运用等维灰数递补动态模型对我国蝶泳纪录跟踪预测的研究

Research on the development of record on butterfly stroke in our country with the method of the same pattern grey number fillvacancies in the proper order and dynamin model in grey system

本文运用灰色系统理论中的等维灰数递补动态模型方法建立了我国蝶泳纪录的预测模型 ,并进行了后验差检验 ,结果表明预测模型精度较高。同时 。

This article establishes the foreeasting model of the butterfly stroke record of our country with the method of the same pattern, grey number,fill vacancies in the proper order,and dynamic model in grey system and tekes the examination of detecting differences. The result shows that the foreeasting model is very precise .At the same time,it ferecasts the developing tendency of the butterfly stroke record of 2002 by this model.
