I Have a Research Support System

Last semester, Xu Qiu took the elective course of "Literature Retrieval".

The 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 lecturer 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, which will be included in their usual grades.

In order to complete the homework, Xu Qiu downloaded many documents, but he did not read the content of the documents carefully, which also caused his current document reading ability to be a poor 50% of the first level.

It is still necessary to learn more skills in case of emergencies, Xu Qiu thought.

However, he still knows some basic common sense.

In the upper left corner of the document, he found the name of the journal—"Chemical Review", and then checked it on the MedSci website.

The impact factor is 52.758, and the TOP of the first area of ​​the Chinese Academy of Sciences' division of chemistry.

Then, he looked at two other documents, namely "Advanced Materials" and "Energy and Environmental Science".

Both of them are TOP in the first division 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, "Cell", "Nature" and "Science" on the website.

There is no doubt that they are all TOP in the first district, with impact factors of 38.637, 42.778 and 41.845 respectively.

Although the impact factors of "Chemical Reviews", "Advanced Materials" and "Energy and Environmental Science" are not much different from those of CNS, their influence is not at the same level.

From the perspective of journal grades, CNS is half to one and a half grades higher.

Seeing that the proficiency only increased by 1%, Xu Qiu didn't care too much.

This shows that compared with the operation of "ultrasonic cleaner", "tweezers" and other equipment, it is more difficult to improve the ability of literature reading, and it 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 the blessing of the system.

He activated the auxiliary system to continue studying.

The second step is to confirm the article type.

The common types are Review, Article and Communication, in addition to Letter and Comment and so on.

Review is a review type of article, which generally summarizes the recent research progress in a certain research field, and the article is usually cited more frequently.

Some journals only collect review articles, and this type of journal has a high impact factor. For example, "Chemical Review" has an impact factor as high as 52.758.

Article and Communication are articles of the experimental report type, usually researching specific scientific issues.

If a research field is likened to a building, then each Article or Communication article is a brick that makes up the building.

Of course, there are also differences between the two types.

The former focuses on expressing "I have done a complete and systematic work". Usually, the experimental data is rich, the system is complete, and the length is relatively long;

The latter focuses on expressing "I put forward a new point of view, or got a new conclusion", and has higher requirements for the novelty of the article, and the length of the article is shorter.

Xu Qiu looked at the types of documents in his hand, and sure enough, all three were of the Review type.

The third step is to read the title of the document and determine the subject of the document.

The title of the article is usually short, and it is not difficult to read. Except for the technical term "body heterojunction" translated by Gugou, Xu Qiu can understand the rest.

"Recent Developments in Bulk Heterojunction Polymer Solar Cells"

"Bulk Heterojunction Organic Solar Cells: Five Key Technologies for Commercialization"

"Recent Developments in Organic Photovoltaics: Device Structure and Optical Design"

The fourth step is to read the abstract and conclusion.

The abstract and conclusion is the most essential part of an Article or Communication, which summarizes the core arguments and arguments of the entire article in hundreds of words.

Often, the abstract and conclusion are largely repetitive, using two sets of words to describe the same story.

The subtle difference is that the abstract will mention why such work is done, which is equivalent to the prequel of the story;

The conclusion will involve the prospect of future work, which is somewhat similar to the postscript of the story.

Unfortunately, for the three reviews in Xu Qiu's hands, none of the above is true.

Because a specific job can be summarized with a few words, but for a large field, if you want to summarize it in just a few hundred words, you will definitely lose a lot of information.

Just like describing a brick, it can be described by length, width, height, color and material. It is easy for others to imagine what the brick looks like by providing very 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 have a building in your heart, then it is 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 found that he knew almost every word he knew, even if he didn't know it, he had annotated it through Gugou and Youpirate, but his eyes were still darkened, and he didn't know what to say.

This feeling is like encountering such a topic:

Known: Every atom that makes up a brick is on the periodic table.

Solution: What does it look like to build a building with bricks.

After gnawing at the documents for an hour, Xu Qiu felt a little pain in his head, so he called up the system interface and checked the results.

【Scientific Research Auxiliary System】

...

【Special class】

Literature reading (first stage 57%/third stage 0%)

I feel that I have learned a lot of knowledge, but my proficiency has only increased by 7%.

He still misses the fact that the proficiency level of the ultrasonic cleaner rose to four levels in seconds. Although he also knew that it was useless, at least it looked cool.

Xu Qiu murmured to himself for a while, then decided to go to the public bathroom to take a bath, to rest early and fight again tomorrow.

Bathroom opening hours are from 4:30 pm to 9:30 pm.

Although there are bathrooms on each floor of the dormitory, they only provide cold water.

Generally, only when it is too late to go to the public bathroom, students will take a shower with cold water.

While Xu Qiu was preparing the toiletries, Tao Yan came back from the shower.

As soon as he entered, he changed his clothes and straightened his collar, as if he was in a hurry to go out again.

Seeing this, Ren Bin joked, "Tao Yan, are you going out to hook up with the little sister again tonight?"

"Binzi, how do you talk, what is hooking up, we are true love." Tao Yan said.

"Heh, you say true love every time. Have you said true love more than a dozen times? Tell me, where is it from this time?" Ren Bin said.

"A freshman girl from the Chinese Department of our school." Tao Yan said.

Xu Qiu watched the two roommates chattering, shook his head, and did not choose to participate in it.

He packed up his bath tools and changed his clothes, greeted his roommates, and went out.

In fact, Xu Qiu admired Tao Yan a lot.

As far as he knows, Tao Yan's current status is that he has taken compulsory courses but not elective courses, usually does not study, has a three-day rush before the exam, often sees no one at night, and does not know where to go.

In this way, the grade point can still be maintained at 3.0.
