摘要
通过对GPS和地震形变时间序列的研究 ,提出了一种新的插值方法———多点 3次样条方法。该方法可以在一定条件下解决时间序列处理中较多数据的缺失问题。对该方法与其它插值方法进行了对比分析 ,并给出了该方法的定量分析结果。
For the analysis of the time series of GPS and seismic deformaton,a new interpolation method named multi-point cubic spline interpolation method is proposed in this paper.Under certain condition by this method the problem of losing many data for time series processing can be resolved.This method is compared with other interpolation methods and the quantitative results by the method are given.
