First of all, there is a defense link, which is to let the teacher have a more comprehensive understanding of our design, because we need to know that through a simple description of a few minutes, there is no way to convey all the contents of our products to the teacher, so the teacher can't have a comprehensive understanding of our products, so setting such a link can let the teacher ask questions that he is interested in. However, many students did not get a good explanation for this link, which led to the teacher's lack of in-depth understanding, so it did not achieve the expected effect of the teacher, resulting in a situation of only answering without arguing. Therefore, in the process of our defense, we must attach great importance to the defensive link, because this link often affects the change of victory or defeat.
Secondly, the setting of the defense link is also to let the teacher explore how strong our ability is in this respect, because we can't be satisfied with the status quo in the process of learning the subject, and we are required to have a general understanding of the future prospects. Therefore, the setting of the defense link requires the teacher to ask us various questions in this link, examine our improvisation ability and mention some professional knowledge. Let us have a more ambitious plan for our future goals, so the existence of the defense link is to let the teacher have an overall understanding of what we have learned in our college life, and at the same time let the teacher have a deeper understanding of our personal abilities, so that we can judge what a student's future development prospects are, and how teachers should cultivate students' various abilities in the next teaching process.
This defense link is also to make our graduation defense more regular and procedural, because the defense link is originally an interactive link through students' brief introduction and teachers' various questions. If only students discuss, there is no way to study a topic clearly, which is a great loss for some scientific research fields.
