摘要
本文提出了用开打次方对原始数列{x^(0)(k)}进行变换,提高离散数据的光滑度,并讨论了有关逆变换误差,实例分析效果是显著的。
This paper proposes to improve the smooth of the original discrete date series {x^(0)(k)} conouting transformation by means of extraction of n square root, and discusses errors of inverse transformation concerned. A practical example shows the effect of the method is remarkable.
