Chapter 7: Literature interpretation

　　 Last semester, Xu Qiu took the professional elective course "Document Retrieval".
　　 course is mainly to teach students to use various retrieval tools to find the required documents, and then download them through the campus network.
　　 The instructor will give a precise research direction, such as "Preparation of PVP nanofibers by electrospinning", and then assign them as homework for students to search and download relevant literature, and count it into their usual grades.
　　 In order to complete the homework, Xu Qiu has downloaded many documents, but he has not read the contents of the documents carefully, which also leads to his current document reading ability is still a poor 50%.
　　 It is still necessary to learn more skills to prepare for emergencies, Xu Qiu thought.
　　 However, he still knows some basic common sense.
　　 In the upper left corner of the literature, he found the journal name-"Chemical Review", and then searched on the MedSci website.
　　 impact factor 52.758, TOP of the Division I Division of Chemistry of the Chinese Academy of Sciences.
　　 Then, he flipped through two other documents, namely "Advanced Materials" and "Energy and Environmental Science."
　　 Both are TOP in the first district of the Chinese Academy of Sciences, with impact factors of 27.398 and 30.289, respectively.
　　 Out of curiosity, Xu Qiu checked the three top journals CNS on the website, "Cell", "Nature" and "Science".
　　 is undoubtedly a district TOP, with impact factors of 38.637, 42.778 and 41.845.
　　 Although the impact factors of "Chemical Review", "Advanced Materials" and "Energy and Environmental Science" and CNS are not very different, the influence is not at the same level.
　　 From the perspective of journal grade, CNS is half to one and a half higher grades.
　　【Literature reading proficiency+1%】
　　 Seeing that his proficiency was only increased by 1%, Xu Qiu didn't care too much.
　　 This shows that compared to the operation of "ultrasonic cleaners", "tweezers" and other equipment, the ability to read literature is more difficult to improve and requires a lot of reading to accumulate.
　　 But this difficulty is the same for almost all scientific researchers.
　　 Of course, except for people like Xu Qiu who have system blessings.
　　 He activated the auxiliary system to continue learning.
　　 The second step is to confirm the article type.
　　 Common types include Review, Article and, in addition to Letter and Comment, etc.
　　Review is a review type article, which generally summarizes the recent research progress in a certain research field, and the article is usually cited more frequently.
　　Some journals only include review articles, and therefore these journals have a high impact factor. For example, "Chemical Review" has an impact factor of 52.758.
　　Articles and articles are experimental report-type articles, usually to study specific scientific issues.
　　 If a research field is compared to a building, then each article or article is a piece of brick that makes up the building.
　　 Of course, there is a difference between the two types.
　　 The former focuses on expressing "I have done a complete and systematic work", usually with abundant experimental data, complete system, and longer length;
　　The latter focuses on expressing "I have put forward a new point of view, or got a new conclusion", which requires more novelty and shorter length of the article.
　　 Xu Qiu looked through the types of documents in his hand. As expected, all three of them were of Review type.
　　【Literature reading proficiency +4%】
　　 The third step is to read the title of the document and determine the topic of the document.
　　 The title of the article is usually short and it is not difficult to read. Xu Qiu can understand it except for the professional term "body heterogeneous junction" translated by Gu Gou.
　　 "Recent Development of Bulk Heterojunction Polymer Solar Cells"
　　 "Bulk heterojunction organic solar cells: Five key technologies for commercialization"
　　 "Recent Development of Organic Photovoltaics: Device Structure and Optical Design"
　　【Literature reading proficiency+1%】
　　 The fourth step, look at the summary and conclusion.
　　 The abstract and conclusion are the most essential part of an article, summarizing the core arguments and arguments of the whole article in hundreds of words.
　　 Usually, most of the content of the summary and conclusion is repeated, that is, two sets of words are used to describe the same story.
　　 The subtle difference is that the summary will mention why such a work is required, which is equivalent to a prequel to the story;
　　 The conclusion will involve prospects for future work, which is somewhat similar to a post-story.
　　 It's a pity that for the three reviews that Xu Qiu held in his hands, all the above are not true.
　　 Because a specific job can be summarized in a few words, but for a large field, if you want to summarize and summarize it in just a few hundred words, you will definitely lose a lot of information.
　　 is like describing a brick. It can be described by length, width, height, color and material. It is easy for others to imagine what this brick looks like with only a little information.
　　 But if you use the same little information to describe a building, it will be hard for ordinary people to imagine.
　　 Unless you are an expert in this field, and you have a building in your heart, that's another matter.
　　 For Xu Qiu now, the foundation of the building has not been dug yet.
　　 Therefore, after spending half an hour barely reading the abstracts and conclusions of the three documents.
　　 Xu Qiu discovered that he knew almost every word. Even if he didn't know, he commented on Gu Gou and You Pi, but his eyes were still blacked out, and he felt incomprehensible.
　　 This feeling is like encountering such a problem:
　　 Known: Every atom that makes up a brick is on the periodic table.
　　 Solve: What is it like to build a building with bricks?
　　【Literature reading proficiency+1%】
　　 After reading the literature for an hour, Xu Qiu felt a little pain in his brain, so he called the system interface to check the results.
　　【Scientific Research Support System】
　　……
　　【Special category】
　　 Literature reading (first order 57%/third order 0%)
　　 I feel that I have learned a lot of knowledge, but the proficiency of UU reading www.uukanshu.com only increased by 7%.
　　 I still miss the previous ultrasonic cleaner's proficiency rising to the fourth step in a second. Although he also knows that it is actually useless, but at least it looks cool.
　　 Xu Qiu muttered to himself for a while, decided to take a bath in the public bath, and prepared to rest early and fight again tomorrow.
　　The bathroom is open from 4:30pm to 9:30pm.
　　 Although there are bathrooms on each floor of the dormitory, only cold water is provided inside.
　　 Generally only when there is no time to go to the public bathroom, students will use cold water to shower.
　　 While Xu Qiu was preparing toiletries, Tao Yan came back from the shower.
　　As soon as he walked in, he changed his clothes and adjusted his collar, as if he was anxious to go out again.
　　 Ren Bin saw this and joked: "Tao Yan, are you going out to hook up with my little sister again tonight?"
　　 "Binzi, how do you talk, what is hookup, we are true love." Tao Yan said.
　　 "Oh, I always say true love every time. You have a dozen times of true love, right? Let's say, where is this time?" Ren Bin said.
　　 "I am a freshman from the Chinese Department of this school," Tao Yan said.
　　 Xu Qiu watched the two roommates chatter, shook his head, and did not choose to participate.
　　 He packed up his bathing tools and a change of clothes, then greeted his roommates and left.
　　 In fact, Xu Qiu still admires Tao Yan.
　　 As far as he knows, Tao Yan's current state is that he has selected compulsory courses, not elective courses, usually does not study, rushes for three days before the exam, often sees no one at night, and does not know where he is going.
　　 In this way, the grade point can still be maintained at 3.0.
