扣球是排球运动的一项重要技术,本文运用模糊数学的方法,分别把提高扣球技术和选得的21种练习设为“论域”U和“相关因素集”X,把体现高水平扣球技术的“高、快、准、变”和每种练习看成是它们的元素,并建立模糊相关矩阵表,把它们间的每个相关记为模糊关系R数,邀请专家用五级分制判别评分,通过运算,筛选出相关系数值大者为最佳训练手段,使专家的宝贵经验定量化,运算的结果还可以查到每种练习与扣球的各种技术目的,任务的相关系数值,为教学、训练提供参考。
Spiking is an important technique of volleyball. In this paper, 21 kinds of exercises to improve the spiking technique and selection are respectively set as “universe of discourse” U and “related factor set” X by using fuzzy mathematics method, Spiking technique “high, fast, accurate, variable” and each exercise as their elements, and the establishment of fuzzy correlation matrix table, each of the correlation between them as the fuzzy relationship R number, invited experts with five Divided into three parts to determine the score, through the operation, the filter out the larger value of the correlation coefficient for the best training methods, experts valuable experience quantified, the results of the operation can also be found for each practice and spiking for a variety of technical purposes, tasks Correlation coefficient values for teaching, training provide a reference.
