? Paper duplication checking, that is, repetition rate, that is, the copy rate of words, that is, the ratio of the number of words you quoted to the number of words in your paper, is the detection of academic misconduct documents in colleges and universities. At present, most colleges and universities use CNKI dissertation detection system of China HowNet to check duplicate papers. The school only gives HowNet papers two free duplicate checking opportunities. Of course, we can also pay to check the duplicate through HowNet. However, the cost is high, which is not cost-effective for college students, so we should make good use of these two duplicate checking opportunities to make our papers pass smoothly.

? So what knowledge do you need to know in advance to check the duplicate papers?

? First, check the copy. Every school has different examination sections. Usually, the test part is Chinese and English abstracts, keywords, literature review, text, tables and references. The undiscovered parts include cover, statement, table of contents, thanks, pictures and codes. When writing a paper for the first time, it is necessary to determine the format of the paper and write all the elements of the paper completely, so that there will be no more or less omissions when checking duplicate.

? Second, check the duplicate content. It mainly refers to references, which are an indispensable part of a paper. A paper is a process of argumentation, that is, you cite other people's opinions to prove that you are right, but references cannot be cited indefinitely. The principle of HowNet duplicate checking is that if the same paragraph has 13 characters, it will be marked red and judged as plagiarism. General undergraduate duplicate checking rate is 20%. In recent years, due to the increase of academic misconduct, the requirements for graduation thesis have also increased. It is safest to reduce the duplicate checking rate to 10% or even lower.

? Third, how to lose weight. When you first found yourself with a high duplicate checking rate, how did you lower your weight? Here are some suggestions. We don't have to be exactly the same as what is quoted in the paper. We can find out the meaning of the original text first, and then reorganize the expression in our own language. If it is still difficult, then synonym substitution and word order adjustment are very useful skills.

? Many students with high duplicate checking rate have almost no own language because of a lot of copying and pasting in their papers. As long as they carefully prepare papers, collect a large number of original materials, arrange materials and have their own thinking, I believe it is not difficult to write a paper with low duplicate checking rate. So students, work hard.
