結論

不(bu)(bu)像人(ren)工創造的(de)(de)(de)(de)穩(wen)定(ding)的(de)(de)(de)(de)驅(qu)蟲表(biao)面或(huo)(huo)多孔 介質，拒水(shui)土(tu)(tu)壤(rang)表(biao)現出潤濕動(dong)力學，由此 最初(chu)(chu)疏水(shui)的(de)(de)(de)(de)土(tu)(tu)壤(rang)隨(sui)著(zhu)時(shi)間的(de)(de)(de)(de)推移(yi)變(bian)得親水(shui) 與水(shui)接(jie)觸時(shi)。 初(chu)(chu)始潤濕動(dong)力學 排斥土(tu)(tu)壤(rang)通常(chang)歸因于 固液界(jie)面能(neng) (γSL)，或(huo)(huo)液汽(qi)界(jie)面能(neng) (γLV) 的(de)(de)(de)(de)降低，或(huo)(huo)兩者兼而有之(zhi)。 γLV 的(de)(de)(de)(de)減少 建議是(shi)(shi)由于土(tu)(tu)壤(rang)表(biao)面溶解 活(huo)性有機化(hua)合(he)物(wu)進入與水(shui)接(jie)觸的(de)(de)(de)(de)水(shui)中(zhong) 土(tu)(tu)壤(rang)。 在(zai)這項研究(jiu)中(zhong)，我(wo)們測試(shi)了土(tu)(tu)傳表(biao)面的(de)(de)(de)(de)影(ying)響 潤濕動(dong)力學的(de)(de)(de)(de)活(huo)性物(wu)質，并(bing)發現，與廣為接(jie)受(shou)的(de)(de)(de)(de)范(fan)式相反，土(tu)(tu)壤(rang)釋放表(biao)面 活(huo)性化(hua)合(he)物(wu)不(bu)(bu)會加速潤濕過程。 因此很明顯，固體界(jie)面能(neng)的(de)(de)(de)(de)變(bian)化(hua) 表(biao)面（γSL 或(huo)(huo) γSV），而不(bu)(bu)是(shi)(shi)液汽(qi) 表(biao)面 (γLV) 必須在(zai)驅(qu)動(dong)不(bu)(bu)穩(wen)定(ding)排斥性土(tu)(tu)壤(rang)的(de)(de)(de)(de)潤濕動(dong)力學方(fang)面起主(zhu)導作用。
