In the academic circle, the first debate and the second debate are two stages for students to reply to academic papers. These two stages have different purposes and requirements, and the differences between them will be introduced in detail below.

The first demonstration of the thesis means that after the students submit the thesis, the tutor or evaluation expert will make a preliminary evaluation to determine whether it meets the defense requirements and whether it needs to be revised and improved. In the first debate of a paper, the judging experts mainly pay attention to the basic structure of the paper, whether the argument is clear, whether the argument is sufficient, and whether the paper conforms to academic norms. If the paper passes the preliminary examination, students can enter the second debate stage of the paper.

The second debate of papers means that students need to make a formal defense of academic papers after the first trial of papers is passed. The second debate of the paper requires students to elaborate and explain the paper in detail, answer experts' questions and make on-site defense. The judging experts will finally decide whether to pass the defense according to the students' defense performance and the quality of the paper.

Therefore, the main difference between the first debate and the second debate is that the first debate is a preliminary review, mainly to determine whether the paper meets the requirements of defense; The second debate is the formal defense of academic papers, which requires students to elaborate and explain in detail and answer experts' questions. In addition, the experts who judge the second debate of papers are usually more strict and have higher requirements on the quality and academic level of papers, so students need to prepare and defend more seriously.

In a word, the first debate and the second debate are two important stages in the defense of academic papers. Students need to take each stage seriously, constantly improve their papers and improve their academic level in order to successfully pass the defense and obtain degrees or honors.
