摘要
本文通过定理的充分必要性的证明给出了寻找提高原始数据序列光滑度的变换的途径，对获得新的变换具有指导意义，实例分析和误差讨论充分展示了这一寻找方法非常有效。
Abstract The GM modelling method which has been videly used arouses people's attention tothe modelling condition, method and precision. The transfonnation of logarithmic functionand the transfonnation of power function have been separately adopted in [l] and [2] to handleoriginal sequences for heightening the smooth degree of sequences, therefore the GM modellingprecision is improved and the effect is notable. In this paper, the theorem that has theinstructive meaning for getting any other transfoimation gives the way to seektransformations for heightening the smooth degree of original discrete data. We can seethis way is very effective through the analysis about actual example and the discussion abouterror control.
