常見例句雙語例句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麪積不存在固定的線性關(guān)系,其根本原因在於流域麪積是度量衡單位,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,主要是由於流域內(nèi)人爲(wèi)沉積滙的形成所致。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麪積關(guān)系其實質(zhì)都是流域輸沙模數(shù)與流域麪積的關(guān)系。 返回 sediment delivery ratio
