19、,2.3.3 Introduction,一个好的Introduction相当于文章成功了一半！,(1) 阐述自己研究领域的基本内容要尽量简洁明了,(2) 文献总结回顾 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，特别是最新的进展和过去经典文献的引用；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；此外，引用文献时不要原文抄录，要用自己的话进行总结描述。,2020/10/23,How to Write & Publish a Scientific Paper,54,(3) 分析过去研究的局限性并阐明自己研究的创新点 阐述局限性时，需要客观公正评价别

20、人的工作。在阐述自己的创新点时，要紧紧围绕过去研究的缺陷性来描述，完整而清晰地描述自己的解决思路。中文文章的特点是创新性要多要大，而英文文章的特点恰恰相反，深入系统的解决一到两个问题就算相当不错。,(4) 总结性描述论文的研究内容，可以分为一二三四等几个方面来描述，为Introduction做最后的收尾工作。,2020/10/23,How to Write & Publish a Scientific Paper,55,2.3.4 Methods,描述论文实验过程，重要的在于完整和科学。该部分可按实验对象、实验设备、实验材料、实验记录、实验分析方法等来组织行文。,(1) 实验对象，一般是人、动

21、物或一些组织等，它们的基本信息要描述明确；此外要注意国外刊物大多对牵扯到人或动物的实验都有一些特定要求，有些是不允许在人或动物身上进行的实验操作，这需要认真阅读投稿刊物中关于实验的详细规定；如果违反这一规定，可能会不接受评审或发表。,(2) 实验设备，要对仪器型号、生产厂家、实验过程中的用途等作详细说明；实验设备之间的连接要科学正确，不要给人混乱或操作错误的感觉。设备使用时一些必要的步骤不可或缺，尤其是可能对实验结果造成特定影响的操作更要详细说明。一定要详细说明你的操作步骤或校正过程，便于评审人分析你的结果。,2020/10/23,How to Write & Publish a Scient

22、ific Paper,56,(3) 实验材料，不同学科有不同要求。总体上来说要注意说明材料选择的必要性，也就是对为什么要选择这种材料，最好有一定的说明。,(4) 实验过程，就是清楚描述实验的整个操作流程，一般要附以实验流程图进行说明。描述时要有鲜明的层次感，对每个步骤之间的顺序和关联要描述清楚，不要造成实验过程混乱不堪的印象，因为评审人最终判断你的实验是否合理，是从这个过程描述得来的。,2020/10/23,How to Write & Publish a Scientific Paper,57,2.3.5 Results,(1) Results的要求是翔实准确。从某种意义上来说，结果不够翔实

23、并不导致论文直接被拒，但结果的真实性被怀疑文章就肯定被拒。,(2) 结果提供一般包括表和图。表格能清晰展示论文获得的第一手结果，图示能将数据的变化趋势灵活的表现出来，更直接和富于感染力。杂志会尽量限制图的个数，因为会增加排版的困难，版面费和出版社的支出也就会增加。图片格式要求每个杂志不同，用tif格式较多，不推荐用bmp(jpg更不能用)。黑白图片可免费，彩色图片要收费。,(3) Results和Discussion分开写时，Results部分尽量不要涉及对结果的评论，最多是总结陈述结果就可以了。结果的描述也要注意层次安排，要按照条理性要求分别描述，显得逻辑性较强。,(4) Results中大

24、多要提供统计结果。如果论文结果部分通篇都是统计分析的数据，会显得凌乱不堪，表格可以避免这种情况。,2020/10/23,How to Write & Publish a Scientific Paper,58,2.3.6 Discussion,(1) 选择要深入讨论的问题。如果你的结果体现了实验的独特性，是其他研究中没有得到的，那这个结果就是要重点讨论的问题。Discussion的一个重要作用就是要突出自己研究的创新性，并体现出显著区别于他人的特点。,(2) 对选中的问题按一定层次从多个角度进行讨论。 a) 首先要有类似结果的对比，说明自己结论的独特性；b) 其次要系统阐述为什么会有这样的结果

25、。,(3) Discussion部分必须和Results保持一致。Discussion的文字描述和语言表达的精确性尤为重要。,2020/10/23,How to Write & Publish a Scientific Paper,59,2.3.7 Acknowledge & References,Acknowledge：1) 表明研究的基金来源，要标注清楚基金号码(Grant Number)；2) 对参与人员(没有列在作者中的研究人员)和单位表示感谢，如果通过一审和最终接受发表，还要添上对editor和anonymous reviewers的感谢。,References：重要在于格式。不同杂

26、志对参考文献格式要求不一样。,2020/10/23,How to Write & Publish a Scientific Paper,60,2.4 英语学术论文写作的几个细节,(1) 时态：当提到本文、此图、此表等说明了、表达了什么时要用一般现在时，而不用一般过去时。 This paper describes The focus of this paper is Figure 1 shows Most of the common condensation polymers are listed in Table 1-1.,(2) 数：在学术论文里，有时很难顾及数的逻辑。但一般不将逻辑上的问题

27、视为语法错误。只须注意在一个句子中的数和谓语动词的统一即可。单、复数的选用有一些非定性、但可供参考的趋向：,2020/10/23,How to Write & Publish a Scientific Paper,61, 当含意上强调复数时建议用复数 The catalyst concentrations for the different reactions are different.
