1, the first author refers to the person whose signature ranks first, and some articles have two or more first authors, which are called tied first authors. In this case, it is generally necessary to indicate the name of the person.
2. Second and third authors: contributors who have made direct or indirect contributions to the works, whose overall contribution is far from that of the first author, are collectively referred to as second and third authors.
3. Correspondence author: generally refers to the person in charge of the whole project, who is responsible for the funding, design and writing of the project.
Difference:
1, different components
When the signature of a paper is used in the evaluation of professional titles, the power of the first author is heavier than that of the second and third authors, but lighter than that of the personal signature. The scores of the first author, the second author and the third author of the paper decrease in order of rank.
In most cases, the correspondent and the first author are the same person. Only when the correspondent and the first author are inconsistent, you need to add a correspondent.
2. Different contributions
The first author is generally the researcher who has made the greatest contribution to the work of this paper, not only contributing the most and most important charts (that is, physical contributions), but also writing the first draft of the article (that is, intellectual contributions). The second and third authors sign after the first author in descending order of contribution value.
The first author is different from the correspondent and creative contribution, and the correspondent often acts as the most authoritative person in the field of papers.
3. Different responsibilities
The first author is usually the main executor of the specific work and is responsible for the main experimental results.
Correspondents are the contacts of articles and research materials, and the most important thing is to be responsible for the reliability of articles.
