对当今世界女子跳马发展趋势的探讨

以1989、1993、1997年国际女子体操评分规则和2000年奥运会女子跳马决赛为研究材料,采用文献研究、录像观察和数理统计等方法,对1989至2000年世界女子跳马难度动作的数量和2000年奥运会跳马前8名运动员的动作起评分、动作类型与完成情况等进行分析研究.结果表明,跳马技术发展呈现出难度的递增性.运动员掌握高起评分的不同结构组动作和追求动作姿态美、腾空高、落地稳综合技术指标是当今世界女子跳马发展的总体趋向.     

中外优秀女子跳马运动员技术水平对比研究

对中外优秀女子跳马运动员技术水平进行对比研究,结果发现,在伦敦奥运周期中,跳马已成为我国女子争夺团体、全能冠军的严重阻碍.我国女子跳马整体水平薄弱,在单项比赛中,优秀选手难度上有实力争夺奖牌,但动作质量较差,还有待进一步加强.

一抹旋转的彩虹惊艳世界——程菲和“程菲跳”的诞生

北京时间2006年10月20日,安徒生的家乡丹麦奥胡斯,第39届体操世锦赛女子跳马单项决赛中,一套超高难度的动作被中国     

中国女子跳马技术实力分析

跳马是女子体操比赛项目之一。在第41届体操世锦赛上,中国女队派出了杨伊琳、邓琳琳、何可欣和眭禄4位选手对女子个人全能、高低杠、平衡木和自由体操四个项目进行了角逐。为此,专家均认为：程菲之后,中国队已拿不出可到世界赛场争金夺银的选手。而尽快改变目前女子跳马后继无人的局面,也就成为中国女子体操队在伦敦奥运会前所要亟待解决的重要问题之一。本文拟就中国跳马的技术竞争进行系统分析与研究,以期对中国女子跳马技术的不断完善和发展,能提供有效的参考依据。     

论"程菲跳"与双冠王程菲

程菲是中国体操队一名年仅17岁的女子体操运动员,她用科学态度坚持刻苦训练,充分发挥自身的弹跳能力和借助集体智慧,惊人地创造了“踺子后手翻转体180度接前直体空翻540度”世界女子跳马第一跳高难动作,这一高难动作被国际体联命名为“程菲跳”载入史册。“程菲跳”成就了程菲的跳马与自由体操的双冠王,而程菲精神是实现“程菲跳”的主动力。     

跳马前手翻前空翻转体540°动作男女上板踏跳技术的运动学分析

运用运动生物力学分析方法 ,对男女跳马前手翻前空翻转体 54 0°动作进行对比分析 ,总结出他们上板踏跳技术的共性规律 ,找出男女之间的差距和不同 ,以促进女子这个动作向更高难度发展 ,提供一定的理论依据和技术参数     

第39届世界体操锦标赛女子自由体操成套动作编排特征与趋势研究

通过对39届世界体操锦标赛女子自由体操决赛进行统计分析,阐述了新规则下世界女子自由体操的发展趋势,结果表明:女子自由体操成套动作的发展主要表现在多变流畅的连接技术上,以向后的空翻转体540°或900°接向前的空翻为主,多个空翻的直接连接将会有更大的发展,单个空翻类动作的使用将集中于E组难度动作,成套动作的难度和动作质量还有很大的提升空间.     

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.

团图为数的图中的闭团贯数

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

Social and Cultural Influence on Word Meaning

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language.     

汉字倒说

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.
