男子仰泳全国纪录的灰色GM(1、1)模型及预测

GRAY GM(1,1) MODEL AND PREDICTION OF NATIONAL RECORD OF THE MEN'S BACKSTROKE

本文运用灰色理论中的灰色模型方法，建立了我国男子１００ｍ、２００ｍ仰泳全国纪录的灰色ＧＭ（１、１）预测模型，并进行了后差检验和关联度分析，结果表明，预测模型精度均为一级（Ｇｏｏｄ）．同时，运用该模型对２００１年运动成绩进行了预测．

The authors use the method of Gray Model in Gray Theory to establish Gray GM(1,1 ) Predication Model of national record of men's backstroke 100m,200m in our country, and to do experiment differece test and relation analysis. The result shows that the Precision of Prediction Model is Good. Meanwhile, the authors also use the modal to predict the sport results in 2001.
