少儿跳水运动员比赛心理探析     

成晶晶  胡卫东 《南京体育学院学报(社会科学版)》2002,16(6):90-91

少儿跳水运动员在比赛时一般会出现四种情绪状态,其中三种情绪状态,即过分激动状态,淡漠状态,盲目自信状态对运动员的技术水平发挥有消极的影响。要求教练员能及时发现,寻找原因,采用不同的方法对症下药,区别对待。只有把运动员调整到第四种情绪状态——战斗准备状态,才能发挥出良好的技术水平。  相似文献

本文论述一个由单片机和双端口存储器构成的加密机,阐述了加密机的工作原理和操作流程.由于双端口RAM的采用,支持中断机制,同步与协调控制单片机与算法单片机并行工作,双端口RAM弹性连接控制单片机与算法单片机,匹配它们的传输速率和处理能力,提高了加解密的处理效率,控制单片与主机之间可进行全双工通信,这样的传输可以节省控制单片机的时间,提高效率.  相似文献   

Quantifying the offensive sequences that result in goals in elite futsal matches     

Hugo Sarmento  Paul Bradley  M. Teresa Anguera  Tiago Polido  Rui Resende  Jorge Campaniço 《Journal of sports sciences》2016,34(7):621-629

The aim of this study was to quantify the type of offensive sequences that result in goals in elite futsal. Thirty competitive games in the Spanish Primera Division de Sala were analysed using computerised notation analysis for patterns of play that resulted in goals. More goals were scored in positional attack (42%) and from set pieces (27%) compared to other activities. The number of defence to offense “transitions” (n = 45) and the start of offensive plays due to the rules of the game (n = 45) were the most common type of sequences that resulted in goals compared to other patterns of play. The central offensive zonal areas were the most common for shots on goal, with 73% of all goals scored from these areas of the pitch compared to defensive and wide zones. The foot was the main part of the body involved in scoring (n = 114). T-pattern analysis of offensive sequences revealed regular patterns of play, which are common in goal scoring opportunities in futsal and are typical movement patterns in this sport. The data demonstrate common offensive sequences and movement patterns related to goals in elite futsal and this could provide important information for the development of physical and technical training drills that replicate important game situations.  相似文献

Structural Reliability of Broadside of a Bulk Carrier     

黄衍顺  涂跃红王琳 《天津大学学报(英文版)》2005,11(6):417-421

The ultimate bending moment and maximal shear stress of a bulk carrier with two structural forms （single hull and double hull/ are calculated separately by using the combined moment which is determined by stochastic process. Then the assessment of reliability is carried out. The results indicate that by introducing the double-hull structure, the shear stress of side can be decreased to half of that of the primary structure（ 50.7% i. but the effect on longitudinal strength is not obvious. Finally, the effects of different double-side skin widths on ultimate bending moment and the maximal shear stress are investigated, followed by proposals of the selection of the double-side skin width.  相似文献
