摘　　要：本文以实船调查为基础,对螺旋桨导管内壁焊缝的侵蚀机理进行了研究,并为提高其抗蚀性能而提出了导管的最佳结构形式——E型结构。This article is based on a full scale investigation. A vast amount ot research, work has been conducted in the erosion mechanism ot' the welded seam of the inner surface of the propeller duct. In order to improve its anti-erosive character, an optimum construction type-'type E' of the propeller duct is proposed.
