1. Using quotations skillfully, we can clearly find that one of the test reports of HowNet duplicate checking is to remove the repetition rate of quotations, which means to remove the repetition rate of authors' quotations. Usually, no matter in universities or magazines, it will only be identified by the duplicate checking system of HowNet. With the development of the duplicate checking system of HowNet, most citations can be accurately identified, so the author can effectively reduce the repetition rate of this part with a little citation skills.

2. Reducing the repetition rate also requires skill. HowNet duplicate checking is divided into chapters. In the process of duplicate checking, a certain comparison must be made, and then whether there is a continuous similarity of 13 words with the articles in the duplicate checking database of HowNet is detected according to a certain sentence. If there is such a similarity, HowNet will definitely judge that this part is repeated. That is to say, the author should follow the duplicate checking rules of HowNet, try to avoid the text of 13 being identical with others' content, and understand the original intention first before expressing it in his own words in the process of revision, so as to effectively reduce the repetition rate.

3. For some tables and codes, we can use pictures to replace the original articles, but there is a disadvantage, that is, if pictures are used to replace tables or codes, the number of words in the full text will be reduced, so if there are articles with word requirements, we should pay attention to this, avoid repetition rate and have enough words.
