Scientific integrity, generally referring to behaviors and best practices that conform to research ethics, is the inherent requirement and important guarantee of scientific and technological activities, and academic code are the basis and prerequisite for high-quality higher education and scientific research. The frequent occurrence of scientific misconduct in recent years shows that in the training of scientists and engineers in the future, the necessity and importance of scientific integrity and academic code education have become increasingly prominent. First of all, at the idea level, students should be allowed to understand basic scientific ideas and scientific and technological values, and understand the importance of honest, objective and responsible learning and research. Secondly, at the knowledge level, we should help students master the basic requirements of scientific integrity in the whole process of scientific research and understand the basic content of academic code. More importantly, at the practical level, specific suggestions should be made for students' confusion and misunderstandings in ideas and understanding, so as to encourage them to be more honest, responsible and credible in their study and research practice. For science and engineering students, Systematic training on scientific integrity and academic norms not only helps students to better abide by academic code and prevent scientific misconduct, but also make sense to students’ academic honor and social responsibility.
