    目前,国际汉语教师数量初具规模,质量提升迫在眉睫。国际汉语教师教育、专业素质、专业意识、专业能力和队伍建设研究较为成熟,但教师个体专业情意、专业发展途径和目标亟需关注。国际汉语教师选拔、培训、派出和评价等实践活动尚缺乏理论支撑。新的形势需要我们对优秀汉语教师进行研究。 本文“以学习者为中心”,前后共调查40多个国家的600余位来华汉语学习者,分别从学习者心理发展因素(年龄、性别)、社会文化背景(国籍、母语、是否华裔)、学习经历(汉学习时长、汉语水平)、情感因素(焦虑)、认知因素(学习动机、学习态度、努力程度、学习策略、学习风格)五个方面探讨不同学习者期待的优秀汉语教师个性要素和教学要素。这也...At present, the international Chinese language teachers are beginning to take shape and it’s quite urgent to improve their professionalism. The research on training education, professional quality, professional consciousness, professional competence and teaching staff of the international Chinese language teachers has become more and more abundant, but the research on their professional affection,...学位:文学博士院系专业:人文学院_汉语言文字学学号:1022010015385

    在光照培养箱中人工对照培养小扭口藓(Barbulaindica(Hook. )Spreng)的芽胞,显微镜下观察并记录其发育成配子体的全过程。结果表明:小扭口藓芽胞在3 ~4d即可萌发; 10d左右开始分化出绿丝体、轴丝体及假根; 18d,轴丝体上的侧枝顶端细胞以分生缢割的方式产生单细胞或多细胞芽胞; 40d,轴丝体上开始出现配子体原始细胞;之后,配子体原始细胞发育成桑椹状的幼小配子体。还对芽胞形态发育、生理生态及配子体发生过程的特点进行了分析和讨论。,CN 23-1480/

    The Study about Integrity of Marking Parts of Speech

    内容提要 目前,在辞书中全面标注词性是当今我国语文辞书编撰的一大趋势。本文利用数据库技术,通过统计和对比,采用定量与定性相结合的方法,从辞书词性标注和义系完整性这个角度来展开的,而义系完整性在辞书中主要体现为一个词的义项概括的完整与否。 我国语文辞书词性标注走过了一个由尝试标注--有意识部分标注--全面系统标注词性的艰难历程。在语文辞书里标注词性有着重要的意义和必要性。但在实践中,却遇到了如词类的划分、词与非词的区分、词的兼类等一些难以一时克服的问题。本文通过对比分析《现代汉语规范字典》和《现代汉语词典》中已经标注数词和量词的条目,认为一部辞书要想真正地逼近现代汉语,使词性标注和义项划...Abstract In contemporary Chinese dictionary compilation, it is generally tended to completely mark the parts of speech, whereas a lot of problems keep arising in this field. By resorting to database the present thesis mainly deals with the parts of speech and integrated levels of semantic meaning in dictionaries. The quantitative and qualitative ways are applied.

    Research on Cost Management in the Lean Production Model --Based on C Corporation

    随着经济全球化的发展,企业竞争环境日益激烈,对制造商在成本、质量方面提出了更为严格的要求,即质量要比竞争对手的好,成本要比竞争对手低,只有这样才能在市场中占据高点,但成本与质量是一对矛盾。片面强调低成本可能导致忽略产品质量和新产品研发,从而削弱企业可持续发展的能力;片面强调产品质量则可能因成本失控而导致企业陷入财务危机。因此,任何企业都需要在降低成本与提高质量之间寻求某种平衡。旨在消除浪费、降低成本和持续改进质量的精益思想,为实现这一目标提供了可能。 论文以C公司为案例,从精益设计、精益采购、精益生产、精益物流和精益客户服务五个方面,分析和总结了精益成本管理的指导思想、业务流程和成效。文章认...Abstract With the development of the economic globalization, nowadays almost enterprises will get more and more competitive environment. It has brought forward a stringent requirement to the manufacturers in the cost and quality aspect. That is our production must get better quality and lower cost than our competitors, which is the only way to occupy bigger market. However, cost and quality is a ...学位:会计硕士院系专业:管理学院会计系_会计硕士(MPACC)学号:X200515707

    利用水下饱和脉冲调制叶绿素荧光仪(dIVIng-PAM)测定了珊瑚养殖水处理中3种常见大型海藻石莼(ulVA lACTuCA)、条浒苔(EnTErOMOrPHA ClATHrATA)和羽状蕨藻(CAulErPA MEXICAnA)光能转化效率(fV/fM),快速光曲线(rlC)相关参数和非光化学淬灭(nPQ)。结果表明:石莼和条浒苔的fV/fM分别为0.808±0.004和0.816±0.009,显著高于羽状蕨藻。最大相对电子传递速率rETrMAX(17.52±2.92和19.59±4.43μMOl E·M-2·S-1)、半饱和光强Ik(53.41±8.18和59.71±13.52μMOl PHOTOnS·M-2·S-1)也明显高于羽状蕨藻(rETrMAX和Ik分别为13.72±5.41μMOl E·M-2·S-1和32.67±14.06μMOl PHOTOnS·M-2·S-1),表明石莼和条浒苔有着比羽状蕨藻更高的光合能力和对强光的耐受能力,光保护能力更强;羽状蕨藻较高的rlC初始斜率α表明其在弱光下拥有更强的光捕获能力,弱光下光合效率更高;随光照的增强(0~373μMOl PHOTOnS·M-2·S-1),羽状蕨藻nPQ的增幅有限(0~0.2),最大值仅为条浒苔和石莼的38.1%和62.5%,表明这种藻类更容易受到强光的抑制。因此,在珊瑚养殖的水处理中,可以根据不同的光照选择适宜的藻种或藻种组合并根据光梯度进行布局,反之也可以根据藻种来选择合适的光源,以达到最佳的处理效率。This study investigated the difference of photosynthetic capacity in three macroalgae species( Ulva lactuca,Enteromorpha clathrata,and Caulerpa mexicana) commonly used for nutrient removal in coral aquariums.The photochemical efficiency( Fv/Fm),parameters relevant to rapid light curve( RLC) and non-photochemical quenching( NPQ) in the macroalgae were measured by underwater saturation pulse modulated chlorophyll fluorometer( Diving-PAM).The results showed that Fv/Fmwas 0.808 ± 0.004 for U.lactuca and 0.816 ± 0.009 for E.clathrata,which were higher than that for C.mexicana.Higher maximum relative electron transfer rates( rETRmax)( 17.52 ±2.92 and 19.59 ±4.43 μmol e·m- 2·s- 1) and half-starved value of light intensities( Ik)( 53.41 ±8.18 and 59.71 ±13.52 μmol photons·m- 2·s- 1) were observed in U.lactuca and E.clathrata than that in C.mexicana( 13.72 ± 5.41 μmol e·m- 2·s- 1for rETRmaxand 32.67 ± 14.06 μmol photons·m- 2·s- 1for Ik),indicating that U.lactuca and E.clathrata have stronger photosynthetic capacities,photo-protection capacities and tolerance to higher intense light than C.mexicana.A significantly lower RLC initial slope α in C.mexicana implied that this algal species has a higher photosynthetic capacity under weak light condition.With increasing the light intensity( 0- 373 μmol photons·m- 2·s- 1),however,C.mexicana had a limited increase of NPQ( 0- 0.2),the maximum of which was equivalent to 38.1% of that in U.lactuca and 62.5% of that in E.clathrata.These results indicate that the photosynthesis of E.clathrata may be more easily limited by intense light.Our study suggests that the selection of algal species for nutrient removal in a coral aquarium should be adapted to the light intensity.Single species or the combination of different species of macroalgae can be selected according to the illumination of the coral aquarium in order to maximize the efficiency of nutrient removal.国家海洋局第三海洋研究所基本科研业务项目(海三科2011033); 厦门海洋研究开发院共建项目; 海洋公益性行业科研项目(201105012)资

    “真”是中国古典美学中的一个重要范畴,目前学术界对它的研究无论从广度和深度来说都显得很不够。本文第一章从纵向梳理了古代文论中的“真”从先秦到元代千年的历程:即先秦儒家的尚“诚”、道家道“法贵天真”,魏晋南北朝时期钟嵘提倡诗歌道“真美”,唐代李白、司空图提倡诗歌的“天真”和妙造自然,宋代苏轼的“意从肺腑出”,金元时期元好问的“真淳”等等,并总结了“真”范畴美学特征:即真理之真、客观真实、本真自然和情感之真等四个方面。第二章重点考察了“真”范畴在明代的流变,并从哲学和美学两方面分析了明代“真”范畴繁荣的原因。第三章和第四章具体分析明代各大家对“真”范畴的论述,尽可能客观具体地反映明代“真”范畴的意...“Truth” is a significant category of the Chinese classical aesthetics.The current study about it in the academic realm is very limited. The first chapter of this article, vertically exploring the evolutional course of the “Truth” in the ancient literary theory, summarizes its four aesthetical features. The second chapter highlights the changes of “Truth” in Ming Dynasty and analyzes the causes of ...学位:文学硕士院系专业:人文学院中文系_文艺学学号:X200510100
