Moreover, there are good fitted power function relationship between thermal conductivity and soil water content, soil water suction and salt concentration. meanwhile, based on the measured data of soil water content and soil temperature distribution under temperature - controlled conditions, according to philip ' s empirical equation, through difference method, the water diffusivity under temperature gradient was calculated, which can be expressed as a power function of temperature
此外，研究表明，導熱率與土壤含水率、土壤水吸力、含鹽濃度之間均存在良好的冪函數關系；在取得一定溫控條件下的土壤水分與溫度分佈實測資料的基礎上，根據philip經驗方程，通過差分法計算得出溫差作用下的水分擴散率，該參數可表示為溫度的冪函數形式。
