First of all, I would like to thank my tutor, Professor Ban Guining, for his great concern and encouragement for my postgraduate life and study in the past three years. In the process of writing a composition, no matter what difficulties I encounter, like what he said that I don't understand very well, he took the trouble to explain it to me again. I remember that my thesis encountered some difficulties during the summer vacation. After calling him to make an appointment, he came to the classroom to explain patiently until I fully understood. His profound knowledge, rich scientific research spirit and selfless research spirit have a great influence on my study. He taught me how to find problems better, and under his influence, my ability to solve problems has been further improved. In life, he also cares about us. After class, he is not only my teacher, but also my friend, and even more my parents, which makes every day of my three-year life happy and full!

Secondly, I would like to thank Professor Xu from the bottom of my heart. Under his guidance, I mastered the basic knowledge of this major and laid the foundation for future study. His inspiring teaching methods and approachable style have enhanced my self-study ability and cultivated my ability to deal with people better. Thanks to other teachers who have taught me, these are the necessary processes for me to complete my three-year postgraduate study, and I also want to thank Miss Li for her concern and encouragement.

Thirdly, I thank my sister Li Qunlan for her care and help in my study and life, my classmate Liu Hailin and my younger brother for their help in my study and life, and Yang Xu, Wei and Liu Meixing for their help and care in my study and life in the past three years.

I especially want to thank my family and every teacher and friend who silently supports and encourages me. Because of you, I can get what I got today.

Finally, I sincerely thank all the experts for their guidance and suggestions on my thesis.
