| 摘 要： | 在以影响因子为核心的期刊评估系统基础上,根据关系型动态思维模式,运用多维定位的原则,利用德尔菲意见法、文献法、逻辑推理法,引入引文支持概念,从引文的多学科特征和应用类型两个特征上,利用文献分类法、图表法、多元统计、聚类分析、数值分类等多种方法,对中文体育核心期刊在引文支持元数据中的特征分布值分别进行统计,目的是从多视角对期刊质量重新进行评价,提高社会对使用影响因子评价核心期刊的认可程度。结论:13种核心期刊在多学科上的分布程度为34.84%,超过多学科丰度值的期刊有5种,形成创新性学术期刊集;13种核心期刊在应用类型上的分布程度为5.10%,超过应用类型丰度值的期刊有6种,形成应用性学术期刊集。两集合中的数据经处理后可以参加以影响因子为核心的中文体育核心期刊排序结果的微调。

| Abstract: | Six young speed skating athletes were tested for SJ and CMJ,and DJ in three different heights.The difference in low limbs skeletal muscle elastic potential energy utilization ratio among these athletes were analyzed for the purpose of understanding the mechanics characteristics of skeletal muscle and foreseeing genius for the speed skating event.The results showed that the difference existed between male and female in elastic potential energy utilization ra-tio(higher for male)which positively correlated to the skill degree and body mass.Along with the load increase,the athletes' lower limb muscle elastic poten-tial energy utilization ratio dropped gradually.Under the ex-load condition,the elastic potential energy utilization ratio was lower compared with other projects.It is therefore that in order to increase muscle stability,the training for the muscle speed strength and the high grade long strength should be enhanced. |
