基于灰色系统等数学方法的中、意职业篮球技术分析

运用灰色关联理论、SPSS统计分析和等级相关分析等数学方法,分析中国和意大利篮球职业联赛2005-2006赛季常规比赛临场技术统计指标,探讨两个独立比赛系统的胜率排名与技术指标的关联关系,以及竞赛结果分差段场次的等级划分特征和得、失分与名次顺序的相关属性值等问题。研究数据显示:中国篮球职业联赛绝大多数参赛队伍具有“重攻轻守”的技术表现特点,意大利篮球职业联赛参赛队比较注重防守技术环节;在比赛的激烈程度和观赏程度方面,意大利联赛明显高于中国联赛;两个竞赛系统同时表明失分顺序与胜率排名的相关程度高于得分顺序与胜率排名。

Technical Analysis of China Basketball Association and Italy's Lega Basket Serie A Based on Gray System and Other Mathematical Methods

This paper makes use of mathematical methods, such as grey relation theory, SPSS statistical analysis, and rank correlation analysis, to analyze the technical statistic index in CBA and Lega A regular games during 2005-2006 season. The paper also discusses the following questions: the relevancy relationship of win rate ranking and technical index, the connections between the match results and the ranking distinctions of two independent match systems. The research data shows that: most teams of CBA pay more attention to attack than to defend, while the teams of Lega A pay more attention to defensive techniques; Lega A is better than CBA in the aspects of offensive; and also the two match systems shows that the related extent of losing order with the ranking are higher than that of winning order.
