The signature of the paper is a very important and serious matter. Basically, the writing and publication of a paper are done by several people in many cases, so the signature must also be signed by several authors. There are not too many requirements and restrictions on the number of authors' signatures in academic circles. As long as the signatures match the situation of the article, the number is reasonable.

Requirements for document signature:

1, the signature should be consistent with the actual situation of the article. If there are too many signatures and they don't conform to the actual situation of the article, the article will be greatly discounted. Therefore, the number of signatures must conform to the actual situation of the article.

2. The number of authors of papers published at different levels is different. If the paper is published in a general journal, many authors can do it independently. If the paper is published in a core journal, it is difficult to complete it independently, and cooperation with other authors is needed. If it is an international academic article, it may need a team to do it, and it is understandable that the paper has many signatures.
