理論計算和模型試驗結果均證明了組合減搖附體能夠減小船的縱搖運動、升沉運動，尤其是大幅度降低首部加速度。 -
Based on the mechanism of slipstream interaction, described in this thesis is firstly the interaction of the propeller slipstream with the wing 、 fuselage and horizontal tail. subsequently, the changes in lift 、 drag and pitching moment are derived, giving an engineering model for the prediction of the increments in the aerodynamic characteristics caused by the interference between the propeller slipstream and the other parts of aircraft. this method offers a powerful means to the calculation of the aerodynamic interaction between the propeller and the aircraft, providing reliable data for the design of and aerodynamic calculation on propeller - powered aircraft
本文以滑流干擾的機理為出發點，研究了螺旋槳滑流與飛機機翼、機身、平尾組合體之間的相互影響，推導出滑流引起的飛機升力、阻力和俯仰力矩的變化，給出了滑流干擾對機體氣動特性影響的工程估算方法，為研究螺旋槳與飛機部件之間的相互干擾提供了有力的工具，為以螺旋槳發動機為動力的飛機的設計和氣動計算提供可靠的依據。 -
Secondly, the non - linear model of ship motion was studied. the non - linear term and the term related to pitching velocity are referred to disturbance of the system to get state feedback designed mathematic model of the rudder / fin joint control system. the non - linear rudder / fin joint control system - designing problem was transformed into disturbance attenuation linear system designing problem, which uses quadratic performance as object function
為了得到船舶舵鰭聯合控制系統的狀態反饋h ~設計的數學模型，把非線性項及與橫蕩速度相關的項也看作是對系統的擾動，把非線性船舶舵鰭聯合控制系統設計問題化為以二次型性能指標為目標函數的干擾抑制的h ~線性系統設計問題。 -
