2, or preaching.

3. After selecting the scientific research topic, explain the present situation, existing problems, research objectives and methods of this topic.

4. Opening a topic is an essential part of graduation. Unsuccessful opening a topic will directly affect the later scientific research work. The elimination rate of many schools is still 10%. If there are 40 students in a class and 4 students can't pass at one time, prepare the second question. If the topic is not opened in time, the big thesis will not be submitted for review, which will directly affect graduation.

Please pay attention to the first few points:

1, the topic should not be too long, and it is best to express the core work of the paper with the least engineering terms within 20 words;

2, try to finish in one sentence, don't turn into two sentences. This sentence pattern often appears in government work reports, but it should not appear in the title of the paper. For example, the title of the report of the 17th National Congress of the Communist Party of China is "Hold high the great banner of Socialism with Chinese characteristics and strive for new victories in building a well-off society in an all-round way";

3. Avoid using verb-object structure. The tone of the verb-object structure is relatively strong, as written in the second point of the government work report, but the paper is not needed. What the paper needs is a simple and clear description of the facts;

4. It must have a lot to do with your keywords. You must be able to see your work at a glance through the title of the paper. Keyword is also a brief summary of the research work, so the title of the paper must be closely related to your keywords.
