PHOTON-SUBTRACTED (-ADDED) THERMO VACUUM STATE AND THEIR APPLICATION IN JACOBI POLYNOMIALS

We construct photon-subtracted (-added) thermo vacuum state by normalizing them. As their application we derive some new generating function formulas of Jacobi polynomials, which may be applied to study other problems in quantum mechanics. This will also stimulate the research of mathematical physics in the future.     

商品包装设计中的文化美感对消费行为的影响

随着社会经济的发展,人们对商品的包装提出了更高的要求,提高商品包装的艺术美感,突出人文气息、提高商品的文化内涵成为现代包装设计面临的又一个重要课题。而要把握好商品包装设计审美中的文化内涵趋向,包装设计的材料美、色彩美、造型美则起着主导作用。对产品进行文化定位,对消费群体的文化心理进行全方位的了解,使产品外包装所表现的文化内涵与消费者产生知觉共鸣,才能促使消费者产生购买商品的欲望与行动,从而影响消费行为,通过包装达到启迪消费的功能。     

英语Antonomasia辞格中名称转义及其修辞作用

英语Antonomasia辞格可理解为从基本命名义素派生出新意,是英语词汇意义改变和新义产生的手段之一．所涉及的许多词汇具有鲜明的西方民族文化色彩。出现在Antonomasia辞格中名词有两类：专有名词和普通名词,它们有历史、政治、宗教、文学等渊源。这里的人名、地名、事物名称等都“出身名门”,有着不同凡响的背景．很容易唤起与之相关的联想,形成一种耐人寻味的意蕴,从而构成词的隐喻性或借代性的转义。     

The effects of warm-up on intermittent sprint performance in a hot and humid environment

It is unknown whether a passive warm-up or an active warm-up performed at an intensity based on lactate thresholds could improve prolonged intermittent-sprint performance either in thermoneutral or hot environmental conditions. To investigate this issue, 11 male athletes performed three trials that consisted of 80 min of intermittent-sprinting performed on a cycle ergometer, preceded by either an active or a passive warm-up. Active warm-up and intermittent-sprint performance were performed in both hot and thermoneutral environmental conditions, while passive warm-up and intermittent-sprint performance were performed in hot conditions only. First sprint performance was also assessed. Results showed no significant interaction effects between any of the trials for total work (J · kg(-1)), work decrement, and power decrement (P = 0.10, P = 0.42, P = 0.10, respectively). While there were no significant differences between trials for work done for first sprint performance (P = 0.22), peak power was significantly higher after passive warm-up compared with active warm-up performed in either thermoneutral (P = 0.03) or in hot conditions (P = 0.02). Results suggest that the main benefits of warm-up for first sprint performance are derived from temperature-related effects. Active warm-up did not impair prolonged intermittent-sprint performance in the heat compared with thermoneutral conditions.     

FRFT-OFDM系统联合同步算法

研究OFDM系统中的同步问题,通过对LFM信号在分数阶傅里叶域能量汇聚性的分析,提出一种基于FRFT的具有较低复杂度的联合载波频率、采样频率以及符号定时的同步算法.该算法在分数阶傅里叶域对由插入到OFDM符号中的LFM信号所产生的对称点进行搜索,结合FRFT的时移、相移以及分数阶卷积等性质,对3种偏差进行估计.仿真结果表明,该算法的性能随LFM信号长度的增加而提高,且优于其他同类算法.
