摘　　要：介绍Vondrak滤波的基本原理及两种不同的公式求解过程,通过模拟算例指出自回归AR模型并不适用与所有的数据序列。针对现有的时间序列分析模型的完善性以及测量数据的复杂性,提出应该对所得的数据进行模型准确分析,采用合理的时间序列模型对其进行准确的拟合外推,从而可以更好地消除端部效应现象,进而得到更加精确的滤波值。The basic principle of Vondrak filter and solution procedures of two formulas were introduced.Autoregressive（ AR） model was not suitable to all data series by the simulation example. In view of the perfection of the existing time series analysis and complexity of the data,the data model parameters were determined by accurate data model analysis. The reasonable time series model should be used for the extrapolation which can better eliminate the end effects and get more accurate filtering value.
