Looking back on my undergraduate years, I feel very hard and grateful to be able to successfully complete my undergraduate study under the pressure of study, work and life. Thanks to all the people who supported me, helped me and encouraged me! I sincerely thank my tutor Professor Gui for his agile thinking and keen academic vision, his diligent pursuit of teaching and scientific research in safety discipline, his advocacy of integrating theory with practice, his emphasis on refining scientific problems from the scene, his strict requirements for students without losing his humor, his constant criticism of steel and his concern for parents. During my study, my teacher not only set a good example for me in scientific research and study, but also provided selfless guidance and help; I also give a lot of care and help in my work and life. From the topic selection to the subsequent writing, writing and revision, the teacher devoted all his efforts, and the teacher took pains to give careful guidance and revision. The completion of this paper can not be separated from the teacher's careful teaching and strict requirements. The study with teachers in recent years has laid my attitude towards practice and application, which has benefited me for life! Sincerely say thank you to the teacher!
I want to thank my respected tutor. The teacher has set a good example for me in many aspects, such as being a man and studying, which is worth learning constantly. The teacher's thinking is very good, and his speech is very logical, simple and clear, which can give people profound inspiration; Do things very strictly, do things seriously, be modest and so on. In the undergraduate study stage, the teacher has been asking us with scientific spirit, so that we can clearly understand the relationship between Tao and technique and strictly abide by academic ethics, which has laid a good foundation for my undergraduate thesis writing and future development. The whole process of undergraduate thesis is inseparable from the careful guidance, guidance and funding of teachers. For example, when making a report at a regular meeting, the teacher can always give specific suggestions for improvement. In addition, the teacher treats every student like a child and gives me careful care in life. At the same time, Mr. Yu Xiujin is sincere and amiable, and he also gave me warm care during my undergraduate study.
