The author's signature as the first author, author ranking and corresponding author represents copyright and can declare one's own academic achievements.

Author ranking is one of the most critical evaluation indicators in terms of professional title promotion, scientific research fund application, job search, and talent title evaluation.

Many universities value the works of the first author and corresponding author when evaluating qualifications.

Since author signatures are closely related to academic reputation and economic interests, scientific researchers pay special attention to author rankings.

According to the order of arrangement, the authors are divided into first, second, third author, etc.

According to classification, authors are divided into ordinary authors and corresponding authors.

The corresponding author is also called a corresponding author because this type of author is responsible for responding to letters.

Arrange the authors of the paper. Note that the order of author arrangement is divided into three types: alphabetical ordering by surname, first and last author ranking, and contribution ranking.

The alphabetical ordering method of last name is used when it is impossible to distinguish the degree of contribution of each author, and the alphabetical order of last name should be noted at the signature.

Although this method is indeed used, it is not advocated by the academic community.

The first-last author ranking method means that the student or team member is the first author, the supervisor or project leader is the last author, and the other contributors are arranged in the middle.

Although this method once formed a common political consciousness in some countries or certain fields, this kind of political consciousness no longer exists at present.
