The Research of Chinese TV Documentary Films Creation——A Case Study of The Long March

文献纪录片，是国家和民族的影像日志，在传承历史文化和构建主流意识形态方面都发挥了重要的作用。至今，文献纪录片的数量在不断的增加，但真正叫好又叫收视率的文献纪录片精品还远远不够，且很难走出国门。在这样的环境下，创作者需要思考怎样打造具有核心竞争力的文献纪录片，让其在各种文化融合的冲击下脱颖而出。 《长征》是纪念长征题材最重要和最具水准的“现象级”的文献纪录片，作为本文研究的对象。本文采用电影分析方法论，通过运用影片分析的描述性、引述性和资料性三种工具来对其主题挖掘、叙事手法、镜头语言，以及所包含的思想内涵进行分析和解读，探究其成功之处，从而总结《长征》对文献纪录片创作的一些启示。 文...As an important type of documentary, documentary films play an important role in the inheritance of national culture and the construction of mainstream ideology. So far, a number of documentary films continue to increase, but the real documentary films boutique is far from enough, and it is difficult to go abroad. In such environment, the creator needs to think about how to build documentary films...学位：文学硕士院系专业：新闻传播学院_新闻学学号：1052014115308

Determination of hydrogen peroxide in food

利用猪血红蛋白(PHb)的催化特性,以3,3',5,5'-四甲基联苯胺(TMb)为底物,建立了一种催化光度终止法测定食品中残留过氧化氢(H2O2)的方法。实验考察了终止剂的类型和浓度、反应时间、PH、温度、TMb浓度对H2O2检测的影响。在选定的反应条件下,体系吸光值与H2O2浓度在1.46x10-6~2.91x10-5MOl/l范围内呈良好的线性关系,线性相关系数为0.9958,方法对H2O2的检出限为5x10-7MOl/l,测定标准偏差为4.9%,样品的加标回收率为92.9%~103%,利用该方法进行了实际样品中的H2O2分析,结果与国标法无显著性差异。A new spectrophotometric method was developed for the determination of hydrogen peroxide(H2O2) in foods using 3,3′,5,5′-tetramethylbenzidine(TMB) as a terminating agent in the catalytic reaction between hemoglobin porcine(pHb) and H2O2.The influence of terminating agents,reaction time,pH,temperature and the concentration of TMB was discussed.Under the optimal experimental conditions,the absorbance value was linearly correlated to H2O2 concentration in the range of 1.46×10-6～2.91×10-5 mol/L with the correlation coefficient of 0.9958.The detection limit was found to be 5×10-7 mol/L and RSD was 4.9 %.The recoveries in the range of 92.9 %～103 % were obtained.The determination results corresponded well with those by the national standard method

叔胺从硫酸盐溶液中萃Fe(Ⅲ)机理的研究

本文报道叔胺(TOA)从硫酸盐介质中萃取Fe(Ⅲ)的机理。研究了萃合物的紫外及红外光谱。根据实验结果提出了萃合物的可能结构形式。认为叔胺只能萃取部分水解的Fe(Ⅲ),而伯、仲胺既能萃取水解形式的Fe(Ⅲ)也能萃取非水解形式的Fe(Ⅲ),不同的条件下两种机理可以同时进行或相互转变。讨论了三类胺萃取Fe(Ⅲ)及硫酸反萃取Fe(Ⅲ)的性能的差别

The present situation and developmental direction of fishery feed industry in Fujian Province

当前的福建省渔用饲料工业正处在稳定发展阶段,安全、卫生、符合无公害生态要求已成为衡量饲料行业健康发展的重要指标。该文阐述了福建渔用饲料工业的现状,指出存在的问题,阐明渔用饲料科技发展方向。The development of fishery feed industry in Fujian Province is on the stable developmental period at present. The safety and hygiene of the feed should accord with the requirement of no-pollution ecology, and which have become the important indicator in the healthy development of fishery feed industry. This paper expounded the present situation, existent problem and developmental direction of science and technology about fishery feed industry in Fujian Province.国家863计划项目(2002AA603013);; 厦门大学预研项目(2004Y50702);; 厦门大学高层次人才引进科研启动项目“锯缘青蟹营养需求及其免疫营养研究”(2005

肟类萃取洁霉素的研究

本文首次将肟类萃取剂用于洁霉素的萃取，研究了其萃取规律.在中性及弱碱性条件下，所选用的氧肟－84、酮肟－85及N510三种肟类均可有效地萃取洁霉素，且在酸性条件下容易反萃.无论氧肟还是酮肟均按溶剂化历程萃取洁霉素，前者形成L.S型萃合物，后者形成L.2S型萃取合物（L－洁霉素，S－肟类萃取剂）

掺镨GaN薄膜的微结构与光致发光

利用背散射／沟道（RBS／C）技术、原子力显微镜（AFM）和光致发光（PL）谱研究了掺镨GaN薄膜的微结构和可见光发光特性。RBS／C结果表明，注入Pr后，在注入层引入了晶格损伤；注入样品经1050℃退火后，部分损伤得到恢复，但是晶体质量没有恢复到注入前的状态。AFM结果表明，注入Pr后，表面凹凸不平，而且在注入区引起了膨胀，膨胀幅度达到23．368nm左右。PL结果表明，在850—1050℃退火，发光强度按e指数增加；当退火温度达到1050℃，发光强度最强，经过数据拟合可得Pr^3＋的热激活能为5．8eV
