常見例句雙語例句It is very important for study of mechanics of bed-load transport and of bed-load transport rate.這對于了解推移質運動機理及進行推移質輸沙率研究有著重要的意義。An appropriate formula of bed load rate is chosen to calculate the amount of bed load of each section. Curves of amount of bed load and discharge are got.比較選用能較適用于該河段的推移質輸沙率公式,計算出各斷面的推移質輸沙量,得出推移質輸沙量與流量的關系曲線。The formulas of velocity distribution, flow resistance and bed load transport rate are obtained, in which the flow and sediment movement are considered simultaneously.本文還導得動平床情況下的流速分布公式、阻力公式和輸沙率公式,使動床的水流運動和輸沙過程得以聯(lián)解。 返回 bed load rate
