Repetition rate detection system is only a means to manage the quality of the final results of the paper, and because there are unsolvable technical problems in the detection system, if we blindly rely on it, it will bring negative effects.

First of all, schools and tutors should understand the function of the repetition rate detection system, that is, the repetition detection system is only an auxiliary tool to test the quality of papers. The detection results of excessive repetition rate only show that there may be improper citation and plagiarism in the paper, but it cannot be used as an absolute basis for academic dishonesty. The standard for evaluating the quality of a paper is still its academic level. Only when schools and tutors can objectively look at the results of repetition rate detection, can we formulate management system more scientifically, guide students to clearly set the purpose of repetition rate detection system in the process of thesis guidance, turn their time and energy to the content of the thesis itself, and realize that only papers with innovative ideas, fluent writing, clear logic and reasonable methods can truly achieve low repetition rate.

Secondly, optimize the design of repetition rate detection system and give full play to its positive role in paper quality management. First, it is suggested that the detection time be advanced. The examination time of undergraduate graduation thesis is generally arranged before the defense. Only those who meet the standard of text reproduction are eligible to participate in the defense, and those who fail to meet the standard are allowed to modify and participate in the supplementary defense within a limited time. This ending arrangement invisibly causes psychological pressure to students, and some students even make irrational behaviors because of great pressure, pay attention to repetition rate and ignore academic norms and paper quality, and even take advantage of illegal business such as revising papers and ensuring passing exams. If the initial examination can be set as a voluntary examination, the time can be advanced to the mid-term examination or the first draft of the paper, which can not only urge students to complete the full text of the paper as scheduled or ahead of schedule, but also help students find the problems in the paper with the help of the examination results and make serious revisions; Tutors can also find problems in time, correct them in time, and really play the role of duplicate checking system in improving the quality of paper writing.

Duplicate checking is to establish a quality evaluation system of undergraduate graduation thesis with manual evaluation as the main part and system identification as the auxiliary part, and to change the practice of applying one-vote veto to the detection results of repetition rate. Based on the fact that the repetition rate detection of undergraduate graduation thesis is only an auxiliary tool to evaluate the quality of thesis, and its result can not be used as the only indicator to judge whether students postpone their defense, the school should set a floating range of repetition rate. After testing, the graduation thesis whose text is up to standard but within the floating range should be submitted to the defense committee or the thesis guidance working group for manual evaluation, or the students should take part in the defense first, and judge whether the students meet the graduation requirements according to the defense situation and the manual evaluation of the thesis.

2. Give full play to the positive role of tutorial system in the quality management of undergraduate graduation thesis.

Different from the standardized academic exercise led by the tutor at the beginning of the postgraduate stage, undergraduates usually begin to contact academic writing after they start writing their graduation thesis in the last year of university, and it is at this time that the tutor really begins to intervene in the guidance of students' academic norms. However, in this short year, various activities such as study, postgraduate entrance examination, textual research and job hunting are intertwined, which makes students unable to concentrate on writing their graduation thesis and cope with their unfamiliarity with academic writing, and the quality of undergraduate graduation thesis is naturally affected. The cultivation of undergraduate students' academic research ability is a gradual process, which needs to start from the first year of college and run through the whole four years of study, and the undergraduate tutorial system is helpful to realize the goal. Many colleges and universities introduce tutorial system in undergraduate course, guiding teachers to participate in students' course selection guidance, professional cognition, subject competition, college students' entrepreneurial innovation projects, graduation thesis guidance, graduation practice, postgraduate entrance examination, employment consultation and so on. With the help of tutorial system, undergraduate graduation thesis guidance can be advanced to the third year of college, laying a solid academic foundation for the high-quality completion of graduation thesis.

First of all, teachers are encouraged to consciously exercise students' academic research ability from the first year of college. During college, undergraduate tutors can let students participate in the research work of their own topics, organize group discussions in combination with professional knowledge learning, guide students to pay attention to academic frontiers in professional fields, exercise their academic thinking, cooperate with literature retrieval courses, teach students to collect and consult documents, help students find suitable topics according to their own interests, prepare literature reviews, collect data and cases, and determine research methods. If you make full academic preparations for your graduation thesis in the first three years of college, you can avoid the phenomenon of coping with the completion of the thesis.

Secondly, the tutorial system combining encouragement with supervision is implemented. Although tutors play an important role in the formation of students' academic literacy, some teachers hold different opinions on whether to strengthen the cultivation of undergraduates' academic research ability, and think that the cultivation of academic literacy is mainly aimed at graduate students and undergraduates who are interested in postgraduate entrance examination; Moreover, unlike the postgraduate tutorial system, the undergraduate tutorial system has no clear academic training plan, and the incentive and assessment mechanism is a mere formality. Tutors often ignore the cultivation of undergraduate academic literacy, which makes the undergraduate tutorial system not play a role in the quality management of graduation thesis. Therefore, it is suggested that the cultivation of students' academic ability should be refined into an important task of undergraduate tutorial system, the responsibilities of tutors should be clarified, the corresponding incentive and assessment system should be formulated, the enthusiasm of teachers to cultivate undergraduate academic research ability should be improved, and the role of tutors in the quality management of papers should be implemented by tutorial system.
