英语里毕业答辩怎么说

In English, a "graduation defense" or "thesis defense" is commonly referred to as a "dissertation defense" or simply a "defense." It is the final step in the process of earning a graduate degree, during which a student presents and defends their dissertation or thesis, which is a long research paper or project that is the culmination of their academic work in a particular field of study.
During the defense, the student will typically present their research findings and arguments to a panel of experts in their field, who will ask questions and evaluate the quality and significance of the work. The defense is an opportunity for the student to demonstrate their understanding of the research process and their ability to think critically and independently about their topic of study. It is also an opportunity for the panel to provide feedback and guidance to the student, and to help ensure that the research meets the standards of the academic community.
