On the basis of establishing the leeway motion model, the laws of the motion are studied and the strategy on ship off-course correction is discussed by using reasonable rudder Angle timely.───在建立船舶偏航运动模型的基础上，对偏航运动规律进行分析，提出适时合理地采用舵角进行偏航控制的策略。
This paper investigates the turning motion of a twin propeller twin rudder ship in regular waves.───本文研究了双桨双舵船在规则波中的回转运动。
