1、1,Abstract 科技论文摘要的写法,Skill Training,2,摘要是以提供文献内容梗概为目的，不加评论和补充解释，简明、准确地记述文献重要内容的短文。一般文章应附中文摘要和英文摘要。摘要应具有独立性和自含性，不应出现图表、冗长的数学公式和非公知公用的符号、缩略语。,基本特性,3,它位于正文之前，中文摘要以200300字为宜,英文摘要通常100-500个单词（100150 words）,英文摘要内容应对照中文摘要进行翻译。由于篇幅有限，必须十分简练，开门见山，直截了当，不使用多余的词或生僻的词，也避免使用冗长的句子。,4,科技论文摘要大致包括三个部分：一、说明论文的主题二、介绍主要

2、内容三、提出结论或建议 科技论文的摘要，在结构上和语言上相当的程式化。,5,摘要分类,根据内容的不同,摘要可分为以下三大类:一是报道性摘要(informative abstract):也称信息型摘要或资料性摘要。其特点是全面、简要地概括论文的目的、方法、主要数据和结论。通常这种摘要可部分地取代阅读全文。,6,二是指示性摘要(indicative abstract):也称为说明性摘要、描述性摘要或论点摘要。一般只用二、三句话概括论文的主题,而不涉及研究的材料、方法、论据和结论,多用于综述、会议报告等。,7,三是报道指示性摘要(informative-indicative abstract):以报

3、道性摘要的形式表述论文中信息价值较高的部分,以指示性摘要的形式表述其余部分。,8,此外,目前大多数刊物倡导结构式摘要(structured abstract),即报道性摘要的结构化表达,在内容上大致包括目的(Objective)、设计(Design)、地点(Setting)、对象(participants or subjects)、处理(Interventions)、主要测定项目(Main outcome measures)、结果(Results)、结论(Conclusion)等主要方面,强调论文摘要应含有较多的信息量。与非结构式摘要相比,全结构式摘要观点更明确,信息量更大,更符合计算机数据库

4、的建立和使用要求。,9,据统计，目前世界上约有60的核心生物医学期刊采用结构式摘要，但此种摘要不适合综述之类的文章。摘要的要素包括目的（objective）、方法（methods）、结果（results）和结论（conclusion）四部分。,10,结构式摘要的书写方法,目的（What I want to do?）：应简要说明研究的目的和意义，一般用1-2句话简要说明即可，不必太过冗长。目的部分的文字最好不是对文题的简单重复。1）Eliminate or minimize background information2）Avoid repeating the title or part of

5、the title in the first sentence of the abstract.,11,常用英文表达方式英文常以动词不定式“To+动词原形”开头,To investigate.and;To assess;To determine whether;To study;To examine;,To evaluate and compare;To improve;To describe;To explore;To clarify;To identify。,12,方法(How I did it?)：,论文对研究对象进行研究的过程中所运用的原理、理论、条件、材料、工艺、结构、设备、手段、程

6、序等，是完成研究对象的必要手段。(可写可不写)动词用过去时态。,13,常用英文表达方式,be carried out(performed,made,conducted)developedemployedderivedsynthesizedmonitoreddeterminedmeasured observed,recordedexaminedidentifiedtestedcalculatedproposedevaluatedby means of by the use of in the presence of in the absence of,14,结果(What results did

7、 I get?)：,作者运用研究方法对研究对象进行实验、研究所得到的结果、效果、性能、数据，被确定的关系等，是进行科研所得的成果。描述结果要尽量用具体数据，而不要过于笼统。谓语动词用过去时态。,15,常用英文表达方式,was(were);We found;There was。,16,（不）相符的表示方法,(to be)in good agreement with(to be)consistent with(to be)essentially identical with(to be)contrary to(to be)in contrast with,17,结论(What conclusion

8、s can I draw?)：,作者对结果的分析、研究、比较、评价、应用、提出的问题等，是结果的总结，显示研究结果的可靠性、实用性、创新性，体现论文研究的价值与学术水平，突出论文的主要贡献和创新、独到之处。动词时态用一般现在时或现在完成时。最好直接写结论,也可用一些句型引出结论。,18,常用英文表达方式,is;The authors/Our suggestion(conclusion)is that;This study/article shows(suggests,confirms,reveals,indicates,demonstrates)that;It was shown(found,

9、discovered,concluded,revealed)that It can be seen that These observations support,19,英文摘要的时态,目的说明，用一般现在时、现在完成时或一般过去时。材料、方法和结果部分,除指示性说明外，一律用一般过去时。过去完成时只用于说明研究前的情况或研究中某一点时间之前发生的情况。,20,结论部分：凡陈述研究的材料、方法和结果时,一律用过去时;分析结果或发现的原因时,或者提出结论性意见时,如果作者认为具有普遍意义,可用现在时;如果作者认为自己的分析或结论只限于本研究范围或者仅是一种可能性,则用一般过去时为好。,21,英文

10、摘要的人称和语态,有相当数量的作者和审稿人认为,科技论文的撰写应使用第三人称、过去时和被动语态。但调查表明,科技论文中被动语态的使用在1920-1970年曾比较流行,但由于主动语态的表达更为准确,且更易阅读,因而目前大多数期刊都提倡使用主动语态。国际知名科技期刊“Nature”,“Cell”等尤其如此,其中第一人称和主动语态的使用十分普遍。为了解专业期刊对写作风格的规定,有人随机抽查了500份医学和生物学英文期刊的“读者须知”。统计表明,82%的期刊没有文风方面的规定。可见,为简洁、清楚地表达研究成果,在论文摘要的撰写中不应刻意回避第一人称和主动语态。,22,注意问题,中文摘要前加“摘要：”或

11、“摘要”作为标志，英文摘要前加“Abstract:”作为标志。尽量用短句。以重要事实开头，不以辅助从句开头，叙述要完整，清楚简明，尽量用短句，并避免句型单一。提倡使用非谓语短语和介词短语进行逻辑关联，提倡使用公知的缩略语，不常用或新的术语首次出现时用全称，以后用简写。描述作者的工作一般用过去时态，但在陈述由这些工作所得出的结论时，应该用现在时态。,23,少用复合句。避免使用一长串形容词或名词来修饰名词，要组织好句序,使动词尽量靠近主语。一般都应使用动词的主动语态，如：写成A exceeds B比写成B is exceeded by A更好。摘要中不要出现公式、图表及特殊的字符。不使用俚词外语表

12、达概念，慎用行话和俗语，应用标准英语。,24,删繁从简,例如：at a temperature of 250 to 300 at 250 to 300 at a high pressure of 2 kPa at 2 kPahas been found to increase increasedfrom the experimental results,it can be concluded that the results show,25,能用名词做定语时就不要用动名词,例如:measuring accuracy measurement accuracy能用动词、形容词的情况尽量避免用动词的

13、名词形式 例如:measurement of thickness of plastic sheet was made thickness of plastic sheets was measured experiment results experimental results,26,可直接用名词或名词短语作定语的情况下，要少用of句型 例如:accuracy of measurement measurement accuracystructure of crystal crystal structure,27,1.通常论文摘要的第一句点题 常用的句型有：(1)The author/write

14、r of the article reviews(presents,gives,points out,discusses,analyses，tries to describe,explores,holds,deals with,summarizes,examines,investigates,researches into),28,(2)This article/paper/essay)approaches(holds,reports,reviews，touches upon,tells of,is about,concerns),29,2.介绍内容的句子 常用的句型有：(1)Examples

15、 of demonstrate that(2)Statistics confirm that,30,注意在英文摘要中，句子的主语通常使用第三人称，动词的时态以一般现在时为主。,论文摘要的写作示例讲解,31,1.松嫩平原盐碱土对水稻叶绿素含量的影响,摘 要:采用盆栽法，研究了不同盐碱胁迫对吉89-45和吉农大10的叶绿素总量、叶绿素a和叶绿素b含量的影响。结果表明，同一盐碱胁迫处理下，生育前期叶绿素含量低，之后逐渐增加，到抽穗期达最大值，然后又开始下降，2个品种叶绿素含量变化趋势基本一致。各处理的叶绿素含量始终低于对照。另外，不同处理中叶绿素a含量的变化范围始终大于叶绿素b含量的变化范围。关键词

19、稻饱和光合速率介于WT 和C4 玉米之间,稍偏向玉米,而水分利用效率与WT 接近。由于玉米C4 基因的导入,PKM 水稻高表达了相关的C4 光合酶。在高光和高温条件下,PKM 水稻光合速率比原种提高55%以上。另外,虽然PKM 水稻光合速率增加,但蒸腾速率亦升高,因此PKM 水稻的水分利用效率略有增加,偏向原种。在光氧化条件下,PKM 水稻耐光氧化能力进一步增强。关键词:转基因水稻;光合特性;水分利用效率,34,2.Physiological Performance of Transgenic Rice Expressing C4 Genes,Abstract:In this study,th
