lag duration 中文意思是什麼
lag duration
解釋
滯后工期-
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。 -
( 4 ) substitute the every precedence relation of precedence construction network with a procedure, and the lag of precedence relation is defined as duration of the procedure which is named as lag procedure. the lag procedure does not consume resource, and the duration is random or determined
將施工搭接網路的每一搭接關系改用新增的工序相連，並將該搭接關系的時距定義為這新增工序的持續時間，把這一新工序稱為時距工序。 -
You can express lead or lag time as units of time or as a percentage of the predecessor task ' s duration
可以使用時間單位或前置任務工期的百分比來表示前置重疊時間或延隔時間。 -
Thirdly, in this thesis, the influence of concrete creep to the behaviors especially to the nonlinear behaviors of reinforced - concrete box girder has also been studied and the effect of creep on internal force, deformation, ultimate load capacity and shear lag of reinforced concrete box - girder has been included, and the parameter such as loading duration, age of concrete and sustained load are considered
採用按齡期調整的有效模量法本文還編制了箱梁徐變效應分析的有限元程序，分析了混凝土徐變對箱梁的內力、變形、極限承載能力以及剪力滯的影響，並著重分析了持荷時間、加載齡期、持續荷載大小對徐變效應的影響。 -
First, the lag in supply response to the stimulus provided by higher prices may prove to be of greater duration than its predecessors, to the extent that the current changes in world energy markets ? and hence the associated demand for biofuels ? are likely to be lasting ones
第一，面對價格上漲的刺激，供給方面的反應可能會比前幾次更為滯后，因為當前世界能源市場的變化，以及由此產生的相關生物燃料需求，可能會持續相當長一段時間。
