The low repetition rate of papers is a rare problem, because in most cases, we will try our best to ensure that the content of our papers is original. However, if you find that the repetition rate of your paper is too low, it may be because your paper lacks necessary quotations and references. Here are some possible solutions:

1. Add citation: Make sure that you have cited all relevant research and materials. This can not only improve the credibility of your paper, but also improve the repetition rate of your paper.

2. Use more technical terms: Technical terms are usually not found to be repeated, so try to use more technical terms in your paper.

3. Reread and revise your paper: Make sure there is no unnecessary repetition in your paper. For example, if you mention the same point many times in a paragraph, try to simplify or merge it.

4. Use plagiarism detection tools: There are many online plagiarism detection tools that can help you check whether your paper is repeated too much. These tools usually provide detailed reports and point out the repetitive parts in your paper.

5. Seek professional help: If you are still not sure how to deal with this problem, you can seek professional academic writing help. Many schools and universities provide such services, which can help you improve your writing ability, including how to avoid excessive repetition.

Generally speaking, although the low repetition rate of papers may seem to be a problem, it may actually be an opportunity for you to study your topic more deeply and quote relevant research and materials more comprehensively.
