Regressive Mathematical Model for Ship's Magnetic Field

本文对船舶磁扬磁偶极子的数学模型,应用逐步回归方法来建立船舶磁场统计的数学模型,由计算机自动选定构成数学模型的最优磁偶极子阵列,以减少对选择初始值的要求,且计算精度高.

When constructing the mathematical model of a ship's magnetic field, the initail values of model paradeters will directly affect the preciseness of calcu- lation.In this paper,the stepwise regressive analyse method to construct the sta- tistic mathematical model of aship's magnetic fiell is used for the mathematical model for the magnetic dipole of the ship's magnetic field.The optimal magnetic dipole array of the constituted mathematical model is automatically selecteted by computer,in order to reduce the requirements of selected initail values and improve the precisenss of calculation.
