Study of SnO_x doped with Cu as negative electrode material for micro thin film Li-ion battery

研究了掺杂Cu的Sn的氧化物薄膜,它可以作为微型薄膜锂电池负极材料。这种薄膜是采用磁控溅射的方式,在硅基底上沉积了SnOX和金属Cu。Xrd分析和SEM观察表明:随着金属Cu掺杂量的增加,所制备薄膜由晶态趋向于非晶态,有利于锂离子的嵌入与脱出。恒电流充放电测试表明:随着金属Cu掺杂量的增加,SnOX薄膜放电容量有所增加,循环性能有很大的提高。这种掺杂Cu的SnOX薄膜的制备方法可用于微型薄膜锂离子电池。SnOx thin films doped with Cu as negative electrode for micro thin film Li-ion battery are studied.SnOx thin films use magnetron sputtering mode SnOx and Cu are deposited on Si substrate.The XRD analysis and SEM observation show that phase of thin oxide thin films tends from crystalline to amorphous with the increase of doping amount of Cu,which helps Li-ion to implant and abjection.Constant current charge and discharge tests show that with the increase of doping amount of Cu,the discharge capacity of SnOx films is increased and cycle performance is greatly improved.The method of fabrication of SnOx thin film doped with Cu can be used for micro thin film Li-ion microbatteries.国家自然科学基金资助项目(60976082;60936003); 航空科学基金资助项目(2008ZH68002

基于空间感知的旅游城市居民游憩忠诚度前因关系研究

公共游憩空间是承载居民日常游憩的主要空间,度量居民对公共游憩空间的忠诚度对改善居民游憩品质具有重要意义。该文以厦门城市居民为实证研究对象,以游憩环境感知与空间感知为潜变量,以游憩满意度为中介变量,通过结构方程模型方法验证、构建旅游城市居民游憩忠诚度前因关系模型。研究结果表明:(1)空间感知对游憩满意度具有正向显著的影响;(2)游憩满意度对游憩忠诚度具有正向显著的影响,且游憩满意度对空间感知和游憩忠诚度的影响关系具有正向显著的中介调节效果;(3)游憩环境感知与游憩忠诚度无显著的直接相关性,但可通过游憩满意度对游憩忠诚度产生间接影响。文章将空间感知引入游憩忠诚度的前因关系模型,在理论上完善了游憩忠诚度形成的动力机制,可作为旅游城市居民政策制定的参考依据。厦门市社会调查项目“厦门市公共游憩空间服务承载力研究”资助~

闽江下游及河口溶解无机氮的季节分布及组成

为研究闽江下游及河口区溶解无机氮（DIN）的季节分布及组成,采集并分析了四季的表层水样。平面分布上,NO3-N不同季节有所不同;NH4-N及NO2-N不同季节分布特征基本一致,仓山区、鼓楼区附近的站位受城市污水影响而含量偏高。季节变化上,NO3-N南北段春季最高,河口段冬季最高;NH4-N南北段秋季远高于其它三个季节,河口段季节变化不大;NO2-N南北段及河口段季节变化不大。DIN组成上,南北段不同季节占比相似,DIN组成上未达到热力学平衡;河口段DIN组成季节变化不大,三态间基本达到热力学平衡。DIN[2]转化上,北段三氮之间相关性总体较弱,且与DO的相关性变化较大,三氮关系受复杂的来源、人类活动及生物化学过程影响;南段三氮之间的相关性较显著也较复杂;河口段三氮及DO之间的关系季节差异比较明显。此外,闽江下游及河口DIN年际增高及超标现象较严重。国家自然科学基金(41376050

试谈汉文化对越南文学的影响

中国汉文化对越南有着多方面的影响,越南顶尖作家阮攸的扛鼎之作——《金云翘传》是汉文学孕育的结果.从瞿佑的《剪灯新话》和阮屿的《传奇漫录》的创作中可以看到在文化和文学的交流和吸收中普遍存在着“误读”的现象

The Measurement of Instrumentalism and the Definition of National Identity——A Theoretical Thinking Provoked by the Founding of a "She" Minority Village

族群理论中的工具论认为,人是理性的动物,无时不在算计和优化自己的利益,族群认同的根本原因就在于政治、经济等方面利益的推动。但是,工具论同时也不否认族籍、传统等对人们具有感召力。本文依据对一个畲族乡的调查指出,在我国的民族政策和特殊国情下,即便没有族籍(无论是生物学意义上的还是文化意义上的)和传统的存在,只要有工具主义的好处,某些特定的人群也可能借用其他族群的族籍,来构建出一个新的同时包含不同族群的民族认同。Based on an investigation of a "she" minority village, this article points out that, under our national policy and special conditions, a certain human group can construct a new national identification but include different minorities without even national identity or tradition but the benefits of instrumentalism

Structural Analysis of Disk Micromechanical Resonator

运用AnSyS对圆盘谐振器的结构进行有限元分析,并结合集总参数模型,确定了圆盘谐振器锚点尺寸与位置对圆盘谐振器性能的影响,包括谐振频率,振幅与品质因子(Q).在此基础上,提出了一种在圆盘谐振器高阶模式的节点环处做锚点的方案,不仅可以使圆盘谐振器工作在更高的谐振频率,同时也降低了微加工精度的要求.Finite element method(FEM) in ANSYS is used to analyze the structure of disk micromechanical resonator.Especially,FEM combined with the lumped parameter model,are used to study effect of size and position of the disk micromechanical resonator on its vibration amplitude,frequency and quality factor Q.The results show that the size and position of the anchor of the disk micromechanical resonator can greatly affect its performance.Based on these studies,a new disk micromechanical resonator is proposed.It works in higher order vibration mode and takes nodal circle of the mode shape instead of the disk center as anchor.With this improvement,the disk micromechanical resonator can be even more easily fabricated since the anchor effect is greatly weakened,which leads to lower precision requirements on microfabrication.航空科学基金项目(2008ZH68002
