可以和你的导师商量换个题目
原因可能有以下几点：动力不足。写论文完全靠自己的自主自觉，如果没有几分好奇心和解决问题的魄力，这论文肯定是难以完成的。情绪不对。始终带着一种“不想写”的抗拒心理，有空闲的时候经常是刷刷微博、刷刷抖音、逛逛淘宝、追追剧、聊完qq聊微信，玩着玩那的一天很快就过去了。老师催的时候带着一种负罪感赶紧看文献，过一段时间后“不想写”的情绪让你总能从论文中抽身出来，继续开始“刷微博刷抖音”的恶性循环。缺失方法。不知道从哪开始，不知道该怎么写。定力不足。写论文需要的时候过长，经常会因为各种原因放弃这件难的事。完美主义作祟。认真的人都苛求完美，要么不做要么就要做到最好，故此迟迟没法完成。
什么题目啊
学院负责毕业生工作的老师应该有修改的权限
OK 需要的话我帮你。
就要看您学校是否有自建库了，一般和知网合作的高校会收录评定为优秀的研究生论文。当然就算查重后也没那么快被学校自建库收录的，系统有很大可能检测不出。不过您抄的段落，您同学是否又借鉴别处呢，建议一定要提前查重下，做到心中有数。早检测知网VIP和PMLC是都有的，或许可以看看。如果毕业查重并没有查出，抄袭的字数太多，日后被发现也是不利的。
请问这个有影响吗？我的是少打了一个字
据学术堂了解，论文题目变更的原因主要为以下几点： 1、因为实际的工作和实习的实践内容发生了变动 2、因为研究需要，需要将题目界定更加严谨。 3、因为经过一段时间的准备，发觉原定的论文题目太大，范围太宽，涉及面过广，来不及进行全面的深入研究。
一、 文献综述 文献综述是研究者在其提前阅读过某一主题的文献后，经过理解、整理、融会贯通，综合分析和评价而组成的一种不同于研究论文的文体。综述的目的是反映某一课题的新水平、新动态、新技术和新发现。从其历史到现状，存在问题以及发展趋势等，都要进行全面的介绍和评论。在此基础上提出自己的见解，预测技术的发展趋势，为选题和开题奠定良好的基础。 二、文献综述的格式 文献综述的格式与一般研究性论文的格式有所不同。这是因为研究性的论文注重研究的方法和结果，而文献综述介绍与主题有关的详细资料、动态、进展、展望以及对以上方面的评述。因此文献综述的格式相对多样，但总的来说，一般都包含以下四部分：即前言、主题、总结和参考文献。撰写文献综述时可按这四部分拟写提纲，再根据提纲进行撰写工作。 前言部分，主要是说明写作的目的，介绍有关的概念及定义以及综述的范围，扼要说明有关主题的现状或争论焦点，使读者对全文要叙述的问题有一个初步的轮廓。 主题部分，是综述的主体，其写法多样，没有固定的格式。可按年代顺序综述，也可按不同的问题进行综述，还可按不同的观点进行比较综述，不管用那一种格式综述，都要将所搜集到的文献资料归纳、整理及分析比较，阐明有关主题的历史背景、现状和发展方向，以及对这些问题的评述，主题部分应特别注意代表性强、具有科学性和创造性的文献引用和评述。 总结部分，与研究性论文的小结有些类似，将全文主题进行扼要总结，提出自己的见解并对进一步的发展方向做出预测。 参考文献，因为它不仅表示对被引用文献作者的尊重及引用文献的依据，而且也为评审者审查提供查找线索。参考文献的编排应条目清楚，查找方便，内容准确无误。关于参考文献的使用方法，录著项目及格式与研究论文相同，不再重复。
论文投稿时一般要求附带一篇“Cover Letter”，好的“Cover Letter”不仅可以使文章锦上添花，更有可能直接决定论文是否被录用。本人切身体会，以已发表论文为例，现将其写法经验归纳如下：Dear Editor,We would like to submit the enclosed manuscript entitled "论文题目", which we wish to be considered for publication in 期刊名The work described has not been submitted elsewhere for publication, in whole or in part, and all the authors listed have approved the manuscript that is We believe that two aspects of this manuscript will make it interesting to general readers of First, 论文亮点Second, 论文亮点Thank you very much for your time and Sincerely yours,作者名注意点：论文亮点一定要简洁明了，一定要有创新，突出你的文章与其它已发表论文的区别。这是 Cover Letter 的主要内容。
1、 什么是cover letter？指的是投稿信2、cover letter的内容主要包括那些？应该简述所投稿件的核心内容、主要发现和意义，拟投期刊，对稿件处理有无特殊要求等（如“not to review” list）。另外，请附上主要作者的中文姓名、通讯地址、电话、传真和e-mail地址。此外有的杂志要求推荐几位审稿人及其联系方式。以及谁已经阅读过该文（当然是牛人）。我投的那个杂志是要求说明你论文研究的意义，以及与这个杂志的相关性，另外还有的可能要写明你没有一搞多投等。此外临床实验要求写明符合伦理学要求。3、 如何写cover letter？各个杂志的具体要求是不一样的，在杂志的guide for authors一般会有要求。如果没有具体的要求，大家可按照通用要求处理。4、常用模板：（1）Cover letterDear M ** The work described has not been submitted elsewhere for publication, in whole or in part, and all the authors listed have approved

Channels in Midbrain Dopaminergic Neurons", which we wish to be considered for publication in Nature NGDNF has long been thought to be a potent neurotrophic factor for the survival of midbrain dopaminergic neurons, which are degenerated in Parkinson’s In this paper, we report an unexpected, acute effect of GDNF on A-type potassium channels, leading to a potentiation of neuronal excitability, in the dopaminergic neurons in culture as well as in adult brain Further, we show that GDNF regulates the K+ channels through a mechanism that involves activation of MAP Thus, this study has revealed, for the first time, an acute modulation of ion channels by GDNF Our findings challenge the classic view of GDNF as a long-term survival factor for midbrain dopaminergic neurons, and suggest that the normal function of GDNF is to regulate neuronal excitability, and consequently dopamine These results may also have implications in the treatment of Parkinson’s Due to a direct competition and conflict of interest, we request that D XXX of Harvard U, and YY of Yale U not be considered as With thanks for your consideration, I amSincerely yours,（四）Dear **We would like to

by the phase speed of a Rossby mode According to the analysis result for the barotropic component of the atmosphere, we obtain a characteristic energy spectrum with distinct slopes for the turbulence and wave regimes separated by the spherical Rhines In order to explain the observational finding that the energy spectrum is proportional to c^2, we put forward a hypothesis based on the criterion of Rossby wave breaking such that the local meridional gradient of potential vorticity becomes negative, dq/dy < 0, somewhere in the With a constant m describing a total mass of the atmosphere for unit area, we have shown that the barotropic energy spectrum of the general circulation E can be represented as E=mc^Corresponding Author:D Hiroshi L TanakaDivision of Geoenvironmental SciencesUniversity

一封Cover letter写作要点需要下述内容：论文题目、研究发现概要、投稿动机、原创与作者同意书、推荐审稿人、与期刊编辑有过的互动等。Cover letter 是写给杂志编辑的投稿信，一封成功的Cover letter，能够快速吸引期刊审稿人的注意力，让他们在第一时间轻松地理解研究意图和结果，从而有更大机会让其愿意深入阅读研究成果，同时也会显著提高论文被接收的几率。样稿：Dear D White，亲爱的怀特先生：We wish to submit our article “Impact of season on disease Z” to be considered for publication in the Journal of Chronic Disease Treatment as a Short C我们想要将我们的文章：疾病Z的季节影响，作为短篇交流发表在慢性病治疗杂志上。In our previous research (Black et , J Sci Res 2014;21:1-10) we found that treatment X was more effective than treatment Y in reducing chronic disease Z However, we noticed that the improvement for both treatments was much greater (>10%) in winter than in the summer In order to explore this unexpected finding, we carried out further research, presented in this 我们前期的研究发现X治疗方法在减少疾病Z发病上比Y治疗方法更有效。但是，我们发现冬季两种治疗方法比夏季的治疗效果都有提高（大于10%）。为了探索这个发现，我们进行了更一步的研究，在目前的文章中呈现研究结果。We found that ambient temperature had no effect on reduction of disease Z with either However, detailed analysis of patient behavior revealed that patients were more likely to be absent from home in the summer months, and so more likely to miss their medication 我们发现气温对疾病Z的治疗没有影响。然而，更细致的分析发现，病人们在夏季更倾向于不在家，因此会忘记治疗。 After implementing a dosing strategy to minimize this effect, no significant difference between summer and winter could be detected with either 在分析剂量效果以减少误差，发现冬季和夏季的治疗差别并没有意义。We think this article will be of interest to your readers as it demonstrates increased treatment effectiveness without increasing overall It also reveals some interesting aspects of patient behavior, an area of study which has received increasing attention in the field of chronic disease treatment over the past 我们认为这篇文章会让你们的读者感兴趣，研究发现了在不增加治疗剂量时的治疗有效性，病人的行为对治疗的影响等需要受到进一步关注的领域。We suggest the following reviewers for this article:Andrew Adams (adams@univ-)Billy Bloggs ()Caroline Carter (dr_uk)我们建议以下专家进行审稿。I am authorized on behalf of all the authors of this article to confirm that no author has any conflict of interest to disclose, all authors have approved the version submitted for publication, the work in this article is original and has not been published previously,and the article is not under consideration by any other 我代表这篇文章的作者进行声明，作者之间无利益冲突，同意发表该文章，该研究属于原创，之前没有发表，也没有投稿到其他杂志。We thank you for your kind consideration of our Please do not hesitate to contact me directly if any further information is I look forward to hearing from 我们感谢您对这篇文章的关注。如果有问题请及时与我联系。我期待您的回信。1、论文题目必须保证投信里面的文章标题和投稿系统里面的保持一致。2、研究发现概要用3到4句话叙述研究最重要的发现，避免使用技术或专业术语。这部分的主要目标是在既有的文献背景下构建研究发现。3、投稿动机向期刊编辑说明为何这个研究适合发表在该期刊上，何处与期刊目标相符，等。4、原创与作者同意书在投稿信的最后，必须声明论文没有在其他期刊等待发表，所有作者皆阅读过全文并同意投稿期刊。除了以上必要信息，有写期刊会要求其他信息，帮助期刊编辑审核，作者要注意期刊的相关规定。5、推荐审稿人大部分的期刊都会鼓励作者推荐审稿人，甚至是不希望由谁来担任审稿人，这个动作有助于编辑加速审稿流程。作者应谨慎推荐审稿人，审稿人与作者不该有任何利益冲突，能够公正评审论文，提供有价值的评论。有利益冲突的人员，便可列进不属意的审稿人名单中。6、与期刊编辑有过的互动如果作者在投稿前与期刊编辑有过互动，可能是社交网路或是会议，如果编辑曾经表示过对你的研究感兴趣，记得在投稿信中提及。扩展资料：cover letter的写作技巧：1、主编的姓名一定要拼写正确：首先，必须保证正确的称呼。如果能找到期刊主编的姓名，在coverletter的开头就称呼主编的姓，而不是全名。例如，可以称呼她为”Dear D White” 而不是“Dear D Jane White”。如果不确定主编的姓名，就可以直接称呼为“Dear Editor”或“Dear Editor-in-Chief”。2、文章标题：必须保证投信里面的文章标题和投稿系统里面的保持一致。如果您更改了文章，也需要更改投稿信。3、期刊名称: 必须保证把期刊名称拼写正确。如果文章之前被拒稿过，现在重新投稿，一定要记住把投稿信里面的期刊名称改掉。4、文章类型: 标明文章类型（研究性文章， 综述还是短篇通讯等），并且确认和投稿系统里保持一致。5、简洁：不要大段的重复文章里面的东西。6、准确:一定不能有拼写错误，再次确认保证投稿信是100%正确。投稿信里面的数据和文章正文的数据一致。
