常見(jiàn)例句雙語(yǔ)例句Owing to the effects of changing climate and frequent human activities, the annual runoff series for water resource assessment calculation has lost their consistency.由于受氣候變化和頻繁人類(lèi)活動(dòng)的影響,用于水資源評(píng)價(jià)計(jì)算的年徑流序列失去了一致性。From the forecasting results obtained, it can be concluded that the annual runoff has indistinctive decreasing trend and obvious periodical change and stochastic change.從模型的識(shí)別過(guò)程可得,烏拉斯臺(tái)河年徑流具有不顯著的遞減趨勢(shì)和明顯的周期變化,同時(shí)具有一定的隨機(jī)性。Pollution loading of dissolved N and P in ChaoHu lake watershed could be evaluated through export model of N and P after annual runoff volume was work out according to SCS model.流域溶解態(tài)N、P污染負(fù)荷估算是由SCS模型得到流域年徑流量,然后由溶解態(tài)N、P輸出模型計(jì)算得出。 返回 annual runoff
