通过历史论证与理论推演,旨在探索现代足球战术在后现代化社会背景下的发展新趋势,结果表明,现代足球战术经历100多年发展,已形成整体攻守平衡的战术体系结构。但问题也表明,这个高度优化结构存在着敏感的缺陷与突变的可能性,人们对攻守平衡的盲目优越感阻碍了战术认识的进一步深化;现代足球战术体系的高度发展已酝酿着大量向后现代化过渡的特征,后现代条件下非平衡化与个体化元素日益显现;nX自由人战术体系的提出,旨在突破现代足球攻守平衡体系结构,使足球战术自组织变革成为可能,是足球制胜因素的新发现。

中点电压平衡问题是二极管钳位式三电平逆变器的固有问题,本文对此进行了深入探讨,分析了中点电压失衡的原因,从载波的角度研究了载波幅值变化对中点电压的影响,推导出中点电压波动和调制比、调节量、功率因数之间的关系,讨论了调节量、功率因数对中点电压波动的影响,提出了一种基于载波变幅的SPWM调制策略,通过保持调制波不变,改变载波的幅值来实现中点电压平衡控制。最后在基于DSP的二极管钳位型三电平逆变器试验平台上验证了上述调制方案的有效性。

The blend morphology and vertical arrangement are critical to the performance of organic bulk-heterojunction photovoltaic *** the present paper,the authors proposed a new annealing method that controls the blend morphology and vertical arrangement of two materials by means of simultaneously applying external electrical field and violet irradiation on the active layer of poly(3-hexylthiophene) (P3HT) and -phenyl C61-butyric acid methyl ester(PCBM) during annealing *** using this annealing method,the power conversion efficiency increased by 36%,which was caused by vertical phased-separated blend of crystalline P3HT and PCBM and better charge extraction of electrodes.X-ray photoelectron spectroscopy(XPS) was measured to prove more fullerene derivatives at the organic/cathode interfaces by using this annealing *** X-ray diffraction(XRD) analysis and UV-Vis absorption spectrum analysis also revealed more ordered polymer crystallization.

人们患有难以治愈的疾病,需要用医学的手段进行人体器官移植,已经超越了社会个体的自我控制能力,只能通过社会努力与国家尽其义务才能加以避免和控制。通过对美国、西班牙、欧盟、日本、伊朗和苏联等国家和地区的国家义务模式进行比较分析,得出在国家义务视野下保障患者器官移植权的实现,应在履行最基本性、比例合理性、特例特办性、物质制约性及伦理性的基本范围内,在坚持人权均衡保护原则、国家义务合理履行原则及国家义务主导地位原则的基础上,确定国家义务在器官移植法律关系中具体角色定位,在依法获得国家的帮助下,真正保障患者器官移植需要的完成,实现人们的生命健康权。
