What do the letters on the paper mean? This is a question, but also a kind of exploration and thinking. For researchers, letters often represent specific indicators of research results, such as the number of times the article was cited, the published publications, the identity of the author and so on. Therefore, letters mean a kind of honor and achievement, which is the goal of researchers' continuous efforts.

However, for ordinary readers, letters may just be meaningless symbols. In this case, researchers need to describe their research results in concise and easy-to-understand language as much as possible to make it easier for readers to understand and accept. In addition, considering that the research results are often beyond the understanding of domain experts, popular science and popularization are also very important.

In short, both researchers and readers need to understand the meaning and function of letters in the paper. Only in this way can we better promote the dissemination and exchange of knowledge and promote the development of scientific undertakings. At the same time, researchers need to pay attention to the real significance and value of scientific research in the process of pursuing bibliometrics indicators.
