1. Theoretically, there will be no problem. The scope of duplicate checking of doctoral thesis is other papers written by graduated doctors, and it will not be found in the National Natural Science Foundation. However, the scope of duplicate checking after the application of NSFC is the database of various funds of NSFC.

However, I suggest that you adjust your language properly before submitting. Generally speaking, the writing style of natural science foundation and doctoral thesis should be slightly different. The foundation should be as concise and profound as possible, and the doctoral thesis should pay more attention to system integrity.

Matters needing attention

It's best to find out the final test system of your school before the duplicate check, and use it to test before the last duplicate check, so that the result is the most correct. The result of inappropriate duplicate detection system is incorrect, whether it is high or low.

The repetition rate of the paper is learned from other people's data and opinions on the original basis, so we should first have our own big framework and structure before starting, and then find the appropriate papers and documents to describe and integrate in the paper.

In the process of losing weight, there are many skills, such as Chinese-English multi-translation, graphic transformation, sentence pattern transformation, synonym substitution and so on. These are small-scale duplicate checking techniques. At the same time, these duplicate contents also need to use more skills, which makes duplicate detection more natural and difficult. In short, no matter how to reduce the weight, you need to delete, fill in and rewrite the existing content after mastering the keywords.
