1. Understand the requirements of the journal: First of all, you need to read the author's guide of the submitted journal carefully and understand its requirements, such as the number of words, format and citation method. This can help you ensure that your paper meets the requirements of the journal, thus improving the probability of the paper being accepted.
2. Reorganize the paper structure: Dissertations and periodical papers are different in structure. When rewriting a dissertation into a periodical paper, it is necessary to readjust the structure of the paper to make it more in line with the requirements of the periodical paper. For example, you may need to move some parts to other parts, or merge multiple parts into one article.
3. Extract the essence: Journal papers usually don't need to contain a lot of details and secondary research results like dissertations. Therefore, when rewriting a dissertation into a journal paper, you need to extract the essence and keep only the most important results and conclusions. This will make your paper more concise and more conducive to readers' understanding and acceptance.
