Extension: What does the paper fund number mean?
Papers are usually closely related to fund projects, which are often some key scientific research projects. With the support of project funds, the thesis is a form of project scientific research achievements, including topics. Therefore, papers related to fund projects will indicate the fund number in the article.
Generally speaking, it is relatively easy to publish some domestic academic papers funded by fund projects, so it is suggested to number the papers funded by fund projects, even if it is a little easier to publish. Marking the fund number is also helpful for future topics, because so much fund support has finally produced output, which is the embodiment of the results. For domestic journals, many journals also hope that papers will have fund projects, because there are assessments in this respect in the evaluation of domestic journals. This indicator is called the ratio of fund papers. The more papers with fund projects published in journals, the better the evaluation of journals, so it is a win-win situation to link papers with fund numbers.
There is no special requirement for the number of fund numbers, which mainly depends on the actual situation of the article. Some articles will be marked with multiple numbers, and there is nothing wrong with them, which can be in line with the actual situation.

Science Network is the largest comprehensive academic information resource in the world, covering the most subjects. Including the most influential 8850 (SCI)+3200 (SSCI)+1700 (AHCI) core academic journals in natural science, engineering technology, biomedicine and other research fields. The impact factor (IF) introduced by the Science Network has now become a general index for periodical evaluation in the world. It is not only an index to measure the usefulness and exhibition of periodicals, but also an important index to measure the academic level of periodicals and even the quality of papers.
