If there is a tie for the first author, when the paper is published, the words "tie for the first author", "equal contribution" and "same contribution" will be marked. In more detail, they will explain the chapters they are responsible for.

The first author can still play a big role in the paper, and his contribution to the paper is also relatively large, followed by the second author and the third author. In the evaluation of professional titles, the higher authors rank is, the more points he gets. Is the second author of a specific paper useful? Can the third author be recognized when evaluating professional titles? How many points can I add? The provisions of the unit shall prevail.

Although a paper can have one or more first authors, not all journals are allowed to have multiple first authors, and not all units will treat the same work with the same title. If there is an express stipulation that it is not recognized, then don't tie the first author. If the title is recognized as * * * 1, then the author needs to mark it clearly as required. It is suggested that before preparing the evaluation materials, we should first understand the requirements of the unit and the requirements of contributing journals.

On the signature of innovative works, such as scientific research papers, patents, research reports, etc. The name of the person who has made the greatest contribution to the work is usually signed at the front. Especially for the signature of scientific research papers, each journal has more detailed regulations; However, when the paper signature is used to evaluate professional titles, the weight of the first author is obviously heavier than that of the second and third authors, but lighter than the personal signature.

Due to the complexity and diversity of scientific research, such as the case that a paper in bioinformatics has hundreds of signatures, the first author refers to the first few people, not just the first one; The situation of multiple first authors will be clearly marked. In addition, the first author is different from the correspondent and creative contribution, and the correspondent is often the most authoritative person in the field of papers.
