結(jié)論

不像人工創(chuàng)造的穩(wěn)定的驅(qū)蟲表面或多孔 介質(zhì)，拒水土壤表現(xiàn)出潤濕動力學(xué)，由此 最初疏水的土壤隨著時間的推移變得親水 與水接觸時。 初始潤濕動力學(xué) 排斥土壤通常歸因于 固液界面能 (γSL)，或液汽界面能 (γLV) 的降低，或兩者兼而有之。 γLV 的減少 建議是由于土壤表面溶解 活性有機化合物進入與水接觸的水中 土壤。 在這項研究中，我們測試了土傳表面的影響 潤濕動力學(xué)的活性物質(zhì)，并發(fā)現(xiàn)，與廣為接受的范式相反，土壤釋放表面 活性化合物不會加速潤濕過程。 因此很明顯，固體界面能的變化 表面（γSL 或 γSV），而不是液汽 表面 (γLV) 必須在驅(qū)動不穩(wěn)定排斥性土壤的潤濕動力學(xué)方面起主導(dǎo)作用。
