  • surface running fluid
例句與用法
  • 4 ) numerical simulation running of surface runoff shows simulation results presented the general features of surface runoff generation , and certain efficiency . after adjusting the input parameters , the simulation results show a good meet to the observed data
    4 )表面徑流的數值模擬能揭示表面產流的一般趨勢,而且有一定的有效性,通過調整模擬輸入參數,能使模擬達較理想程度。
  • 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;當雨前土壤較干燥,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征無關。
  • The objectives of this study were : i ) to understand the mechanism of applying polyacrylamide ( pam ) to control crust formation , to increase infiltration and reduce soil erosion ; and ii ) to quantify the dynamics of soil erosion processes with rare earth elements ( ree ) tracers
    本文的目的是研究利用聚丙烯酰胺( pam )作為土壤改良劑來抑制土壤表面結皮,增加降水入滲,減少土壤表面徑流,降低土壤侵蝕;同時采用稀土元素( ree )示蹤土壤侵蝕的動態過程,研究土壤侵蝕的動力學機理。
