因此本文针对船舶耐波性能的优化，提出了一种减纵摇组合附体，将半潜艏和艏鳍安装在常规单体船上，初步阐述了半潜艏和艏鳍的水动力作用机理，并按照二维切片法和高速细长体理论计算了加装组合附体后，船舶在规则波中的垂向稳态运动响应，与裸船体的结果进行了比较，验证组合附体的减摇效果，从船体本身出发提供了?种优化船舶耐波性的方法； 3 - This method makes it possible for investigating the unsteady nonlinear potential flow in a complicated environment with higher efficiency . the aerodynamic forces of a wing in couple motion of heave and pitch with ground effect are analyzed in detail based on the numerical result . it is shown that a thrust force exists when the wing is in heave motion
深入系统地分析了存在表面效应时机翼运动规律和气动力之间的关系，研究结果表明，机翼升沉运动产生的推力与升沉速度幅值的平方成比例，推力和推进效率和振荡频率成反比；机翼的俯仰运动可以调节推力和推进效率，但是单纯的俯仰运动不会产生推力。
