When scientific research results are written into papers, they will be signed by multiple authors. The scientific community attaches great importance to "fame" Therefore, when signing the thesis, it is a very cautious link. To be completely flawless, all researchers who have made direct contributions to the paper are listed among the authors. This is the hidden rule of scientific research.

If a researcher contributes a paper, but it is not listed in the author's signature, it is easy to break the relationship and the consequences are very serious. The signature order generally represents the contribution of different authors to the results. A work is the biggest contributor to the achievement, often the main executor of the research and the author of the paper, which can be regarded as the soul of the whole research.

Nowadays, many schools stipulate that graduate students must have a good SCI article to graduate and get a degree. Sometimes the contribution of two works can also be tied with one. If it is specially noted that the two works have the same contribution to the paper, the status of the two works can also be improved. But just like patching, it is not as natural as the original ecology.

The signature was heavily watered. Nowadays, it is too common to give signatures as gifts to leaders, spouses, boyfriends and girlfriends, and teachers and brothers. Even those who have not contributed to the research are still listed as authors. This is a false name, it's easy to lift a finger, but it makes people remember themselves. Why not?

It is precisely because of this that domestic academic circles often only recognize one work as the biggest contributor, and graduates or researchers evaluate their professional titles and awards on the basis of one work. The other order is obscene, although it also means contribution, but the academic community generally only looks at it.
