| 摘 要： | The transformation of parallel translation can improve the smoothness of discrete series sometimes. In this paper, for ship pitch, a method to modify the system error is proposed via the transformation of parallel translation, which can give the optimize parameters using the Method of Minimum Squares. The series in the method can fit white exponential law better, and then be applied in GM( 1,1) very well. The numerical experiments imply that the method is practical, which make the ship pitch system model more accurate than GM (1,1).
