Generally, it is about 1-3 articles. Sci thesis is a general requirement for doctoral graduation. How many papers to publish, when to publish, whether to publish or be searched, etc. , will vary from school to school.

There are many schools where doctors study, and each school has corresponding regulations for doctoral papers. As for the number of published sci papers, some are more than others, and even different disciplines in the same school have different requirements for the number of articles. For example:

1, BUAA Mathematics (Statistics)

(1) Basic requirements (meet one of the following two conditions):

(1) published 2 papers in source journals included in SCIE;

②SCIE published 1 paper, and 2 papers were published in EI and MEDLINE or China Science (Chinese version), Journal of Mathematics, Journal of Applied Mathematics, Computational Mathematics or System Science and Mathematics.

(2) requirements for avoiding blind test:

Published papers 1 article in SCIE source journals (Q 1 region or Q2 region in the partition table).

2. Materials Science and Engineering, Chemistry, Beihang University

(1) Basic requirements:

There are 3 papers published in SCIE source journals, and the cumulative impact factor is above 3.0 (inclusive). The papers published in foreign journals with impact factors above 1.0 (inclusive) are at least 1 paper.

(2) requirements for avoiding blind test:

The impact factor of papers published in SCIE source journals is 8.0 or above, and the impact factor of at least 1 paper published in foreign journals is 3.0 or above.

3, Northwestern Polytechnical University doctor of science degree, must meet one of the following conditions:

(1) published 4 academic papers in SCI, EI retrieval source journals and the Guide to Submission of Academic Papers of Northwestern Polytechnical University. At least 2 journal papers were retrieved by SCI (at least 1 mathematical papers were retrieved by SCI), and at least 1 foreign language papers were retrieved.

(2) publishing at least 1 high-level academic papers in international academic journals retrieved by SCI, which belongs to SCI? Region 1 (Mathematics belongs to SCI? 1 or 2), or the cumulative impact factor of SCI reaches above 5.0 (Math 4.0).

How can I have the ability to publish SCI papers? Here we share three basic skills: solid professionalism, solid English and solid scientific research tools.

(1) Professional and solid

Textbooks are usually about widely accepted and outdated knowledge. This knowledge must be understood, and you can be very skilled in some data, formulas or professional common sense.

(2) Solid English.

Now the English of the younger generation is better than our English at that time. Therefore, I don't want to say more here. When reading literature, pay more attention to the author's words, the expansion of sentences and the expansion of paragraphs.

(3) Solid scientific research tools

Including indoor and outdoor (if necessary) experimental skills and the main software tools needed in the process of article writing. Different majors have different requirements about experiments. What I want to talk about here is the software tools you may use in the process from raw data to manuscript: text (for example? Words? ), graphics (such as? Origin? SigmaPlot… ...), data analysis and statistics (for example? Excel，？ SPSS？ Or? SAS…), data simulation? (for example? MathCad，？ Matlab…), literature management (for example? Endnote …) and its professional software. Mastering the above software skillfully can not only write articles quickly, but also have a certain depth.
