对高校开设中华养生学课程必然趋势的研究

在文献资料的基础上,用辩证唯物主义的观点分析研究了高校以竞技体育为主的教育体系,从本质上难以解决高校学生体质健康问题,而使学生体质呈持续下降趋势。中华养生学经历了几千年众多人的反复实践、探索、研究、提炼、积累而汇集成博大精深的中华养生学知识体系,它不仅使人健康,而且有利德,智等素质的教育,受到世人的青睐,这就是她发展的必然趋势。为了贯彻落实《决定》精神,在高校建立具有中国特色的养生学体系,开设养生学课程,改变学生体质下降趋势,促使人才素质全面发展是非常必要的。     

Water molecules bonded to the carboxylate groups at the inorganic–organic interface of an inorganic nanocrystal coated with alkanoate ligands

High-quality colloidal nanocrystals are commonly synthesized in hydrocarbon solvents with alkanoates as the most common organic ligand. Water molecules with an approximately equal number of surface alkanoate ligands are identified at the inorganic–organic interface for all types of colloidal nanocrystals studied, and investigated quantitatively using CdSe nanocrystals as the model system. Carboxylate ligands are coordinated to the surface metal ions and the first monolayer of water molecules is found to bond to the carboxylate groups of alkanoate ligands through hydrogen bonds. Additional monolayer(s) of water molecules can further be adsorbed through hydrogen bonds to the first monolayer of water molecules. The nearly ideal environment for hydrogen bonding at the inorganic–organic interface of alkanoate-coated nanocrystals helps to rapidly and stably enrich the interface-bonded water molecules, most of which are difficult to remove through vacuum treatment, thermal annealing and chemical drying. The water-enriched structure of the inorganic–organic interface of high-quality colloidal nanocrystals must be taken into account in order to understand the synthesis, processing and properties of these novel materials.     

The History of Modern Organized Badminton and the Men’s Team Thomas Cup Tournaments, 1948–1979

Modern organized international badminton began with the founding of the International Badminton Federation (IBF) in 1934, consisting of nine founding member associations. The inaugural men’s Thomas Cup tournament began in 1948 when 10 countries took part. Malaya won the Cup four times in 1949, 1952, 1955, and 1967. When Indonesia took part in the tournament for the first time in 1957, there were 19 competing teams. Indonesia won the triannual tournament seven times from 1957 to 1979. Throughout the 11 Thomas Cup tournaments, only two Asian countries have won the Cup. The only European country, Denmark, qualified to play in the finals five times without a single win. Malaya (later known as Malaysia), Indonesia, and Denmark became leading Thomas Cup teams because they produced singles and doubles players that won many All-England Badminton Championship titles. The winners of these titles were generally considered the world champions. The key sources of information for this research consisted of the IBF annual statutes for listing of participating nations, tournament programmes, and rare specialized books on badminton and the Thomas Cup competition. English language newspapers such as the Singapore Free Press and the Straits Times published historical match results for checking the secondary data collected.     

机动车燃油质量及尾气排放与北京市大气污染的相关性

采用GC-MS等仪器分析手段对北京市各主要品牌的燃油进行质量分析,并建立以静稳天气下单位体积中的污染物日均变化为相对参照标准计算各污染物贡献率的新思路。首先研究机动车尾气各主要污染物（CO、HC、NO₂和SO₂）在单位体积的日均排放量,然后分别统计北京市两年（2013年11月-2015年10月）大气中各对应污染物实测的单位体积的日均变化量,再分别计算出汽车尾气对大气各污染物的贡献率。结果如下。1）北京市燃油普遍存在重金属含量超标,硫含量超标,不饱和芳烃含量超标,氮含量偏高（无国标制约）等问题。2）在供暖季,北京市汽车尾气排放的CO、NO₂和SO₂分别占总CO、NO₂和SO₂排放的30.1%、72.4%和6.6%;在非供暖季,汽车尾气排放的CO、NO₂和SO₂分别占总CO、NO₂和SO₂排放的53.3%、74.3%和20.3%;北京市汽车HC排放全年平均分担率约为67.8%。研究结果表明,燃油是北京市大气污染的主要原因。最后为北京市大气污染的有效治理提出具体的建议和措施。     

新中国成立以来排球类书籍综述

对1933年至2015年间314本具有代表性的排球类书籍进行对比与分析,结果发现:随着人们对排球运动认识的不断深入,以及各个时期不同的历史背景与特点,排球书籍的种类越来越多,基本可以满足人们对理论知识学习的需要,为了顺应时代的发展,有些地方还需要改进与提高.建议在出版的数量与种类上,继续丰富;在教材的更新上,缩短更新年限,有规律的进行更新.     

我国优秀女子铁饼选手“人-饼”速度指标的运动学分析

摘 要：采用文献资料法、专家访谈法、三维高速影像解析法和数理统计法,对现阶段我国优秀女子铁饼运动员旋转技术的速度特征进行分析,得出以下结论：重心和铁饼的分速度大小及比例对运动员技术风格的形成有重要影响;“人-饼”系统在腾空和过渡阶段是最复杂和最难控制的,这两个阶段的系统变化对形成最佳技术具有决定性作用;我国运动员第二和第三旋转轴的速度传递稳定,第二轴髋关节和膝关节速度决定着位移的方式,第三轴肩关节速度同铁饼的时空特征有较大相关性。

女性运动员EDS的常见相关行为及其防治

进食障碍（eating disorders,EDS）主要是指以反常的摄食行为和心理紊乱为特征、伴有显著的体重改变和/或生理功能紊乱的一组综合征。其主要的临床类型包括：神经性厌食症、神经性贪食症和非典型性进食障碍。运动员存在的进食障碍多为非典型性进食障碍,且以女性居多,其发病的危险性是非运动员女性的3倍以上。本文就女性运动员与进食障碍的关系,以及其发病原因、治疗、预防加以综述,为教学、科研、运动训练等提供一些参考和意见。     

大学生体育消费行为决定因素的定量分析——以湖北为例

对学生的体育消费行为进行分类，通过问卷调查的形式，采用统计、计量分析方法，深入分析每类体育消费行为的决定因素及与决定因素之间的定量关系。结果显示，除体育运动的兴趣爱好等主观因素外，学生年生活费用水平、课程压力大小、性别是影响学生体育实物消费的主要客观因素；学生年生活费用水平、性别是影响学生体育信息消费的主要客观因素；学生来源是影响学生体育劳务消费的主要客观因素。这对更深刻地认识体育消费行为、预测高校学生体育消费支出有重要意义。
