Flaviviruses are positive-sense RNA viruses, and many are important human pathogens. Nonstructural protein 2B and 3 of the flaviviruses(NS2BNS3) form an endoplasmic reticulum(ER) membrane-associated hetero-dimeric complex through the NS2B transmembrane region. The NS2BNS3 complex is multifunctional. The N-terminal region of NS3, and its cofactor NS2B fold into a protease that is responsible for viral polyprotein processing, and the C-terminal domain of NS3 possesses NTPase/RNA helicase activities and is involved in viral RNA replication and virus particle formation. In addition, NS2BNS3 complex has also been shown to modulate viral pathogenesis and the host immune response. Because of the essential functions that the NS2BNS3 complex plays in the flavivirus life cycle, it is an attractive target for antiviral development. This review focuses on the recent biochemical and structural advances of NS2BNS3 and provides a brief update on the current status of drug development targeting this viral protein complex.

缅甸学生认知汉语国俗词语的偏误分析——以动物词国俗词语为例

作者： wint THU HLAING（吴荣荣）上海外国语大学

虽然中国和缅甸同处亚洲,两国之间的经济文化交流源远流长,两国人民的思想与价值观念看似有很多的相同点,但是,动物词国俗词语在汉语和缅甸语中都具有各自丰富而独特的文化涵义,而且存在较显著的语义联想差异。因此,国俗词语也是对缅汉... 详细信息

虽然中国和缅甸同处亚洲,两国之间的经济文化交流源远流长,两国人民的思想与价值观念看似有很多的相同点,但是,动物词国俗词语在汉语和缅甸语中都具有各自丰富而独特的文化涵义,而且存在较显著的语义联想差异。因此,国俗词语也是对缅汉语教学的重要组成部分。本文综合了前人研究成果筛选出6种常拿来作喻体的动物,即马、牛、龙、狗、老虎、鸡,并针对这些动物在汉缅两种语言中的象征意义进行了对比分析。在此基础上,本文从《汉语国俗词典》中,选取出145个相关的典型而又具有代表性的动物词国俗词语,采用问卷调查的方法来了解汉语水平达到HSK5级的缅甸汉语学习者对于汉语动物词国俗词语的学习与认知情况,并发现出现偏误的类型主要可分为国俗语义混淆、国俗语义遗漏及国俗语义误代等三种类型,进而从语际和语内两个角度探析偏误产生的原因。最后从创造语言使用环境、提高学生的学习兴趣、提高教师的教学效率、弥补教材的不足等四个方面提出了相应的教学建议,并运用迁移理论,整理出适用于实际教学的动物词国俗词语汉缅典型使用语境对照表,以供不懂缅甸语的汉语教师参考,从而帮助缅甸学生切实加强对汉语动物词国俗词语掌握,切实提高其使用汉语进行跨文化交际的能力。

The n-type semiconducting titanium oxide thin films are well-known as electron transporting interlayer in photovoltaic cells. The favorable characteristics of interlayers in photovoltaics are high optical transmittance （T%）, wide band gap energy （Eg） and high electrical conductivity （σ）. Modifying titanium oxide films with metal nanoparticles would increase electrical conductivity but reduce optical band gap energy. We developed the sol-gel derived titanium suboxide （TiOx） films modified with silver （Ag） or gold （Au） or copper （Cu） nanoparticles （NPs）. This study explores a tradeoff between narrowing optical band gap and enhancing electrical conductivity of nanostructured TiOx films by controlling the Au- or Ag- or Cu-NPs loading concentrations （mol%） in titania. The Au- and Cu-NPs loading concentration of 4 mol% should meet a tradeoff which yields the higher T%, wider Eg and higher compared to those of pure TiOx films. In addition, since the pure Cu is not thermodynamically stable in ambience as compared to Au and Ag, the stability of as-obtained colloidal CuNPs is also examined. A careful examination of the time evolution of surface plasmon resonance （SPR） bands of CuNPs indicates that their stability is only up to 4 h.

The DSSCs (Dye-sensitized solar cells) with photoanode using different sizes of particulate TiO2 (18 nm, 30 nm and 200 nm) have been fabricated. The synthetic organic dyes (LEG4) was used as photosensitizer. The present work mainly investigates the influence of TiO2 photoanode modification on light absorption, charge transport and carrier recombination which are then correlated to the device efficiency measured under AM1.5 solar irradiance. The DSSCs with photoanode using larger 200-nm-TiO2 as light scatterer outperform other devices without larger TiO2. It is attributed to an increase in harvesting photons (by UV-vis spectroscopic measurement) via light scattering, smaller ideality factor (by dark current analysis), thus lower recombination possibility, lower charge transfer resistance and longer electron lifetime (by electrochemical impedance spectroscopy) which results in longer electron diffusion and higher charge collection efficiency. The photoanode modification in DSSCs has a strong impact on optical and charge transport properties, and eventually on the photovoltaic performance.

随着中缅合作的日益增多,中缅关系也在不断升温。近年来缅甸政府对于缅甸私立学校特别是中文学校持有明显的开放态度。从国际中文教育发展的角度来看,一种语言在当地的发展,需要依托所在国的语言政策以及当地政府对这种语言教学的态度,因此从这个大背景下研究缅甸中文学校的现状,有助于缅甸中文教学顺应缅甸语言政策的形势,从而有利于缅甸中文教学的推广,与此同时也可以对缅甸的政治、历史、社会、文化等有一个全面了解,这也符合当前社会对国际中文教师应具备多元文化意识及了解他国文化的要求。仰光作为缅甸最大城市,无论是在经济上,还是在教育资源上,都要优于缅甸其余城市,不过仰光民间中文学校在“三教”问题上,如教师培训、师资力量、中文教材的选用及教师的教法等,却要比缅甸其他市弱一些,这也正是本文希望了解的问题,基于此,论文围绕仰光民间中文学校的师资、薪资、培训、教材的选用、教师对教材的满意度、教师课堂上采用的教学方法等展开,分别调查了仰光福星孔子课堂、仰光庆福宫佛学苑、仰光明德中文学校,在对这三所学校教师的调查、访谈(围绕调查问卷)的基础上,结合语言管理、语言政策相关理论,采用定量分析的方法,对缅甸仰光民间中文学校进行重新审视和分析。论文由四个部分组成:第一部分为绪论(研究背景、意义、综述及研究设计)。第二部分介绍缅甸不同时期的语言政策和中文学校的发展,概括了缅甸五个时期(封建王朝、英属殖民、吴努政府、奈温政府、现政府时期)下的中文学校。第三部分是在缅甸语言政策背景下,仰光地区中文教学现状调查。总共分为三节:第一节介绍了调查的对象、目的与方法,第二节介绍了本次调查的三所学校,第三节是根据调查,结合缅甸语言政策背景,经过分析发现,缅甸的中文教学(包括民间中文学校),最大的问题是还没有被缅甸政府纳入国民教育体制,因此缺乏政策的支持。本文尝试以“三教”为切入点,对缅甸仰光民间中文学校进行探析,最终得出在教师方面:缺少了政府的财力支持、工资保障、师资力量、针对教师培训及考核存在问题等。教材方面,由于缺少资金,因此教材的选用受到限制,其次,教材选用体现出“自上而下”决定的特征。教法方面,教师大多使用翻译法、其次是“听说法”和“交际法”,针对汉字书写难点,教师采用“讲授法”和“练习法”等,此外教师还会根据学生的测试和评估成绩,对教学内容和教学方法做出适当调整,因此呈现出灵活性。但从课堂管理及教案规范性等方面,教师则呈现出随意性。第四部分是在第三部分的基础上,借鉴“语言管理”的研究成果和理念,对缅甸语言政策背景下针对仰光民间中文学校进行思考,最后得出,中文在家庭域和学校域的语言管理方面呈现包容性,在公共域方面,目前还存在不足,其中在影响语言教育政策因素方面,中文在缅甸国家的语言意识形态上,呈现出良好的趋势,而在语言社会状况的人口结构和教育制度上,呈现不足。

在油藏特性和油藏的开发优化中，裂缝方位对于确定倾斜构造是关键的一步。电缆交叉偶极子测井测量横波速度的各向异性，它成为井倾斜测量和九分量垂直地震剖面测井的替代品，价格相对便宜。对加旦福尼亚的威尔士油田浅层的中新世硅质岩油藏开展了多井研究（产油５００多万桶），此项研究的目的是绘制预测诱导缝方位变化图。各向异性数据结果表明：由各向异性测井预测的方位与垂直地震剖面（ＶＳＰ）所得的一致。
