Combined with the knowledge learned, through consulting the reference materials, the preliminary design will be submitted to the tutor for review and approval, and then XXX will write the design task book and other materials. Finally, I want to talk about this paper and my own shortcomings.

Because of my shallow knowledge and insufficient cognitive potential, my understanding of some problems is biased and shallow, and because of my weak theoretical foundation, there are many illogical and unsatisfactory words, and many problems need further thinking and discussion.

I sincerely hope that all teachers can put forward valuable opinions and point out the mistakes and shortcomings of this design. I will be open-minded to understand, so as to further study and study, so as to improve and perfect this design. The above is my defense self-report, please give your valuable opinions, thank you!
