泥艙船 的英文怎麼說
中文拼音 [nícāngchuán]
泥艙船
英文
hopper barge-
The process of effluent flow during loading in self - propelled trailing suction hopper dredgers was simulated by way of physical modeling and was measured and analyzed by using the flow rate and concentration of spoil in the hoppers, particle sizes of sediments at the inlet and outlet of the effluent flow pipe and hopper volume as the major control parameters
摘要通過物理模型試驗模擬自航耙吸挖泥船裝艙溢流施工過程，以艙內流速、艙內濃度、溢流進出口泥沙粒徑、裝艙量幾方面為主要控制因素，進行實測、分析，並比較自航耙4種常用裝艙裝置的消能效果。The results of the analysis of the investment wax and wane balance point prompt that the balance point of building 18000 - m3 self - propelled trailing suction hopper dredgers is higher and the anti - risk capacity is weaker
25年，還貸期小於8 26年。對投資的盈虧平衡進行分折結果表明，建造艙容is000m 』自航耙吸挖泥船盈虧平衡點較高，為74Because the hull scale is big for large self - propelled trailing suction hopper dredgers, and the automatic degree of the equipments is high, the abroad shipyards i special of europe have the ripe experiences to build such dredgers, which with cad to guarantee the building quality and the time limit for project. relatively, the national shipyards never built such dredgers that hopper volume over 4500 m3. although building the dredgers at home, many be spare and to encourage the development of shipbuilding technique, but the building quality and the time limit foe project cannot be guaranteed
大型自航耙吸挖泥船的船體尺度大，設備裝備的自動化程度高，國外特別是歐州大型造船廠建造此類挖泥船具有成熟的經驗，他們採用電腦輔助設計和輔助建造可保證質量和工期，相對而言，國內的造船廠這些年從未建造過艙容超過4500m ~ 3的中型自航耙吸挖泥船，更沒有大型自航耙吸挖泥船的建造經歷，雖然據估算，在國內建造挖泥船可節省一些投資，又可藉此激勵國內造船技術的發展，但其建造質量和工期難以保證，權衡利弊，以選擇國外建造大型自航耙吸挖泥船的方案為好。Shipbuilding - bilge mud boxes for machinery spaces and tunnels - general design characteristics
