Many graduates have to write papers to thank them, which shows the author's grateful moral sentiment and modest academic spirit. Let's write a thank-you paper together. There are many precautions in the thank-you speech. Are you sure you can write it? The following is my thanks to you for collecting the engineering cost papers (five selected papers), hoping to help you.

Thanks 1 Time flies, my three-year master's career is coming to an end. During these three years, my tutor and professor gave me a lot of help and guidance. Whether in school or in life, the existence of teachers is like a mirror, which allows me to see myself, find myself and make myself better. Teachers will not often appear in my daily life in the future, but I will keep this mirror in my heart and always take it out to remind myself and restrain myself. Thank you, Miss Jin Xin.

At the same time, I am also very grateful to Director Tang Yong, the corporate tutor. During more than one year's internship, Director Tang was very concerned about my internship and gave me great help in selecting topics and arranging papers. Director Tang is knowledgeable, positive and optimistic, humorous, and has given me a lot of guidance and help in my life and work, which has taught me a lot of experience in being a man and doing things. Thank you very much, Director Tang!

Thanks to Dr. Cai Qingmin, the director of the Institute, and Senior Brother Gao, the leader of the acetic acid hydrogenation project team. Thank you for your strict requirements and inculcation, which enabled us to complete the transformation from naive students to mature workers as soon as possible. Your profound knowledge, meticulous spirit and mature working methods are worth learning.

Special thanks to the Zhang Jinzhong brothers. During my internship, I benefited a lot from his words and deeds. I not only learned a lot of experimental skills and chemical knowledge, but also broadened my horizons and learned a lot of ways to deal with people. Zhang Ge's serious attitude towards the project, professional knowledge and overall thinking are all worth learning. Thank you very much, Brother Zhang!

You can point out the shortcomings in my work in time and help me solve the doubts in confusion. Thank you for helping me in my study, work and life, and promoting our progress.

Thank you for your project cost paper II. Another graduation season. I remember when I first came here, I stepped into the campus with fantasy. I hope to enrich myself and strengthen myself in this field ... In this way, three years of college, like a gust of wind, came to an abrupt end. We should leave school, just like birds. We should learn to fly by ourselves and go out to find food by ourselves. Here, I sincerely thank my tutor Xiong Dan, and thank you for your sponsorship of my studies! Thank you for your meticulous care in life! And my dear classmates, thank you for your company along the way! Let my college life be so rich and colorful!

The work of this thesis was completed under the careful leadership of the tutor, and my rigorous academic attitude and scientific working methods gave me great sponsorship and influence. I sincerely thank Mr. X for his concern and leadership in the past three years.

The graduation date is approaching day by day, and the three-year study life is decreasing day by day. Thanks to the teachers who have taught me in the past three years, they not only satisfied my thirst for knowledge in college, but also taught me the truth of life and interpersonal skills. At the end of this paper, I would like to extend my sincere thanks to all the teachers and classmates who care about and help me.

This thesis has been helped and supported in many ways from conception to completion, especially thanks to my tutor Mr. Yu Hai for his careful guidance, rigorous academic attitude and scientific working methods, which have greatly helped and influenced me.
