The thesis opening defense (opening report) is similar to the scheme evaluation of scientific research (development scheme, scheme demonstration, feasibility analysis, demand resources and project schedule, etc.). ). The difference is that you have many colleagues to assist you in scientific research, and you are basically faced with people in the industry, and basically have clear design needs. The thesis chooses its own topic, which has a large choice space and no functional and performance requirements; But there are three difficulties: first, the general defense is to fight alone; Second, the teacher who participates in the defense is not an expert on your topic, so don't be too mysterious in language. The plan review will be covered by the face of its own leader, and it will not be too difficult if there are no obvious major mistakes. Third, the paper should have innovative highlights, focusing on the principle and its realization; Scientific research is not necessarily for reference, and the focus is on transforming technology into mass products.
