It is ok for undergraduates to cite second-hand materials in their graduation thesis, but not all of them can. Everyone should pay attention not to quote too much in the paper, and the citation needs the correct citation format. If you copy other people's articles directly, the duplicate checking rate will be high, which will lead to your failure to graduate smoothly.

Second-hand materials can be used for undergraduate graduation thesis, but the publication time, publications and publishing house information should be indicated so that reviewers can check and review according to the information listed by us.

The second-hand materials cited in the paper are collectively referred to as references, and usually a paper needs to cite dozens or even hundreds of references.

How to determine the number of references in papers

Not the more the better. The number of references is directly proportional to the amount of information in the paper. Some students think that the more references cited, the more the author pays attention to the citation problem and respects the achievements of other authors. Others think that the more references cited, the greater the moisture in the article, which is the so-called patchwork, moderate citation, and just explain your own problems.

If it is a paper that needs to be submitted and you don't know the quantity requirements, you can find an index of "average citation times" in the index of evaluating journals, which can be used as a reference.
