When soil antecedent condition is dry and the initial rainfall intensity is high, peak surface runoff also considerably lag behind that of rainfall, because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response, only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism, and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h, indicating the existing of macropores and pipe flow in cultivated layer
2 ）耕作制下紫色土的產流主要機制是： 1 ）當雨前土壤含水量未達到飽和狀態時，表面產流起始時間有明顯滯后現象，這與紫色土的快吸水性和較多非毛管孔隙密切相關；當雨前土壤較乾燥，降雨初期雨強較大時，易形成臨時相對不透水表層，表面產流峰也有明顯滯后現象。 2 ）表面徑流的產流方式主要是超滲產流，當土壤達到飽和狀態后，有四川大學博士學位論文小部分回歸流發生，但主要是飽和超滲產流發生，因為紫色土的相對不透水層和其它透水障礙層不明顯。 3 ）壤中流主要是飽和產流，與降雨過程有明顯的滯后，而且雨停后的壤中流產流歷時與降雨特徵無關。 -

Based on experiments and theory analysis in the past, here we present the most important technology conditions that affecting photosensitivity : 1 、 cycle times, experiments showed that with the increase of cycle times, photosensitivity got worse ; 2 、 h dilution ratio, with the continuously increase of h dilution ratio, h ’ s bombardments on the growing surface enhanced continuously too. these bombardments can eliminate high - energy default configurations priorly and leave stable configurations behind. therefore, growing layer ’ s configurations are impacted ; default state density is decreased and photosensitivity is improved
Layer - by - layer方法的制備工藝條件很多，我們在以往實驗和理論分析的基礎上，介紹了對光敏性影響最為重要的工藝條件: 1 、循環次數的影響，實驗表明隨著循環次數地增加，光敏性變差; 2 、 h稀釋比的影響，隨著h稀釋比的不斷增加， h對生長表面的轟擊不斷增強，這些轟擊能優先消除高能缺陷結構而留下穩定的結構，從而使生長層結構緻密，減少缺陷態密度，提高薄膜的光敏性。 -
