Reason:

1. There are many words in the master's thesis, which makes students easily stray from the topic, resulting in irrelevant articles, unreasonable sentences and poor quality articles.

2. The research direction is narrow, especially in science and engineering. It takes at least a few months or even a year or two to write a good paper, which consumes a lot of time and risks failure. In this process, accurate calculation is needed. Once a formula is miscalculated, it may lead to the failure of the experiment, and then the paper will have to be rewritten, which may also lead to the extension of business.

3. Lack of innovation. The quality of the current graduation thesis is not high, which is mainly reflected in the lack of solid knowledge, students' lack of theoretical depth and comprehensive ability, and poor ability of independent thinking, investigation, problem solving and analysis, which leads to the lack of novelty, depth and innovation in the research topic of graduation thesis.

4. Reference collection. Many people think it is not difficult to search for references on the Internet. Yes, references are hard to find, but the most professional references are hard to find. In order to make the paper more logical and rigorous, references are essential, but the master's thesis needs not three or five references, each of which should conform to the content of the article. The collection of documents and materials is not a blind search. Although there are many channels to find, finding suitable documents and materials can be described as finding a needle in a haystack.
