfer in unsaturated soil on the condition of constant temperature is studied;
当土体水分主要以结合水存在时,含水量梯度影响下的气态水迁移量大于液态水迁移量;
if soil water mainly is bound water, and a water content gradient is exerted on the soil, it can be found that vaporous water transferring quantity is greater than liquid water transferring quantity.
