1.科学研究不能仅因为已发表,就认为它是完美的。
它们的不足也不是微小到只有专业人员才能发现。
任何从事科研的学生都能,而且确实应该能够,批判性地阅读科学文献。
这意味着你读一篇诺贝尔奖获得者的文章都能在其中发现不足。
它实际上期望作为科学工作者的你能对任何学科进行分析评论。
你分析评论的水平会因你的经验水平而有差异,但你应该至少能够像一名相对无经验的本科生来分析科学文献。
Just because a scientific study has been published, this does not mean it is perfect. And the imperfections are not so minute that a non-expert cannot find them. Any student of science can, and indeed should, read science critically. This means you can read a paper by a Nobel laureate and find fault with it. It is in fact expected that, as a practicing scientist, you can criticize any science. The level of your critical analysis will differ with your experience level, but you should be able to criticize science even as a relatively inexperienced undergraduate.2.简单地说,他们是否回答了他们的问题?他们是否作了正确的实验来说明他们的问题?如果你列出的实验目录与他们的不同,他们的实验体系是否更好?有时并不是!如果你不得不回答这些问题,了解所有目前你所知道的,你会怎样作?可能会借鉴他们的实验?或与他们做的一模一样?精彩的研究论文的实验恰到好处,这样的文章是不多的。
Simply put, did they answer their question? Did they do the right experiments to address their question? If your list of experiments differs from theirs, is their line of experimentation better? Sometimes it isn’t! If you had to answer this research question, knowing all that you know now, how would you do it? Maybe borrow some of their experiments? Or do exactly what they did? Great papers are those that do it exactly right, and they are rare.3.早期的人类仅仅使用了非常有限数量的材料,比如自然的石头、木头、粘土、兽皮等等。
随着时间的发展,通过使用技术来生产获得的材料比自然的材料具有更加优秀的性能。
这些性材料包括了陶瓷以及各种各样的金属,而且他们还发现通过添加其他物质和改变加热温度可以改变材料的性能。
此时,材料的应用完全就是一个选择的过程,且此过程又是根据材料的性质从许多的而不是有限的材料中选择一种最适于某种用途的材料.The earliest humans had access to only a very limited number of materials, those that occur naturally: stone, wood, clay, skins, and so on. With time they discovered techniques for producing materials that had properties superior to those of the natural ones; these new materials included pottery and various metals.Furthermore, it was discovered that the properties of a material could be altered by heat treatments and by the addition of other substances. At this point, materials utilization was totally a selection process that involved deciding from a given, rather limited set of materials the one best suited for an application by virtue of its characteristics.4.有时这个工艺使得占主导地位的材料和辅助的材料必须是兼容的。
这是一个配合。
兼容性不容易找到,很多失败的匹配和材料的失效都可能是灾难性的,伴随着责任和赔偿问题。
这听起来像食品律师,有时候是:一些专家,在法庭材料失败的案件中作为专家证人。
但我们在此的目的不是争辩,而是让大家对材料世界(因为即使是在遥远的外星球你也能发现相同的元素)和加工领域有一个了解,而且提供选择材料的方法和工具,以确保材料性能能长期友好地结合起来。
Sometimes it is the process that is the dominant partner and a material-mate must be found that is compatible with it. It is a marriage. Compatibility is not easily found—many marriages fail and material failure can be catastrophic, with issues of liability and compensation. This sounds like food for lawyers, and sometimes it is: some specialists make their living as expert witnesses in court cases involving failed materials. But our aim here is not contention; rather, it is to give you a vision of the materials universe (since, even on the remotest planets you will find the same elements) and of the universe of processes, and to provide methods and tools for choosing them to ensure a happy, durable union.1.Read the text of the results without critiquing the data. Go slowly and carefullyhere. Since this is your first pass through the data, do not try to take it all in at once. Again, look for specific information and ignore the rest. This time, you are looking for a good understanding of what the experiments were: what did they do? The goal here is to get into the minds of the authors: Let them tell you why they did the experiments, and what they think happened as a result. Assume everything they tell you is the absolute truth. This is where you compare your list with theirs. Write down what differences there are, and note why you think the lists are different: are the authors leaving things out you’d like to see, or are they on a different track than you? The key here is to fully understand their train of thought. If you can’t figure it out, write that down, too, specifying exactly where you fell off the train. Then move on. From here on, focus on the material you understand from the Results, and ignore what you don’t understand. BE CRITICAL: Assume they are trying to pull a fast one on you. Make sure that when they say something, the data actually show it.阅读正文的结果部分,不评价数据。
这里要慢点,仔细点。
既然这是你第一次浏览数据,不要试图一次就全盘拿下。
应再次寻找特殊的信息并忽略其它的。
这次你要寻找的是透彻地理解该实验是什么:他们作了什么?这里的目的是进入作者的思想里:让他们告诉你他们为什么作这些实验,他们认为的结果是什么。
