In the professional title evaluation system, the order of papers is usually decided by the author according to his contribution and ranking when submitting. In the process of submitting papers, it is generally recommended to allocate author positions according to the contribution and actual needs. For example, the first author is usually the person who makes the greatest contribution to the paper, and is the actual project leader or main author, while the second author and the third author are usually the people who make certain contributions under the guidance of the first author.
