Some friends may not understand that the journals that publish papers are graded. When the quality of papers becomes an important index to measure our scientific research ability, the score of sci papers is born. So what is the grade of journals that publish papers? How are these levels divided? Let's walk into this article with these questions!

Grading and Classification of Papers Published Journals

First, the classification of papers published periodicals

Publicly published papers are divided into six levels:

Class I-T: Papers published in specialized journals refer to papers published in Science and Nature.

Class II -A: authoritative core publications, which refer to internationally accepted SCIE, EI, ISTP, SSCI and A &；; Papers included in the HCI retrieval system (subject to the retrieval by China Institute of Science and Technology Information) or papers on the same topic published by authoritative Chinese core journals in China do not contain reportable abstracts, abstracts, news, etc.

Grade III-B: Important core journals refer to papers published in foreign core journals (see Handbook of Foreign Science and Technology Core Journals) or papers with important influence published in Chinese core journals of similar disciplines in China.

Grade 4-C: The general core periodical papers refer to the papers published in "Overview of National Chinese Core Periodicals" and "Peking University Library 20 10 Edition".

Grade 5-D: Papers published in general public journals refer to papers published in domestic public journals (journal numbers "CN" and "ISSN" with postal codes).

Category VI-E: Papers published in restricted public publications refer to papers published in domestic public publications (only periodical number, no postal code).

Second, the writing points of the paper to be published

1. Persuasive and valuable abstraction!

(1), provide introductory background information and lead to your goal statement. It is best to let readers know why you are doing this research in 1-3 sentences.

(2) Summarize the basic design of your research project. You don't need too many details, but you should briefly explain the main technologies used.

(3) Clearly describe the most important findings of the study, and provide as detailed details as possible at the end.

(4) Briefly state the conclusion to avoid exaggeration. At the end of the manuscript, write a sentence with theoretical and practical significance related to the project, so that readers can understand the importance of your research more clearly.

(5) Visualize your abstract and present it in the form of video, so that your manuscript will be more advanced and brilliant.

2. Standard and clear manuscript format!

(1), check the journal submission guide and determine the correct citation format of references.

(2) Ensure that the documents cited in this paper are indeed listed in the attached references; If the numbering reference format is used, its sequence should be correct.

(3) It is best to verify references through PubMed or Google Academic to ensure that all references are accurate.

(4) Use a uniform font throughout. The title of each part should be clear, definite and consistent. Use page breaks instead of blank paragraphs to separate different parts of a document.

3. "HD No Code" paper chart!

(1), the picture should be of high resolution.

(2) Ensure that the brightness and contrast of all pictures in the manuscript are consistent.

(3) Don't combine multiple images in one area.

(4) Do not enhance, hide, move, delete or add any specific features in the image.

(5) Brightness, balance or contrast can be adjusted, but only if the adjustment of the whole image is unified. And each pixel should be linearly adjust.
