摘　　要：本文初步研究了海面上风浪运动对船舶航速的影响,得到了不同吨级船舶的运动性能曲线和失速回归方程,对船舶横渡大洋最佳航线选择和航行模拟有一定实用价值。Through studies on the effect of wind and sea-wave motion on navigational speed of ship-ping,the curve of motion property for diffferent tonnage shipping and the regression equation ofloss-Speed have been obtained.Those are of practical significance to the choice of optimum searoute for trans-oceanic shipping and navigation simulations.
