Long paper: A long paper with at most six authors, no matter how many, is inappropriate.

In short, no matter what level of periodicals we publish, it is best not to have more than four authors! ! ! If the paper is less than 4000 words, it is best not to exceed three authors! ! ! To tell the truth, the short essays of four authors are a joke.

If it is more than 6000 words, you can sign four authors according to the situation, but there are no special circumstances, it is best to sign three authors. Many published papers are used to evaluate professional titles, so remind your family that if your article clearly requires that the paper must be published by the first author or independent author, then you can only publish the paper according to this requirement. If you sign the second author or the third author or you are not an independent author, the professional title evaluation will be invalid.

If an academic task is completed in order to evaluate professional titles, it is generally explicitly required to publish multiple papers as the first author or independent author and multiple papers as the second author. However, there is basically no literature that requires several papers to be the third and fourth authors, and this requirement is rare. Therefore, there are more than three authors, and the latter one is of little practical significance except that it is a bit famous for publishing papers.

Non-core journals: provincial journals, national journals, published papers, signed by the fourth author, or the fifth author, are of little significance.

Core journals: North Nuclear, South Nuclear and SCI. The articles are long, and it is understandable that the articles are signed by four authors, but no more than four. At this time, even if you are the fourth author, it is better to say that it is a core journal, because it is a core journal after all.
