基本解釋[農(nóng)業(yè)科學(xué)]泥沙輸移比[地球科學(xué)]泥沙輸移比[水利工程]泥沙輸移比英漢例句雙語例句The sediment delivery ratio is not correlative with the river basin area, because which is not a influence factor but a units of measurement.流域泥沙輸移比與流域面積不存在固定的線性關(guān)系,其根本原因在于流域面積是度量衡單位,而不是影響因素。The dramatic change of sediment delivery ratio is caused by the formation of artificial sediment sinks, i. e. , sediment-trapping check-dams and reservoirs.泥沙輸移比的變化,主要是由于流域內(nèi)人為沉積匯的形成所致。This paper reviews the previous studies on the relationship between sediment delivery ratio and drainage area which reflects essentially the relationship between sediment yield and drainage area.提出至今所有流域泥沙輸移比與流域面積關(guān)系其實(shí)質(zhì)都是流域輸沙模數(shù)與流域面積的關(guān)系。sediment delivery ratio更多例句詞組短語短語sediment -delivery ratio 沉積物輸送比值channel sediment delivery ratio 河道泥沙輸移比sediment delivery ratio sdr 泥沙輸移比the sediment delivery ratio sdr 泥沙輸移比sediment delivery ratio更多詞組專業(yè)釋義農(nóng)業(yè)科學(xué)泥沙輸移比From long term point of view, sediment delivery ratio of a drainage basin with a control degree reaching 70% can be reduced by around 50% in contrast to pre control conditions. The effect of erosion control is quite significant.從長期來看 ,在治理度達(dá)到 70 %條件下與治理前相比泥沙輸移比減小 50 %左右 ,治理的效益是十分顯著的。地球科學(xué)泥沙輸移比水利工程泥沙輸移比
