Complementary Analysis on the Trade Between China and Brazil

巴西作为拉美第一大经济体,在很长时间内没有受到足够重视。近年来,中巴双边经贸关系得到快速发展。分析双边经贸发展的现状、潜力及稳定性等问题,对于促进双边经贸的稳健发展具有较强的现实意义。本文从实证角度对上述问题进行分析,得出了中巴两国在经贸方面具有较强的互补性、较大的发展潜力以及双边经贸关系具有较强的稳定性等结论,并对如何促进双边经贸发展提出了相应的政策建议。As the largest economics in Latin America,Brazil has not been paid enough attention to in a long period for some reasons.In recent years,the Sino-Brazil bilateral economic relationship gained rapid developments.The analyses of the bilateral economic relationship's current development,potentiality and stability are of much practical importance to promoting bilateral economic development.This article analyzed the above issues from the angle of positive analyses,and concluded that China and Brazil had many complementarities,potentialities in trade and the bilateral economic relationship was of strong stability.Then the article put forward relevant suggestions to promote the bilateral economic relationship

Lexical Gap in Chinese-English Translation and its Resolution

在汉英翻译中,由于中华文化的一些特有现象在英语中找不到对等词,造成词汇空缺,难以实现语言符合转换和文化转换的和谐统一。翻译时可采用音译法和意译法等翻译方法来实现文化的有效移植。In the process of translation,there are no equivalent words in English because some phenomena are unique of Chinese national culture,thus lexical gap exists,which is different to realize the harmonious unity of language signs and cultural transformation.Transliteration and free translation can be adopted to realize the effective cultural transplantation

产权、环保意识和环境问题

外部性、产权不分是造成环境问题的根源;公众环保意识低、环保产品需求不足而不具有竞争优势,是企业选择污染环境而不是生产环保产品的重要原因,也是环境问题不断恶化的催化剂。为防止环境问题不断恶化,必须采取有力措施界定产权、提高公众环保意识以从根本上解决环境问题

Whether Chinese Firms Prefer the Network of International Division of Labor

嵌入国际分工网络为发展中国家的发展提供了条件,但国内分工网络的发展是决定其在国际分工中地位的重要基础。本文利用中国省级投入产出数据测算发现,自1987年以来,出现了持续的更偏好国际分工网络的趋势,国内区域间分工程度出现了先下降后上升的趋势。计量分析表明,“为出省而进口“胜于“为出口而进口“,但进口因挤出效应而弱化了区域间关联效应;出口增长促进了地区参与国际分工网络,推动了国内分工发展;fdI主导的分工网络抑制了区域间分工,地区gdP水平、技术地位和政府干预也有重要影响。Embedded in the network of international division of labor supports the development of developing countries,but the development of the network of domestic division of labor is vital to determine the status in the international division.Provincial input-output data shows since 1987 domestic firms have preferred the international division,and the degree of domestic division has been a descending trend firstly and then upward.Econometric analysis shows that "importing for outputting to other provinces" outstripped "importing for exporting",but crowding-out effect of importing weakened inter-regional association.Export increasing promotes the regions participating in international division and advances domestic division positively.FDI-oriented division of labor network restrains the inter-regional division.Regional GDP level,technical status and government intervention also has vital functions.国家自然科学基金项目“二元分工网络约束下中国装备制造业自主创新的机制研究”(71103152); 厦门大学国际经济与贸易系教育发展基金项目“中国本土企业自主创新的战略转变:基于国际分工地位的理论、实证与对策”(201112101); 福建省软科学研究科技项目“全球竞争背景下福建装备制造业技术创新战略”(2012R0083)资

海洋现场叶绿素传感器的校准方法初探

采用单一藻种培养液校准海水现场叶绿素传感器,讨论了校准方法及传感器应用在海洋调查中的可行性,结果发现,利用威氏海链藻(Thalassiosira weissflogii)的培养液校准叶绿素传感器,叶绿素浓度与荧光信号线性关系良好,相关系数R2均大于0.995,每次实验的校准斜率误差均小于5%,表明利用藻液校准叶绿素传感器是可行的,具有可重复性。然后利用传感器与荧光分光光度法测量同一系列藻液,t检验法分析表明当叶绿素浓度大于5μg/L时,两种方法无显著差异;当浓度小于5μg/L时存在显著差异,传感器测量结果偏大;可能是高温、光照等影响荧光分光光度法测量结果。就荧光分光光度法而言,叶绿素传感器可以比较准确地评价水体的叶绿素浓度,不仅可以为浮游植物动力学提供依据,还可以为赤潮预警等提供数据支撑

嗜人类T淋巴细胞病毒Ⅰ型核心蛋白P24基因的克隆与表达

目的 从感染HTLV-1的中国患者外周血单核细胞（PBMCs）中扩增编码HTLV-1核心蛋白P24的cDNA,并在大肠杆菌中进行表达。方法 提取感染者PBMCs基因组DNA,应用巢式PCR方法扩增出HTLV-1核心蛋白P24的cDNA并测序,与pGEX-20T载体构建重组质粒,在大肠杆菌BL21中表达,采用ELISA和Westernblot分析重组蛋白活性。结果HTLV-1核心蛋白P24基因序列高度保守,构建重组载体后,在大肠杆菌中表达的重组蛋白,经检测具有较强的抗原活性。结论 成功地表达了HTLV-1型病毒的核心蛋白P24基因,为国产诊断试剂和疫苗的研发打下了基础
