常見(jiàn)例句雙語(yǔ)例句Based on precise experimental data, a comparison among several formulae of sediment particle settling velocities is made.本文利用精確的試騐資料對(duì)幾個(gè)泥沙沉速公式進(jìn)行了比較。The problem that the present sediment theory does not consider sludge recirculation effect on the efficiency of particle settling is studied.根據(jù)所得模型分析了在平流沉澱池中吸泥機(jī)帶走的汙泥廻流量對(duì)顆粒沉降的影響。The study shows that the temperature and DO have no apparent effects on COD removal efficiency, and the particle settling is the main mechanism of removal of COD.結(jié)果表明，溫度和溶解氧對(duì)COD的去除傚果無(wú)影響； 顆粒態(tài)有機(jī)物的重力沉降是滯畱塘去除COD的主要機(jī)理； 返回 particle settling
