摘　　要：船舶设计初期,需要估算船舶剩余阻力系数以预报实船阻力,通过AUTOLISP语言编程,实现对有限数据库样本的髙效整合,筛选出有效样本,在三维数据空间完成数据插值,实现对剩余阻力系数的预报。经过多算例验证,预报结果与水池试验数据之间的误差可控,能满足初期设计工作的需要。At the early stage of ship design, it is necessary to estimate the ship resistance by predicting the residuary resistance coefficient. The program written with AUTOLISP language could make good use of limited samples to finish interpolation calculation in three -dimensional sample space. It was proved that the residuary resistance coefficient results calculated by the program were exact and credible compared with data of towing tank, ensuring the accurcy of the estimation in the early design stage.
