  9. The phase change of soil moisture and inflation of the frozen moisture c ause the reduction of hydraulic conductivity by reducing the area of flow section and the aperture of soil pore space, increasing the capillary resisting force to soil moisture, and decreasing the water potential gradient because of the increasing of movement distances of soil water

    導水率減小是凍結土壤入滲能力減小的根本原因，而土壤中液態水的相變是導水率減小的根源所在。土壤水分的相變及其膨脹通過減小土壤水分過水斷面面積和孔隙孔徑，增大阻力和由於增長運動距離而減小水勢梯度使凍結土壤的導水率降低。
  10. Critical hydraulic gradient

    臨界水力陡度
  11.
