摘　　要：大长宽比肥大船型是内河限制性航道大吨位船舶的优选船型,我国有关该船型的研究不多,初步设计阶段湿面积估算没有现成的公式和经验可资借鉴.为解决此难题,作者通过系列船型参数的变化,运用NAPA系统设计了12条船模,分别计算了每条船模5个排水量下的湿面积,给出了该船型湿面积系数图谱和相关的回归公式,供设计人员查阅使用.Among large capacity vessels navigating restrictive channel in Continental River,the large length-width ratio ship is prior to choose.We don＇t know too much in the study of this ship model field in china.Meanwhile neither known formula nor ready-made experience we can make use of during estimation of wet area at the preliminary design stage.In order to solve this dilemma,the author designed five kinds of wet areas under for each ship model,also furnished relative regression formulas and coefficient diagrams of the wet area of the ship to ship designers by means of analyzing varieties of the parameter among the ship model series and using NAPA software system.
