毕业论文答辩优秀展示

医学毕业论文答辩

各位老师，上午好!

我叫魏巧莲，是2006级**班的学生，我的论文题目是《中药提取液絮凝流体动力学的研究》。论文是在康勇导师的悉心指点下完成的，在这里我向我的导师表示深深的谢意，向各位老师不辞辛苦参加我的论文答辩表示衷心的感谢，并对三年来我有机会聆听教诲的各位老师表示由衷的敬意。

下面我将本论文设计的研究意义和主要内容向各位老师作一汇报，恳请各位老师批评指导。

首先，我想谈谈这个毕业论文设计的意义。

絮凝法用于中药液的澄清处理具有良好的发展前景，可以减少工序、极大缩短生产周期，节约原料降低成本，并且可以有效保留多糖等类的有效成分;且制剂不吸潮、稳定性好。而乐仁堂的养阴清肺糖浆生产工艺中的关键步骤即在其提取液的澄清工艺上，原工艺采用的醇沉法不但生产周期长(低醇型与无醇型产品的澄清周期占整个生产周期的1/2强)、耗费大量的能源、操作复杂而且有效成分损失严重，已无法满足日益扩大的国内与国际的市场需求。本课题主要是以养阴清肺糖浆为处理对象，用烧杯絮凝实验法对其水提液和醇提脱醇液的絮凝澄清过程进行絮凝剂的筛选和絮凝工艺条件的确定，以达到缩短养阴清肺糖浆的生产周期，从而降低其生产成本的目的，并根据实验过程中观测到的絮凝现象探求中药液的絮凝机理，促进絮凝理论的发展。另外，由于水力条件对絮凝过程的优化有着不可忽视的作用，进一步根据实验结果考察分析轴向流和轴径混合流对中药液絮凝效果的影响，同时考察与分析自设计格栅式挡板扰流型式对絮凝效果的影响，为今后中药生产过程现代化的工业化进程提供有益参考资料。

其次，我想谈谈这篇论文的主要内容。

1、采用混凝烧杯实验针对养阴清肺糖浆的水提液和醇提脱醇液分别进行实验，筛选出合适的絮凝剂，并在絮凝剂的最佳用量和最佳药液温度下考察搅拌强度与时间对絮凝效果的影响。

2、从絮体的形态、尺寸及其沉降特性着手，结合絮凝机理，分析水力条件对絮凝过程的影响。

3、考察六直叶圆盘涡轮浆和三斜叶涡轮浆在搅拌过程中产生的径向流和轴径混合流对絮凝效果的影响，并与格栅挡板扰流装置的絮凝效果进行比较与分析，确定能够强化絮凝反应过程的流场形式;最后分析反应器内水流状态对反应器内絮体含量分布的影响，以便研究格栅挡板在絮凝反应中快速混合的程度。

最后，我想谈谈这篇论文存在的不足。

由于客观条件和自身理论知识、研究视野和实际研究水平的有限，在本研究中还存在很多的不足。

答辩前的准备工作：

(一)全力消化自己所写的论文

答辩是学校对硕士论文成绩进行考核、验收的一种形式。研究生要明确目的、端正态度、树立信心，通过硕士论文答辩这一环节，来提高自己的分析能力、概括能力及表达能力。在反复阅读、审查自己硕士论文的基础上，写好供20 分钟用的答辩报告书特别要注意以下几点：1、突出选题的重要性和意义。2、介绍论文的主要观点与结构安排(这部分只说明标题就行，不要论述内容，因老师已经看过你的论文)。3、强调论文的新意与独创性。4、说明做了哪些必要的工作。由于答辩同学太多，现阶段学院还没有开展用PPT，以后，随着规范化，同学们要制作一个图文并茂的简要的提纲，这篇报告书尽量读熟，达到脱稿，照着讲稿或者PPT直接念，效果会比较差。

(二)物质准备

准备参加答辩会所需携带的用品：1.硕士论文的底稿。2.答辩报告书。3.主要参考资料，答辩时虽然不能依赖这些资料，但带上这些资料，当遇到一时记不起来时，稍微翻阅一下有关资料，就可以避免出现答不上来的尴尬和慌乱。4.记录用稿纸。以便把答辩老师所提出的问题和有价值的意见、见解记录下来。通过记录，不仅可以减缓紧张心理，而且还可以更好地吃透老师所提问的要害和实质是什么，同时还可以边记边思考，使思考的过程变得很自然。(以后要准备PPT以备辅助介绍)。 5.着衣冠整洁、庄重，男生穿短袖衬衣，最好打领带，女生穿着尽量职业化些的为好。着衣能给答辩老师一个最直接的印象____你对答辩的重视程度。

(三)调整好心态

要进行答辩，首先就要明确论文答辩想考察研究生什么。硕士教育重在训练科学的思维、如何将科学成果转化为学术文章甚至是创造社会效益。因此，通过论文答辩可以考察到如下：1.论文的真实性。实事求是乃科学研究的基础，论文本身必须真实可靠，弄虚作假难逃答辩委员会专家们的火眼金睛。如果在这方面出现问题，论文势必不能通过专家评审。2.考察相关知识与应用能力。3.考察研究生的综合素质.包括答辩者的表达能力.。成功的演讲是自信和技巧的结合，扎实的专业知识和细致周到的答辩准备工作是成功的前提。使用一些答辩技巧也不可缺少，可以充分展示整理研究材料、展示研究成果的能力，让别人知道自己都做了什么。要想这场战争获胜，就必须对答辩的目的、程序、可能遇到的问题及解决方法进行深入剖析，做到胸有成竹，不要紧张，要以必胜的信心，饱满的热情参加答辩。

一、论文讲述中的常见问题

1、仪表不够得体

上场答辩，要求答辩人仪表不仅要整洁，而且要得体。问题主要是个别女生不够得体，例如过度化妆，浓妆艳抹，不像是参加学术活动，倒像是参加舞会或相亲会。男生装束打扮也可能出差错，例如有男生戴项链出场答辩，显得怪异，不够庄重。

2、仪态不够从容

面对台下众人，尤其是面对众多教师，仪态不够从容，甚至神情慌乱，声音发抖，眼睛不知往何处看，低头不敢看台下，或看窗户外或天花板以躲避，手足无措，站立不正，或不自然扭动或走动。有的笑不像笑，硬挤出来的笑，很不自然，甚至比哭还难看。或者，死死盯住台下某人，令双方都很不自在。或者说话不流畅，犯语病。

3、声音语速问题

个人音质不由自己定，但声音高低由自己定。有的学生声音太高，如同吵架;有的学生声音太小，如同蚊子在叫，连坐在最前排的教师都听不见，遑论坐在后排的人;更有甚者，简直是用鼻子发音，像是在哼哼。语速，则语速偏快说不清楚的多，语速偏慢不连贯的少。

4、时间把握不准

讲述论文时间太短或偏长。短的，只有1分多钟。报过论文题目，然后说分为若干章，第一章是什么，第二章是什么，直到最后一章是什么，接下来便无话可说。长的，则超时，一般是念论文原文。念论文原文，七、八千字的论文，也得半个小时左右，一万五千字左右的论文，得一个小时左右。讲述论文限定时间十分钟之内，时间到了，才念了个开头，主持教师不得不叫停。

5、讲述不流畅

多数学生不能脱稿讲述，而是念稿子，有的念都念不利索。稍微好的，则是背稿子，不是讲论文，而是背课文。最不好的，是念论文。背论文的情况则显特殊。曾有一名学生把7000多字的论文背下来，背诵约26分钟，一字不差，一气呵成，反映该生记忆力奇好而且对论文极其熟悉，但严重超时，因为讲述应该在10分钟以内。

6、其它问题

例如支持手段不足，缺少挂图，甚至连个目录挂图都没有。还有吐字不清，普通话不标准等问题。综合问题，则是一个学生同时出现上述两方面甚至更多方面的问题。例如，一名男生，上台后从头到尾一直埋着头，恨不得钻到讲台之下，念稿子，声音很软很小，哼哼唧唧，好不容易才把论文“哼”了一遍，严重超时。

二、回答提问时的'常见问题。

1、回答问题态度不积极

避重就轻，绕开主要的、复杂的问题，捡非主要的、容易的问题回答，或者，对需要重点详细回答的问题只作粗略回答，对只需要简略回答的非重点问题作冗长的回答。回避问题，对某些问题避而不答，不作任何交代，好像这些问题不曾提过一样。表情或语气显出不耐烦，等等。

2、老问题都回答不好

有时候，多个学生写相同或相近的论文题目，可能被问到相同或相近的问题。有的问题，前面学生答不好或答不上来，按理，后面的同学被问到同样问题，应该比前面的学生答得好，但实际情况有时是，前面同学回答过的问题，后面的人还答不好，令人失望。例如，“策略”的定义是什么，第一个学生回答不了，过一阵第二个学生还回答不了。

3、回答问题数量少

大学生毕业论文答辩，属于本科或专科层次，不同于硕士生或博士生等的毕业论文答辩，问题不会太多，一般每生被提问5个左右问题，回答至少3个问题即可。问题是有的学生只回答2个甚至1个问题，或者只能答好1个问题，数量太少，占问题总数比例太低。

4、答案有缺陷

答案不完整，例如某学生写关于中国—东盟自有贸易区的论文，回答“东盟包括哪些国家?”时，列举目前东盟国家名称与数量，与标准答案相差不多，但毕竟不完整。回答“中国与东盟哪些经济体经济往来最多?”时，缺陷更大。某国际商务专业毕业生撰写的论文题目是党政官员带病提拔问题，不仅文字内容没有向商务领域倾斜或靠拢，回答问题时也对商务领域党政官员带病提拔的问题浑然不知，对商务部高官被捕概不知晓。某学生撰写有关企业家能力的论文，但该生不仅没有在论文中对著名企业家进行列表分析对比，而且连国内最著名的企业家都数不上几个来，连大名鼎鼎的海信集团的负责人是谁都不知道，显然相关知识不足。

5、答案不正确或答不上来

某学生论文一再提到我国沿海发达地区，回答“沿海发达地区如何界定?”时，答案不正确，因为其答案是“沿海地区就是发达地区”。实际上，沿海也有不发达地区。

某学生写地理文化对FDI(外商直接投资)的影响，回答“外商直接投资与间接投资的区别有哪些?”时，无言以对。还有商科专业毕业生不知道WTO的全称是World Trade Organization，更有甚者，连三个单词中的一个都说不出来。

6、答案根本错误

例如写“孙子兵法在市场营销中的应用”，回答问题时答“孙子兵法第36计”云云，把孙子兵法与三十六计混为一谈，违反了起码的常识。论文写兵法，却连孙子兵法与三十六计都分不清，缺乏起码的常识，犯了原则性错误。

还有，写区域经济问题，论文中贯穿着“长江三角洲”的用词，讲述中也一再提到“长三角”、“珠三角”如何如何，但被要求回答“什么是长三角?”这样简单的问题时，却一再说长江流域如何如何，原来该生连长三角与长江流域都分不清，经教师现场提示，仍然不清醒。论文主题词都根本理解错误，而且大错特错。

7、对论文摘要英译不熟悉

400字左右的中文摘要，翻译成英语，篇幅会有所增加，但不会增加太多，作者应当十分熟悉。但实际上，有的作者不熟悉自己论文摘要的英语翻译。例如，中文摘要中出现“金融危机”，摘要英译中也有“financial crisis”，但被问及“金融危机”如何翻译成英语时，却答不上来，只回答说自己英语底子不好。类似还有“central government”、“local government”、“furious market competition”等等，都是出现在论文中，但作者答不上来。这种情况下，翻译工作往往不是作者自己完成的。

8、其它问题

例如，审题不清，答非所问。过度回答，画蛇添足。胡蒙乱撞，信口开河甚至狡辩、强词夺理等。

教师看到论文摘要英译篇幅明显短少，并发现有整句甚至整段没有翻译，属于偷工减料或粗心大意，于是提出疑问，有的学生回答是意译，不肯承认是自己工作不足。

就是简要概括你的整篇论文的整体框架，写作思路等。PPT要简洁，字数不宜太多。有13左右就差不多了。PPT最后最好写上致谢，而且要说出来。个人看法。。。。呵呵。

1.在十分钟的陈述中，该生介绍了论文的主要观点、内容与结构，以及论文的写作过程，条理清晰，语言无大错，对老师的提问做出了基本正确的回答，体现了一定的专业素养。但设计过程有点小问题，流程图不很完善，希望及时纠正。 2.从答辩可以看出该生总体专业基础比较扎实，准备工作充分，对论文内容非常熟悉，能简洁明了的陈述设计思想和过程，系统展示流畅，回答问题有理有据，基本概念清楚，论文有一定创新。希望继续完善论文中的部分文字和符号，争取规范使用。 3.该生在规定时间内比较流利、清楚的阐述论文的主要内容，能恰当回答与论文有关的问题，态度谦虚，体现了比较扎实的计算机基础。建议把图像的打开功能用适当的文字表达出来，继续完善使论文格式规范化。 4.结合数学知识用计算机技术来处理地质问题，对方法原理掌握透彻，论文有比较好的创新。对快速傅里叶和小波变换图的结果分析到位，处理结果良好，计算机基础素养好。答辩中主要问题回答准确、深入。论文中变换的指标若有对比会更好。 5.论文陈述清楚，讲解简单明了，存在不足在于缺少自己的新观点、新方法，多为套用他人研究成果，论文格式方面应多规范。 6.答辩的准备工作充分，对老师的提问能详实回答，并对设计过程中所遇困境能反复探讨研究，找出更好的解决方法，专业技术比较好。若能结合专业改进使静态的网页成为动态的则更好，不足在于数据库中表的描述方式不太对，望改进。 7.论文陈述清晰明白，开门见山，直接入题。对老师的提问能流利作答，思路清晰，但对论文中的部分代码解释不楚，有少量语言错误，望今后的研究中多创新。 8.该生能在规定时间内陈述论文的主要内容，但答辩中回答问题不是很流畅，对设计的细节技术不太熟，回答问题不够切题。 9.从五部分对论文进行阐述，重点突出，答辩流畅、熟练，知识掌握基本到位，时间符合要求。不足是论文中有部分概念错误。 10.答辩过程中，该生能在规定时间内熟练、扼要的陈述论文的主要内容，条理清晰，创新点明显，回答问题时反映敏捷，表达准确，系统演示熟练，专业素养很高，经答辩委员会商议，一致同意其成绩为优秀。 11.在五分钟的陈述中，该生介绍了论文的`主要内容与结构，以及为此进行的研究，显示出对所研究的问题有一定的认识。视频设计很漂亮，但不太符合专业要求，若多从计算机专业的角度对实现过程进行设计则更好。 12.该生流利地陈述了写作该论文的目的、理论与实践意义，古玩网站设计过程很规范，但实体和概念之间联系少，整个设计应该尽量符合计算机方面的要求。 13.该生陈述清楚，回答问题流利。虽论文立意比较好，有一定的研究价值，但构架和内容都比较庞大，需要较强的独立研究能力，论文题目和客户端登陆服务器模块也需稍作修改。 14.该生准备工作充分，环节陈述完整，论文构思清晰，体现了较好的专业基础，时间把握也很好。就是论文中有需求但缺乏需求分析，对部分答辩问题回答不太清楚，图的表示方式不规范。 15.该生用dreamweave和access数据库等技术对甘孜旅游网站进行设计，设计清新美观，主要问题回答准确，基本概念清楚，望对论文中指正的数据库存放问题进行修改。 16.该生专业素养比较好，对所提问题回答流利，正确率高，对实现过程中遇到的难题认识到位，时间把握得当，若能用比较新的运行环境进行实现相对好。 17.该生对数据库的设计细节讲解详细，研究深入，论坛设计部分独立完成，有一定的科研能力，答辩中思路清晰，回答得简明扼要，语言流利。答辩组经过认真讨论，一致同意通过该生成绩为良好，但要求该生纠正论文中尚存的某些错误。

Good morning,

Distinguished professors and teachers, ladies and gentlemen, thank you for attending the oral defense. (或Welcome to attend the oral defense.) ：

I am Wu Lin. First and foremost, I would like to express my sincere gratitude to my supervisor, professor Hu Anjiang, for his intellectual guidance, invaluable instructions and comments on my thesis. It is with his valuable assistance that I have finally accomplished this thesis.

My topic is On the tragedy figures at historical turning points(Comparison of KongYiji and Rip Van Winkle).

The whole thesis consists of 6 parts. The first part will give a brief introduction of the negative, evasive and conservative attitudes of Kong and Rip as well as the topic’s significance in the real society. And the second part is going to analyze the figures’ background to show the historical necessity of the tragedies. In the third part, the tragic heroes’ failing in the character according to their living environment will be further discussed and the fourth part is to talk about their different tendency of dispositions and behaviors in the society. Then the author will dig into the root causes of the tragedies in the fifth part, and sum up the whole paper to reveal the ideological weak points of the two countries separately in the last part.

Thank you!

good afternoon, all appraiser committee members. i am xxxx and my supervisor is xxx. with her constant encouragement and guidance, i have finished my paper. now, it is the show time. i will present my efforts to you and welcome any title of my paper is on transformation of parts of speech in translation. i choose this as my topic due to the following reasons. different languages have different standards to distinguish parts of speech. each language has its own special structure. and there are no equivalent parts of speech between different languages. in order to make the target version more idiomatic and standard, the transformation of parts of speech is always used by translators. so the transformation of parts of speech is playing a more important role in english to chinese based on different characteristics of english and chinese. for the above facts, i select the subject of“on transformation of parts of speech”as the title of my hope by studying this topic we can know the importance of the transformation of parts of speech in english to chinese translation. through transformation, we can get the better version and improve the translation way of thinking and expressing is quite different between chinese and english. english is a kind of static languages which tends to use more nouns. while chinese is a dynamic one in which verbs are often when we make translation in english to chinese, we should know this point and shift the parts of , it is an outline of my paper. in the main part of this paper, i divide it into five one presents an introduction to the basic concepts of parts of speech and two discusses the definition of translation and emphasizes the importance of transformation of parts of speech in the course of three gives four basic ways of transformation of parts of speech through illustrative examples. there are transformed english words into chinese verbs, nouns, adjectives and four presents some problems about transformation and gives some advise to solve the five draws some conclusions that transformation between parts of speech is necessary for us to achieve good translation. it is demonstrated that we can have a good master of transformation and improve the translation. in addition, we must continuously study and explore in all kinds of translation ! that is all. thank you!

stant encouragement and guidance, I have finished my paper. Now, it's show time. You and I will work hard to welcome any topic of my thesis is 《Angela carter to mythology research - the female archetype in “new eve passion”, for example》。 I choose this as my topic due to the following Carter （1940-1992） is an outstanding feminist writer whose influence on Britishwomen's writing was “pivotal in this opening and transformation” [“23]. The year 2014 represents the 22”^ anniversary of Angela Carter's death. In those twenty-two years, her works have been widely taught internationally and brought about much critical debate. In a survey conducted by Cristina Bacchilega and Danielle M. Roemer [2],Carter is one of the most commonly taught women writers on North American programs. She has endowed us with an amazingly large number of legacies in her comparatively limited life, setting foot in various fields such as novels,short stories,children stories, dramas, non-fictions and so on. The acute observations with great insights,as well as the devastating wit and poignant mockery in Carter's works have made her stand out as an iconic figure in English literature. Many scholars and critics have devoted themselves to the research on Angela Carter from many perspectives,including gothic, magic realism, feminism,post-modernism and so on. As a prolific writer who is always ready to blur the boundaries between different genres, Carter has left us a wonderful world to delve the emergence of western women's movement as well as the development of feminist criticism in the 1960s,the feminist approach has become a potent weapon for those who are concerned with the emancipation and legal rights of women. Though women's social status has considerably improved due to the contribution made by countless predecessors,the fundamental problem still lingers on. Carter, with her versatile and avant-garde reputation, is best known as a feminist writer. Concerning the dilemmas and predicaments faced by women nowadays,it is very necessary for us to probe into her insightful and penetrating reflections on femininity as well as the relationship between two genders. The Passion of New Eve, as one of Carter's most representative works, is of great value in the research of her feminist thoughts and , is my paper outline. In the main part of this article, I put it into five one is an introduction to the thesis, covering the research background, theobjective and significance as well as the organization of the two presents a broad picture of Angela Carter's life and her works, as well as the background information about The Passion of New Eve. It also reviews previous studies on Angela Carter and her works at home and abroad, summarizing achievements in the past and pointing out new directions in the three conducts a retrospective study on feminism and archetypal criticism. The author attempts to work out the origin and development of feminism, demonstrating the important role feminism plays in Carter's life. Then is the history of archetypal criticism,as well as those classic female archetypes in mythology. Regarding those fossilized and monotonous images as impediments to women's freedom and liberation,Carter endeavors to shatter them in her demythologizing strategy and appeals for a rational attitude toward heterosexual four is the main body of the thesis. Through an in-depth analysis on The Passion of New Eve,it demonstrates Carter's demythologizing of “The Temptress,,,”Mother Goddess“and ”Eve“ respectively in the text. Leilah,the embodiment of Delilah,the famous temptress in the Bible,cannot escape the fate of being objectified by men and herself. By exposing”temptresses“ as mere victims rather than symbols of viciousness. Carter condemns the oppression and exploitation of women in a patriarchal society. ”Mother“ in Beulah serves as a severe satire on those mother goddesses in mythology. Carter smashes the legend by revealing the surgically-made essence of mother and the patriarchal values lurking behind her alleged matriarchal kingdom, warning against the peril and impracticality of extremist her most convincing example goes to Eve, the most important female character in the Bible, Her transformative journey from a chauvinist to a real woman in the story illustrates that gender, rather than a hereditary feature, is the result of social influence and unremitting imitations. Carter concludes the story with proposing ”androgyny“ as a solution to the current problems,implying that mutual respect and understanding is the only way to achieve the harmony between the two five comes to a general conclusion, summarizing the limitations of the theses as well as some suggestions for further ! That is all. Thank you!

Good morning, distinguished professors and teachers, thank you for attending the oral defense. I’m xxx and come from class x. My supervisor is professor Li. I would like to express my deepest gratitude to Prof. his consistent guidance and valuable suggestions, I have finished my paper. Now I will present my efforts to you and gratefully welcome any suggestion.

The title of my paper is xxxxxxxxxxxxx. I choose this as my topic due to the following reasons.

Firstly, I am very interested in the study of ambiguity. Ambiguity is a common phenomenon in all natural languages. As is known to all, in our daily conversations, ambiguity is often employed to achieve the effect of humor, thus creating a relaxing atmosphere and letting people feel at ease. Some jokes caused by ambiguity is very interesting.

Secondly, I have read several articles about ambiguity written by linguistics and scholars. I found my knowledge of ambiguity is very limited, superficial and nonsystematic. What I knew is just the tip of the iceberg. So I plan to learn more about ambiguity by this research.

Thirdly, I found many scholars have carried out numerous studies of ambiguity, but a majority of these studies are focused on single language separately. Articles about comparison between English ambiguity and Chinese ambiguity are not sufficient. So it is necessary to make further study.

For the above facts, I select this title.

Next, I will present the outline of my thesis. It consists of 7 parts.

The first part gives a brief introduction to the ambiguity and structure of the thesis.

The second part is literature review, briefly introducing the development of study of ambiguity and some scholars’s main views.

The third to fifth parts focus on three types of ambiguity in English and Chinese: phonological ambiguity, lexical ambiguity, syntactic ambiguity. In every broad type, I respectively list some detailed branches and cite some vivid English and Chinese examples to explain these ambiguity phenomena. But I put more focus on the third part and point out two differences of ambiguity between English ambiguity and Chinese ambiguity.

The part six will point out positive results by using ambiguity deliberately in daily conversations, advertisements and literary works.

The last part is the conclusion.

I hope by this contrastive research, we will have a better understanding of ambiguity in English and Chinese and apply it to our life and study.

When reading the final draft, I still find my argument is not so comprehensive and improvements are needed. So welcome your precious suggestion.

That’s all. Thank you.
