Abstract: This article applies the grey model approach in the grey system theory to set up the Samedistance Grey munmer's Stepsupplement forecasting model GM(1,1)of the national record of long jump,begin directed against the ambiguity,unknown and so on.It also performs the examinnation of posterior difference and analysis of the relative degree.It turns out the precision of forecasting model is equal to first class(GOOD).At the same time,this model has been applied to forecast the sport achievement of 2002.
