摘要
本文对用速率面拟合法研究地壳垂直运动时所用的多面函数进行了分析研究。指出与多项式拟合法相比,多面函数具有较高的内插精度、较广的适用范围等优点。就地壳垂直形变分析的实际情况而言,不宜采用高阶的核函数。
In this paper, authors analyze several characteristics about multisurface function in studying crustal vertical movement by the fitting method of velocity surface; and point out that, comparing with multinomial fitting method, multisurface function shows higher interpolation precision and wider application field.For the crustal vertical deformation analysis,higher-order kernel function is not sortable.
