I suggest you refer to the passing situation of your former seniors, and you should look for them in your department, such as graduate students in your department.

If it is very strict, I personally suggest doing an experiment. The upstairs said that there is less time to play, but in order to pass the defense, let's do the experiment. The data and results obtained are true, and the answers to questions will be more targeted.

If the defense is not very strict, as long as it is not too rubbish (it was cramming at that time, and it was done by the efforts of the brothers), you have a certain understanding of professional knowledge, and you can pass it by saying a good word to the teacher after you finish it, then sum it up.

PS: I majored in chemical engineering and technology. I graduated in 2002. Go out to look for a job (more accurately, go out to play) some time before graduation. When I came back, I found that I didn't do anything, and I still had a week to reply. Our project is designed by a four-person team with an annual output of 65,438+million tons. The data is basically inferred by my brothers, and I drew the picture myself. Then I told the teacher.
