摘　　要：补偿导管于1984年3月14日首次装船至今，已有数百艘实船采用了该节能装置投入营运，实船使用证实了船模试验所预报的节能效果4～10％。本文介绍在一艘5000吨多用途货船模型阻力自航试验过程中进行补偿导管推力的试验研究。该船模所安装的补偿导管上测得正推力，表明其推力大于自身的阻力，但其量级很小，不是补偿导管产生节能效果的主要原因。Since its first adoption on the full size ship on March 10, 1984, hundreds of ships have been fitted with this compensation ducts and are in service now. Their operation records proved the duct reached the expected 4 to 10% energy saving efficiency predicted by the model testing. The paper introduced in detail the testing and study carried out on its thrust through self-propelled scaled model resistance testing for a 5 000 dwt class multi-purpose cargo ship. Positive thrust is obtained on the model, proving that its thrust is larger than its own resistance. It is however small in magnitude and is not the major reason of energy saving function of the duct.
