1. The publication time missed the time to report the headline material. The published papers with professional titles are timely.

Any materials submitted one year earlier or later shall be invalid. The selection of professional titles in that year generally requires the papers published in that year to be valid. Otherwise, the evaluation of senior titles is not a paper issued directly with primary and intermediate titles. Some authors did not prepare in advance, published their papers late, and missed the time required by the topic selection department to submit materials, resulting in useless and invalid papers. It takes more than three months for a general publication submitted by an author to be published. For example, it's 65438+ 10 month, but general publications call for contributions in March. If the author wants to submit materials in September, he needs to submit them now.

2. Sign outside the third author.

Most professional title selection departments require the top 3 authors to be valid. If you are greedy, sign more names, and the result is that the author other than the first three signatures is invalid.
