Points of English Style What is a scientific paper?What is a scientific paper?什么是科技论文？什么是科技论文？oA paper is an organized description of hypotheses,data and conclusions,intended to instruct the reader.Papers are a central part of research.If your research does not generate papers,it might just as well not have been done.“Interesting and unpublished”is equivalent to“non-existent.”o科技论文是集假说、数据科技论文是集假说、数据和结论为一体的概括性描和结论为一体的概括性描述，以此向读者论述。论述，以此向读者论述。论文是研究工作的中心部分。文是研究工作的中心部分。如果你的研究没有写成论如果你的研究没有写成论文，也就等同于没有做研文，也就等同于没有做研究。有意义但没有发表，究。有意义但没有发表，等同于不存在。等同于不存在。oRealize that your objective in research is to formulate and test hypotheses,to draw conclusions from these tests,and to teach these conclusions to others.Your objective is not to“collect data.”o要意识到研究的目的要意识到研究的目的是为了形成并证实假是为了形成并证实假说，从一些测试中得说，从一些测试中得出结论，并把结论传出结论，并把结论传授给别人。你的研究授给别人。你的研究目的不是简单的收集目的不是简单的收集数据。数据。What is a scientific paper?什么是科技论文？什么是科技论文？oA paper is not just an archival device for storing a completed research program,it is also a structure for planning your research in progress.If you clearly understand the purpose and form of a paper,it can be immensely useful to you in organizing and conducting your research.o一篇论文并不仅仅是收集一篇论文并不仅仅是收集已经得到的研究结果，它已经得到的研究结果，它也有助于形成进一步的研也有助于形成进一步的研究工作的框架。如果明确究工作的框架。如果明确了论文的目的，这对于计了论文的目的，这对于计划开展你的研究工作有很划开展你的研究工作有很大益处。大益处。What is a scientific paper?什么是科技论文？什么是科技论文？oA good outline for the paper is also a good plan for the research program.You should write and rewrite these plans/outlines throughout the course of the research.At the beginning,you will have mostly plan;o好的文章提要也是研好的文章提要也是研究工作的好计划，在究工作的好计划，在研究的过程中，应该研究的过程中，应该反复修改这些计划或反复修改这些计划或提要。研究工作开始提要。研究工作开始时，应有完善的计划；时，应有完善的计划；What is a scientific paper?什么是科技论文？什么是科技论文？oat the end,mostly outline.The continuous effort to understand,analyze,summarize,and reformulate hypotheses on paper will be immensely more efficient for you than a process in which you collect data and only start to organize them when their collection is“complete.”o工作结束时，应充分的总工作结束时，应充分的总结。最有效率的做法是及结。最有效率的做法是及时的理解，时的理解，分析，分析，总结，总结，形成假说；形成假说；而不是等到完而不是等到完成时才开始收集和整理数成时才开始收集和整理数据。据。What is a scientific paper?什么是科技论文？什么是科技论文？The reason for outlinesThe reason for outlines.为什么要写提纲？为什么要写提纲？oI emphasize the central place of an outline in writing papers,preparing seminars,and planning research.I especially believe that for you,and for me,it is most efficient to write papers from outlines.o我在这里要强调提纲我在这里要强调提纲在论文写作，准备报在论文写作，准备报告以及研究计划中的告以及研究计划中的重要作用。我尤其相重要作用。我尤其相信按照提纲进行写作信按照提纲进行写作对我们大家都是最有对我们大家都是最有效的方法。效的方法。oAn outline is a written plan of the organization of a paper,including the data on which it rests.You should,in fact,think of an outline as a carefully organized and presented set of data,with attendant objectives,hypotheses and conclusions,rather than an outline of

text;o提纲本身应该文字简练。提纲本身应该文字简练。如果大家都同意提纲中的如果大家都同意提纲中的细节部分，那么正文组织细节部分，那么正文组织起来就更容易。在我们就起来就更容易。在我们就提纲达成一致以前，写正提纲达成一致以前，写正文是没有意义的。文是没有意义的。写文章写文章时，大部份时间花在写正时，大部份时间花在写正文上；文上；The reason for outlines.为什么要写提纲？为什么要写提纲？omost of the thought goes into the organization of the data and into the analysis.It can be relatively efficient to go through several(even many)cycles of an outline before beginning to write text;writing many versions of the full text of a paper is slow.o而大部份思考是用在整理而大部份思考是用在整理和分析数据。在动笔前，和分析数据。在动笔前，详细讨论几遍写作提纲会详细讨论几遍写作提纲会提高写作效率；写很多遍提高写作效率；写很多遍正文反倒很慢。正文反倒很慢。The reason for outlines.为什么要写提纲？为什么要写提纲？oAll the writing that I do-papers,reports,proposals(and,of course,slides for seminars)-I do from outlines.I urge you to learn how to use them as well.o我写的所有文章，包我写的所有文章，包括论文，报告，括论文，报告，建议建议（当然还有讨论会的（当然还有讨论会的胶片）都从提纲开始。胶片）都从提纲开始。我也希望你们能学会我也希望你们能学会使用它。使用它。The reason for outlines.为什么要写提纲？为什么要写提纲？How should you construct an outline?How should you

make?”“What compounds?How were they characterized?”o自问一些显而易见的问题：自问一些显而易见的问题：为什么我要做这项工作？为什么我要做这项工作？它意味着什么它意味着什么?我要验证我要验证哪些假设哪些假设?我究竟验证了我究竟验证了哪些假设？哪些假设？结果如何？结果如何？这项工作产生了新方法或这项工作产生了新方法或新物质吗？都是什么？我新物质吗？都是什么？我都做了那些测试？什么化都做了那些测试？什么化合物？合物？它们是如何表征的它们是如何表征的？How should you construct an outline?你应该如何起草你的提要？你应该如何起草你的提要？oSketch possible equations,figures,and schemes.It is essential to try to get the major ideas written down.If you start the research to test one hypothesis,and decide,when you see what you have,that the data really seem to test some other hypothesis better,dont worry.o展示相关的方程，图表和展示相关的方程，图表和示意图。试着写出主要的示意图。试着写出主要的观点。如果你的研究开始观点。如果你的研究开始是为证实一个假设，然而是为证实一个假设，然而当你发现你有的数据仿佛当你发现你有的数据仿佛真的可以更好地验证其它真的可以更好地验证其它的假设时，你也不必担心。的假设时，你也不必担心。How should you construct an outline?你应该如何起草你的提要？你应该如何起草你的提要？oWrite them both down,and pick the best combinations of hypotheses,objectives and data.Often the objectives of a paper when it is finished are different from those used to justify starting the work.Much of good science is opportunistic and revisionist.o把它们两者都写出来，去把它们两者都写出来，去选择假设，目的和数据的选择假设，目的和数据的最佳组合。时常，当一篇最佳组合。时常，当一篇文章完成时，它的目的和文章完成时，它的目的和开始时是不同的。许多好开始时是不同的。许多好的科学来自机遇和反复修的科学来自机遇和反复修正。正。How should you construct an outline?你应该如何起草你的提要？你应该如何起草你的提要？oWhen you have written down what you can,start with another piece of paper and try to organize the jumble of the first one.Sort all of your ideas into three major
