摘要
文中首先从理论上阐述了运用多项式曲面和加权平均拟合高程异常的不足,在此基础上提出了一种新的拟合方法即基于多项式曲面的加权平均拟合法,该方法分别考虑了对高程异常的中长波项和短波项的拟合。试算结果表明:该方法可以很好的改善高程异常的拟合精度,使该方法的适用性也大大增强。
The paper elaborates theoretically the defect of applying the multinomial curved surface and the weighted average models to fit the elevation abnormality.And then a new fitting method,i.e.multinomial curved surface-based weighted average fitting method,is put forward in the paper,which includes the fits of medium-,long-and short-waves of the elevation abnormality.The computation results indicate that this method can improve greatly the fitting precision of the elevation abnormality and has wide applicability.
