中日经济相互依赖的敏感性与脆弱性分析

本文运用权力与相互依赖理论,分析中日经济相互依赖关系中的敏感性与脆弱性,以及由此产生的权力问题。中日经贸关系表面上看两国互为重要贸易伙伴,似乎是对称性相互依赖,但本文通过分析认为,实质上中日贸易关系是一种非对称性的相互依赖。中国在相互依赖中具有“敏感性“,但不具有“脆弱性“。日本在敏感性相互依赖中获得了一定的政治影响力。基于以上认识,本文最后就中日经贸合作如何摆脱“敏感性“非对称相互依赖,向“对称性“方向发展,提出了自己的政策建议

Preparation of BaTiO3 Nanoparticles with Various Particle Sizes and Ferroelectic and Dielectric Properties of 0-3 Type BaTiO3/PVDF Piezoelectric Composite Materials

铁电材料作为一种应用广泛的功能材料，一直以来都受到广泛的关注。随着科技的发展，对铁电组件小型化、集成化的要求越来越高，这就进一步要求作为原料的铁电体晶粒尺寸不断减小。当晶粒尺寸减小时，铁电体的铁电性是否还能保持是一个重要的问题，对这种尺寸效应的研究具有重要的意义。由于钛酸钡(BaTiO3)晶体结构简单并具有高介电常数，在理论上和实践方面研究BaTiO3的的临界尺寸很有意义。本论文采用BaTiO3作为增强材料，压电聚合物聚偏二氟乙烯(PVDF)作为基体，用制备压电复合材料的方法研究钛酸钡纳米颗粒的尺寸效应。压电聚合物基压电复合材料兼具压电陶瓷和聚合物的优点，而且还可以表现出复合材料的新性能，所以...Ferroelectric materials, which are widely used as functional matrials, have been extensively investigated recently for device applications. However, ferroelectric devies should be miniaturized and integrated with the development of nanotechnology, nanoparticles then should be handled and utilized. Whether the ferroelectricity still maitain when the grain size decreases, is the biggest obstacle in ...学位：理学硕士院系专业：化学化工学院化学系_物理化学(含化学物理)学号：2052006115197

環境刺激によるマウスの情動・不安・学習行動への影響

Environmental stimulation affects humam. We studied the effect of environmental noise to prenatal or early postnatal period on the development of mice emotional and anxiety-related behavior and the spatial learning in mice. Present results indicated that environmental noise to early postnatal period might cause learning impairment accompanied by the emotional and anxiety disorder afterwards. In the other study, the effect of (Z)-3-hexenol, one of the main constituent of green odor, on the anxiety-related behavior of mouse in an elevated plus-maze and the content of 5-hydroxytryptamine (5-HT) and its metabolite in the brain were investigated. Changes in serotonergic activity in the cortex and hippocampus were suggested to be involved in the anxiolytic effect of (Z)-3-hexenol observed in the elevated plus-maze test

Optimization Electrode of GaN-Based Light-Emitting Diode

针对以蓝宝石为衬底的GaN基发光二极管出现的电流扩展不均的问题,采用有限元方法建立了GaN基发光二极管的三维网络模型,并对四种常见结构的器件进行数值模拟,发现影响二极管电流的因素不仅与发光二极管电极的位置有关,而且依赖于器件的结构参数。以电流扩展不均为指标确定出这四种器件中最佳的电极位置分布,同时对最佳电极位置分布的器件进行了结构参数优化,结果表明当p型金属层方块电阻与n型GaN的方块电阻接近时,电流扩展均匀性最好,且p-GaN的接触电阻和厚度越小,电流扩展越不均匀。A 3D networks model of GaN-based LED on sapphire substrate was built by finite element analysis to simulate the non-uniformity current spreading.Analog modeling was done on the four normal device structures,it was found that the factors effected the current of LED were the position of electrode and the parameters of device structure.Considering the practical structures of GaN-based LED,four LED designs were modeled and the optimal electrode distribution was obtained,meanwhile the structure parameters were optimized.It reveals that the smaller contact resistances and the thickness of p-GaN are,the more non-uniformity of current distribution is.国家自然科学基金(60276029);; 国家863计划(2004AA311020和2006AA032409);; 福建省科技项目和基金(2006H0092,A0210006,2005HZ1018
