It is a good academic achievement for graduate students to publish periodical papers during their school days. First of all, you need to choose a suitable periodical, which should be the core periodical related to your research direction. Then, you need to write a high-quality paper, which is innovative and readable enough. Next, you need to submit your paper and wait for feedback from the reviewers. If the reviewer thinks that your paper meets the requirements of the journal, it will be accepted and published in the journal.
