关于新旧排球规则的概率分析

Probability Analysis on the New and Old Volleyball Rules

本文利用排球新旧规则两种得分制得分率的数学模型分析认为,两种得分制的得分期望相同(是某些变量的同一函数),因此技战术应具有某些一致性;同时两种得分制得分率及得分方差有差异,故比赛技战术又有某些不同点。

This paper, through mathematical analysis on the two scoring systems of new and old volleyball rules, thinks that the scoring expectations of the two systems are the same, therefore, there should be unanimity in some techniques and tactics. Meanwhile, because of difference in the two systems, some differences are also existed in techniques and tactics.
