The first author and correspondent author have the highest weight, followed by the second author. Sanzuo and Sanzuo have relatively low weights, so they are basically the same name. The weight of the two works is still quite high, which can be counted as your academic achievements.

The difference between one job and two jobs:

1, with different gold contents.

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.

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 important charts (that is, physical contributions) to the article. The second and third authors sign after the first author in descending order of contribution value.

3. Different responsibilities.

The first author is usually the main executor of the specific work and the writer of the first draft of the article (that is, the intellectual contribution to this article). The responsibility of the second author is also after that of the first author.
