摘　　要：首次提出了一种窄浅构型首三球尾船型，并应用三机三桨技术，设计成１０００ｔ三球尾集散两用出川货船．经实船航行试验和营运对比试验证明，该船型在浅水急流航段中航行，具有阻力低、推进效率高等特点．通过合理调度在不同航区中主机的运行状态，成功地解决了长江干线出川货船中普遍存在的装载吨位小、单位功率载货量低、单位油耗高、船舶效率低等问题．A shipform of narrow and shallow scoop type bow and three-bulb stern is proposed. With a three-engine and three-propeller arrangement, a 1 000-t class container and bulk cargo carrier has been designed and manufactured. Full-scale ship navigation and shipping contrast tests show that the flow resistance to the ship is low and the propulsive efficiency is high when the ship sails in shallow but swift currents. By rational control of the operating conditions of the ship engines in different sections of the River, the problems of low total deadweight and cargo tonnage per hp, high fuel consumption and poor efficiency have all been solved.
