| Abstract: | It is to be give that insert numerical value model on three-curved moment of force spline function and to be used to resolve a grey forecasting question of Non-isometric Time Sequence GM(1,1).It is stated clearly that an example of grey forecasting question of Non-isometric Time Sequence about international roughness index IRI,which the method keeps period objective law of original data and have characteristics of high-precision and good-practical when turning Non-isometric Time Sequence into isometric Time Sequence. |
