Fabrication and Doping of Freestanding Si-O-C Composite Films by Precursor Method and Their Application in LED Devices Packaging

LED作为第四代光源，因其尺寸小、响应快、亮度高、节能环保等诸多优点展现出较广阔的应用前景。LED向着高功率、高密度封装的方向发展，散热问题至关重要，散热效果差导致芯片结温过高、荧光粉量子产率降低、发光波长偏移及器件老化等问题。大功率LED散热主要集中在封装材料的研究、热界面材料的选择、封装结构的合理设计及冷却系统的优化等方面。而散热基板作为其重要封装材料，要求具有高绝缘性、高导热性、高平整性以及与芯片衬底匹配的热膨胀系数等特性。因此，本文主要针对封装材料中的高热导散热基板材料进行研究，主要工作如下： 首先，先驱体聚碳硅烷（PCS）经熔融纺膜、氧化交联、高温预烧、高温烧结工艺制得自支撑硅氧碳...Light Emitting Diode (LED) as the fourth generation light source has presented several advantages over traditional light sources such as small size, fast response, high-brightness, long lifetime, energy-saving and environment-friendly.

论多元音乐文化背景下的中学音乐教育

我国系统的中学音乐教育,从学堂乐歌算起,已有100多年的历史,古今中外的文人学者们都撰文对音乐不可替代的美育教育功能作了详细的论述。但随着时代的发展,当今建立在西方教育体系之上的音乐教育也面临着诸多问题,弊端也日显突出。针对这些问题,笔者提出了一些拙见:借鉴国外的音乐教育理念,将多元文化音乐教育和音乐人类学的观念引入中学音乐教育,以培养学生多元文化感;扩大他们的音乐视野;更新他们的音乐观念;培养他们对音乐的兴趣;让他们从文化层面更深入、更全面地了解音乐

Underway observation of surface temperature and salinity in north South China Sea in September 2006

通过2006年9月南海北部开放航次的走航观测,得到了该海区多个断面的表层温度、盐度分布曲线。QuikScat海面风场资料显示观测期间处于西南季风向东北季风的转换阶段,走航观测所得的温、盐资料显示出在这一季风转换的特殊阶段该海区表层的水文特征。珠江口冲淡水的扩散范围在季风转向前后有显著的变化,低盐的冲淡水在西南季风阶段向珠江口外海区的东南方延伸较远,而在东北季风阶段则受珠江径流量、南海北部表层环流等因素的影响收缩至珠江口附近。闽南近岸和台湾浅滩南部表层具有低温高盐特征,但CTD资料表明台湾浅滩区域存在上升流,结合风场资料,可证实观测期间此处的上升流由海流-地形因素所造成。Based on the underway observation data of Joint Survey of Northern South China Sea in September 2006,the distributions of surface temperature and salinity along several sections were obtained.The sea surface wind field data from QuikScat indicated that September was the conversion period from southwest wind to northeast wind in 2006,and the temperature and salinity data obtained from the underway observation could give a clear demonstration of the hydrological character of the northern South China Sea during this special period.The extension of diluted water near the estuary of Zhujiang River had a major change after the monsoon conversion.During the phase of southwest monsoon,the diluted water could extend to the southeast to a larger distance;while the diluted water was confined to the nearby area of the estuary in the northeast monsoon.In the inshore area off south Fujian and southern part of Taiwan Bank there existed cold and high salinity waters.It was proved by the CTD data that an upwelling was active in the southern part of Taiwan Bank.Considering the northeast monsoon,it could be confirmed that this upwelling was driven by the current-topography effect.国家自然科学基金项目(40576015,40521003,40576013

Musical Expertise Has Minimal Impact on Dual Task Performance

Studies investigating effect of practice on dual task performance have yielded conflicting findings, thus supporting different theoretical accounts about the organisation of attentional resources when tasks are performed simultaneously. Because practice has been proven to reduce the demand of attention for the trained task, the impact of long-lasting training on one task is an ideal way to better understand the mechanisms underlying dual task decline in performance. Our study compared performance during dual task execution in expert musicians compared to controls with little if any musical experience. Participants performed a music recognition task and a visuo-spatial task separately (single task) or simultaneously (dual task). Both groups showed a significant but similar performance decline during dual tasks. In addition, the two groups showed a similar decline of dual task performance during encoding and retrieval of the musical information, mainly attributed to a decline in sensitivity. Our results suggest that attention during dual tasks is similarly distributed by expert and non-experts. These findings are in line with previous studies showing a lack of sensitivity to difficulty and lack of practice effect during dual tasks, supporting the idea that different tasks may rely on different and not-sharable attentional resources

Application of Oxalyl Dihydrazide in the Combustion Synthesis of LaAlO_3

通过金属硝酸盐和草酸二酰肼氧化还原的混合物燃烧方法合成了钙钛矿型lAAlO3粉末。混合物在350℃着火燃烧后产物为非晶态,进一步在500℃和600℃焙烧后得到单相结晶钙钛矿相。混合物的dSC分析得知,混合物的着火起始温度为340℃。这种软化学方法的应用使钙钛矿型lAAlO3的合成温度达到了迄今为止的最低温度。The LaAlO 3 Fine powder with perovskite structure has been synthesized by the combustion of redox mixture containing corresponding stoichiometric amount of metal nitrate, La(NO 3) 3·6H 2O and Al(NO 3) 3·9H 2O,and oxalyl dihydrazide, C 2H 6N 4O 2 at 350℃.The powder combustion product was amorphous.It could yields crystalline single phase perovskite aFter being calcined at 500℃ and 600℃.DSC analysis on the mixture shows that the process of combustion starts at 340℃.The application of such socalled soft chemistry method has reached the so Far lowest synthetic temperature of the perovskite type LaAlO 3.福建省自然科学基金;国家教委回国科研基
