It is really rare that the duplicate check result is 0, so many students after duplicate check will be surprised to see this result, can't believe it, and will have doubts about the duplicate check of this paper, and even have doubts. In fact, it is normal that the duplicate check result of the paper is 0, but it depends on the specific reasons, because there will be abnormal situations. The paper is highly original, and the graduates have written it independently, and its content is not repeated with many papers. The experimental data in the paper is also obtained by our own experiments, which makes the paper duplication checking system unable to detect the similarities with other people's papers.

Abnormal situation:

1. The format of the paper document uploaded by the author to the paper duplicate checking system is inconsistent with the format that can be detected by the duplicate checking system, resulting in that the duplicate checking system cannot correctly identify and detect it.

2. The content of the paper is a very remote small language, and the uploaded paper duplicate checking system does not contain the database resources of this small language, which leads to the paper duplicate checking system being unable to detect.

3. Plagiarism does exist in the content of the paper, but the database of the paper duplication checking system for upload detection does not have this part of resources, which leads to the paper duplication checking system being unable to detect it.

Many people have a misconception that the lower the repetition rate, the better. This is true to a certain extent, which shows that your paper is original and repetitive with others, which is worthy of recognition. It is not easy to check the weight of the paper for the first time now, which is worthy of recognition.

However, is the repetition rate of paper writing as low as possible? Is the repetition rate best 0? Actually, it is not. Paper writing, to put it bluntly, is the statement and summary of scientific research work. In today's society, no one needs to learn from other people's research results and put forward a new thing entirely on their own. Any research is based on other people's research results, summing up, perfecting and carrying forward, just like Newton said, he stood on the shoulders of giants.

If the repetition rate of one or two chapters in a big paper is below 2%, or even less, it means that this is your core research achievement, and it is possible to innovate independently without reference and related research. But the total repetition rate of the paper is 0, which is not a data error, but a problem with your writing. Thesis writing is regular, similar to stereotyped writing. From research background to research methods, to specific practical operation and theoretical support, it needs to be involved. In this process, we need to learn from a lot of research results of others, and the repetition rate will definitely be there. Everyone must write like this, just as Karl Terzaghi must be mentioned in soil mechanics, and Maxwell's equation cannot be avoided in electromagnetic simulation. When using fractal, you must always mention Mandelbrot, which is a respect for predecessors and knowledge. These are all included in the repetition rate. I think you should repeat even if you repeat.
