The position of the first author of sci papers is more important, but many contributors don't know what conditions the first author should meet. I would like to introduce the editor of WOsci Voss: The first author is generally the main author of the paper and the author of the first draft of the paper, while journals like sci have no strict requirements for the author's signature. Students such as graduate students and doctoral students can also be the first authors. As long as everyone's papers are of good quality, it is no problem to be the first author.

In addition, I would like to emphasize here that sci papers attach great importance to the quality of the papers, although there is no requirement for the academic qualifications and qualifications of the first author. The first author is in charge of this paper and is also the main contributor to this scientific research achievement. The first author can even serve as a correspondent, that is, the main person in charge of the project. His main contribution is to provide research funds, test sites, laboratories, instruments and equipment and other material resources related to experiments. SCI paper retouching /SCI retouching editing /SCI paper translation /SCI paper duplication checking /SCI paper duplication reduction.

The first author has made an important contribution to the completion of the paper. For example, he played a key role in the whole experiment, so he can naturally be both the first author and the correspondent. In addition, contributors should also pay attention to the strictness and objectivity of the first author's signature. There will also be * * * in an sci paper, that is, both contribute the same, or students can be the first with their tutors.

In a word, the signature requirement of the first author of sci paper is not high. As long as we take the paper seriously, ensure the quality of the paper and make more contributions, we can sign it correctly, which is helpful for the smooth publication, graduation and promotion of the title.
