The number of words in the master's opening report is generally not less than 5000 words, but the requirements of each school are different, so it depends on the requirements of each school.

The opening report is an important part of graduation thesis work, which refers to a special written report that expounds, reviews and determines the topic of graduation thesis. It is a forward-looking plan and basis for graduate students to carry out graduation thesis research, an important measure to supervise and ensure the quality of the thesis, and an effective practical activity to cultivate graduate students' scientific research ability and academic writing ability.

In addition, most tutors may not be very clear about the idea of the topic, so they can't tell the students. Some tutors know the direction of the topic, but they don't tell the students in the early stage of the topic selection. Their purpose is to train graduate students' ability of literature research and refining ideas.

It should be reminded that even if the tutors don't have mature ideas about the subject, they often have some original opinions because they have been deeply involved in the research field for many years. As a graduate student, you need to be familiar with the work done by your tutor or your brothers and sisters, and actively communicate with your tutor to discuss the direction of the project. It is much more efficient to determine the theme in brainstorming than to study the literature behind closed doors.

After determining the research direction, the most traditional way to choose a topic is to read Chinese and English literature and get inspiration from previous studies. If the research blank can be found in the literature research (for example, the influence of micropores in the weld on the fatigue characteristics of the welded structure is still in its early stage),

Or controversial research conclusions (for example, some documents think that sodium intake will lead to fluid consumption and increase of vascular contents in the body, but some studies also find that too much sodium intake will not stimulate thirst and fluid consumption, but will promote catabolism and weight loss).

Or it can be combined with new technologies/theories/ideas to improve the existing conclusions (such as cross-study of clinical drug response prediction based on artificial intelligence), so it can be the direction of the subject.

Ideas can't be achieved overnight, but there is a development process. That is to say, we must first determine the generality and backwardness of the research, put forward some preliminary ideas through literature reading and analysis, then test the key elements such as the quality and feasibility of the ideas, then screen out good ideas, and finally optimize them into golden ideas.
