同學們在完成畢業dissertation參加答辯前都需要再寫一份致謝。當下致謝已經是是一篇完整畢業dissertation必不可少的部分了。dissertation中的致謝是作者對dissertation寫作過程中，對于為dissertation做出過指導貢獻的導師、同學、家長、朋友的一種禮貌和尊重。那致謝詞應該怎么寫比較好呢？
其實，不管是國內還是國外留學的學生寫致謝都是一樣的。都需要注意一下這幾點
      1首先是自然對dissertation指導老師的感謝。感謝方向一般可以是導師對本dissertation的貢獻及對dissertation作者的教導、影響。
      2其次是對幫助過你做試驗或者查資料的師兄、師姐、同學、師弟、師妹、朋友的感謝。
      3感謝您的家人、朋友對您的dissertation寫作及學習期間的無私的支持和鼓勵。
下面就為大家提供一篇中英文對照的致謝范文，共大家閱讀參考

       首先，我要真誠感謝TED，感謝他在本人寫作這篇畢業dissertation的漫長時間段內的指導。尤其感激，她會檢查項目中每一處細節并提供我有用的建議直至整個研究完成。我的導師在提出錯誤問題和解決的整個過程中都給予了我慷慨的幫助。如果沒有導師的幫助，我也不可能完成合適水平的dissertation。此外，替學生設身處地的思考讓我覺得她還是一個富有人情味的好導師。導師能理解學生，鼓勵學生并始終提供有益的幫助。我很榮幸能在寫作過程中得到TED的幫助。萬分感激。
       在這里我也要感謝那些一直在鼓勵我,支持我的人們。沒有他們的信任和幫助，我也不會有完善這份dissertation的強烈動力。感謝大家。
