英文科技学术论文Introduction写法
SCI论文引言部分Introduction的写作

SCI论文引言部分Introduction的写作第一篇:SCI论文引言部分Introduction的写作SCI论文引言部分Introduction的写作引言Introduction 是SCI论文最难写的部分之一,很多文章的缺陷就在于Introduction没有内涵,过于简单,没有真正体现论文的研究起初和创新要素,然而,一篇好的SCI论文对于Introduction的要求是非常高的,一个好的引言相当于文章成功了一半。
所以大家应该在 Introduction的撰写上下功夫。
要写好 Introduction,最重要的是要保持鲜明的层次感和极强的逻辑性,这两点是紧密结的,即在符合逻辑性的基础上建立层层递进的关系。
SCI论文引言部分Introduction 主要包括如下四个方面的内容:1、阐述自己研究领域的基本内容。
要尽量简洁明了,不罗嗦;须知看文章者都是该领域的专家,所以一些显而易见的知识要用概括性的而不是叙述性的语言来描述。
2、文献总结回顾。
是引言的重头戏之一,要特别着重笔墨来描写。
一方面要把该领域内过去和现在的状况全面概括总结出来,不能有丝毫的遗漏,特别是最新的进展和过去经典文献的引用(这是两个最容易出问题的地方,要极力避免;一旦审稿人指出这两个毛病,很可能意味着表明你做的不够深入或全面,负面作用非常明显)。
另一方面,文献引用和数据提供一定要准确,切记避免片面摘录部分结果而不反映文献的总体结果;引用的数据也要正确,特别是间接引用的数据(即不是从原文献中查到,而是从别人文献中发现的另一篇文献的数据);数据出错会导致文章的印象特差!此外,引用文献时注意防止造成抄袭的印象,即不要原文抄录,要用自己的话进行总结描述。
如果审稿人正好是文献的引用者的话,原文照抄的结果一定会很糟糕。
3、分析过去研究的局限性并阐明自己研究的创新点。
这是整个引言的高潮,因而要慎之又慎。
阐述局限性时,需要客观公正评价别人的工作,不要把抬高自己研究的价值建立在贬低别人的工作之上(这也是文章易犯的毛病),研究者一定要遵循实事求是的原则来分析。
科学引文索引(SCI)论文的引言(Introduction)怎么写

科学引文索引(SCI)论文的引言(Introduction)怎么写大部分回答都说错了,或者他们根本没有写过够多的文章,正确的introduction,必须为文章的result和discussion部分服务,不能为了综述而综述。
正确的文章的写作顺序应该是,先写experiment和result,这些是你拥有的fact。
比如合成了什么材料,做了什么表征,已经这个材料的性能测试等等。
这是文章核心的价值和必须要清晰的传达的science。
然后基于这些fact去写discussion,主要是结合文献讨论这些fact,讲出文章的亮点。
如果合成本身是亮点,那discussion部分去讲述表征结果证明了材料是其中一种结构,文献用类似合成方法得到过类似结构,但是我们改良的方法可控性更好,或者类似结构之前都用其他方法合成,而我们用了成本更低的新方法等等。
如果性能是亮点,那discussion就去写,我们合成的材料比传统材料在方面性能提升了XX倍,然后结合文献或者用其他实验讨论一下造成性能提升的原因。
这时候才到写introduction的时候,introduction必须要对照着discussion的逻辑去写。
比如discussion说合成材料的方法是亮点,那introduction写该材料被用于ABCD等等领域,很屌,现在主流合成方法,但该方法存在1234条不足,我们的新合成方法可以用于解决这些不足,然后概述一下文章内容就ok了。
同理,如果性能是亮点,那introduction应该是,反应或者应用很屌,很多公司甚至很多国家都很重视该应用,现有用于该应用的材料为,性能为如何如何,同时有1234条不足,我们对该材料进行改良,性能提升了XX倍,同时解决了现有材料的不足。
如果不这么写,只是把introduction当做泛泛的短review,文章很容易逻辑很别扭,经常会出现introduction说方法存在问题,然后文章内容是应用该方法去做研究,而不去解决问题。

科技英语写作(5)—Introduction

引言 有人说引言是最难写的。几乎所有的科技论文都 有引言部分,只是有的论文有专门的一节,有的 论文(比如通讯,快报等)仅仅是论文的第一段。 引言包含四个元素,或者说四个组成部分。 1,研究领域。 ,研究领域。 是与本研究工作的有关的背景介绍。正确地估计 研究课题的意义。应用背景。 也就是为什么要做这项工作。例如在基础研究方 面有何新意,有何应用前景。课题的意义估计不 足,说明作者的知识水平不高,估计过分则显得 不够严谨。

英文科技学术论文Introduction

大多数英文科技学术论文都可以使用一种所谓 Introduction-Methods-Results and Discussion (IMRAD) 的形式,如下图的沙漏所示,先由普遍到具体问题,再由具体到普遍结论。
这里先总结Introduction的写法和注意事项与中文论文“简短”的“概述”(或“前言”)不一样,英文的Introduction内容通常较长。
好的论文在Introduction部分很见功底,文献的阅读量、信息综合能力,可以给读者很多的信息量,因此写好它容不得半点马虎。
Introduction(说明综述)部分的内容通常用来为作者创造一个研究空间。
先介绍目前的研究现状,然后指出存在的不足或尚没有解决的问题,最后再介绍“存在的问题”是“如何”被作者的研究所解决。
因此,Introduction可以由这“三波”或者说“三部分”来组成。
第一波:提出研究现状和此研究的重要性先通过陈述表明所要研究问题的重要性——当然这部分内容不是必须,并介绍此领域的研究现状,具体可参考文献综述引用。
研究问题要与自己的研究内容高度相关,时态一般可用一般现在时,并通过很确定的语气和具体的形容词来强调研究的重要生。
The flow of foams is seen in many process, and its use in major industries means that an understan ding of foam rheology is of paramount importance.第二波:强调有必要解决存在的问题指出该研究目前存在的问题,可以通过提问的方式或者通过某种方式扩展此领域已有知识和结论。
这一波非常重要,只有指出存在的问题或尚待解决的问题,才能突显出自己的研究价值。
在这一部分的写作时,一般通过转折词来表示过渡,并在指出问题时使用负面的词汇。
… however, the relationship between emergence and soil temperature has not been investigated p reviously…In contrast to the extensive literature describing ….., little attention has been paid to…第三波:介绍作者自己的研究内容介绍作者的研究目的和大致的研究内容。
SCI科技论文Introduction四步法写作技巧

SCI科技论文Introduction四步法写作技巧SCI论文的Introduction应该回答"为什么"的问题:你为什么选择该主题进行研究;为什么它很重要;为什么你采用了特定的方法或途径;等等。
你也可以将Introduction看作是指出本领域内的gap的部分(你的result和discussion需要填补这个gap); Introduction也可以用来在广泛的研究领域中定义和主张自己的领域(立“山头”)。
Introduction的另一项工作是提供一些背景信息并设定背景。
您可以通过描述您考虑的研究问题或提出的研究问题(在论文的主体部分,您将提供问题的解决方案或问题的答案),并简要回顾过去尝试过的任何其他解决方案或方法来完成这项工作。
学位论文通常有一个单独的、标题为"文献综述"的章节,但研究论文没有这样的部分;但是,Introduction中包含了简要的综述。
既然你已经给出并设定了背景,那么Introduction的最后一部分既应该明确论文中描述的实验方法或分析研究的目标,也应该包括具体的细节或论文后面要回答的具体问题。
Introduction一般包含三个段落,约占一般研究论文正文总字数的10%,采用“倒金字塔式”写法。
四步法写Introduction1. 提供背景资料,设置背景Introduction的这一初始部分为读者准备了后面更详细、更具体的信息。
前几句一般都是概括性的。
以下是一些例子:一篇关于土壤中有机物的论文可以这样开头:"可持续的作物生产是土壤的物理、化学和生物特性的函数,而这些特性又明显地受到土壤中有机物的影响。
”一篇讨论细菌在治疗癌症方面可能发挥的有益作用的论文,可以这样开头。
"细菌作为抗癌剂的作用早在一百年前就被认识到了。
”一篇关于锂电池的论文可以用以下句子来介绍研究内容:“锂离子电池的快速增长及其新的用途,如为电动汽车提供动力和为电网供应储存电能,这就要求有更可靠的方法来了解和预测电池的性能和寿命。

介绍作者的研究目的和大致的研究内容。
也可以在此部分表明自己的研究假设前提,宣布自己的主要研究发现、它们的价值,如有需要,也可以介绍论文的框架结构——方便读者了解复杂的文章结构。
这部分的内容主要用来介绍作者如何“填补”提出的“问题”或“不足”。
This paper presents the results of an extensive experimental program…
关于此处的时态,比如是presents还是presented? 即是一般过去时还是一般现在时?一般而言:
•如果主语是paper, article, thesis, report等指代文章本身的抽象词汇,使用一般现在时;
•如果主语是实验调查本身,比如study, experiment, investigation等具体词汇,使用一般过去时或一般现在时都可以。
万能法则:此处的时态如果拿不准,一直使用一般现在时。
