1, the task is too heavy (light). The research work of graduate students has a year's time, which should be said to be one and a half years if the half year of literature retrieval is counted, which is different from the graduation project of undergraduate course. We should have enough workload, but we should not involve too much and do too much.

2. The theme is too old to represent the current situation of the theme, or it is similar and repetitive to the previous theme. Although the research work of graduate students may not be very innovative, it can't always be entangled in? Traditional problems. In the process of research, we should have a good understanding of the present situation of this subject. At the same time, when reading the materials, students must find the location of their own topics, not always around the content of brothers and sisters.

3. The content of the topic is too simple, and there is not enough research space for graduate students. Some topics have a lot of work, but nothing. Research? Content, which mainly appears in? Engineering? In highly sexual subjects and topics. There are many things like screwing screws and drilling holes, but there are not many academic contents, so graduate students can't play their abilities and can't find the starting point in the research process.

The content of the topic is too difficult and too big. Considering the time and level of graduate students (after all, there is not much research and engineering experience), sometimes a project is greedy. A research project can be decomposed into several relatively independent subprojects, which can be carried out independently, but sometimes there is no integrity when the project is decomposed, and it is too big or too incomplete to produce experimental results, which brings trouble to the follow-up work.

5. The research method is not specific, what is the combination of qualitative and quantitative, and so on. Or write down more than ten methods you have heard.

6. Someone listed more than a dozen research significance and importance in the opening report, but only two or three can be asked; I don't have my own ideas and opinions. That is, there is no serious investigation and serious analysis of the problem. Creative work comes from creative problems, and creative problems come from creative thinking. At least, can you go? Mainstream? Find out the most important part of the importance of each line;
