怎样写英文摘要(5篇)

怎样写英文摘要(5篇)

怎样写英文摘要(5篇)第一篇:怎样写英文摘要摘要的类型与基本内容根据内容的不同,摘要可分为以下三大类:报道性摘要、指示性摘要和报道指示性摘要(1)报道性摘要(informative abstract):也常称作信息性摘要或资料性摘要,其特点是全面、简要地概括论文的目的、方法、主要数据和结论。

通常,这种摘要可以部分地取代阅读全文。

(2)指示性摘要(indicative abstract):也常称为说明性摘要、描述性摘要(descriptive abstract)或论点摘要(topic abstract),一般只用二三句话概括论文的主题,而不涉及论据和结论,多用于综述、会议报告等。

该类摘要可用于帮助潜在的读者来决定是否需要阅读全文。

(3)报道-指示性摘要(informative-indicative abstract):以报道性摘要的形式表述一次文献中的信息价值较高的部分,以指示性摘要的形式表述其余部分。

传统的摘要多为一段式,在内容上大致包括引言(Introduction),材料与方法(Materials and Methods),结果(Results)和讨论(Discussion)等主要方面,即IMRAD((Introduction,Methods,Results and Discussion)结构的写作模式。

20世纪80年代中期出现了另一种摘要文体,即“结构式摘要"(structured abstract),该摘要实质上是报道性摘要的结构化表达。

写摘要的注意事项摘要主要讲述本论文的要点。

结论写完以后再写摘要.摘要给人第一口苹果的品尝效果.审稿人一般用15分钟看摘要和引言.如果第一印象不好,他/她会去寻找理由建议主编退稿.5 摘要的读者面比论文全文的读者面大得多。

不要用第一人称。

写摘要的顺序第一句话:讲一下你这篇文章的研究意义(但是有的杂志不需要这句话)第二句话:以 To eluicdatie the mechanism..., To investigate....,或者for the purpose of....开头来讲述你这样研究的目的。

AbstractWith the increasing globalization of academic research, it has become essential for scholars to effectively communicate their work to a wider audience. One crucial element in this process is the abstract, which summarizes the main points and findings of a research paper. In this article, we will provide an example of an English abstract for a research paper, demonstrating key elements and tips for writing an effective abstract.IntroductionThe abstract serves as a brief overview of a research paper, allowing readers to quickly grasp the purpose, methodology, and outcomes of the study. It should be concise yet informative, providing enough information to engage the reader while remaining within a specified word limit.Main BodyI. Purpose and BackgroundThe first element of an abstract is a clear statement of the research paper's purpose and its background. It should outline the rationale for the study, highlighting any research gaps or unanswered questions in the field. For example:This research aims to investigate the effects of climate change on coastal ecosystems, with a focus on marine biodiversity and coral reef health. Given the increasing threats to these ecosystems, understanding the potential impacts of climate change is crucial for effective conservation strategies.II. MethodologyThe abstract should briefly describe the methodology employed in the research. This can include the study design, data collection methods, and analytical approaches. However, detailed technical information should be avoided. For example:A combination of field surveys, laboratory experiments, and statistical analyses were conducted to assess the long-term effects of temperature increase and ocean acidification on coral reefs. Data on species diversity, abundance, and health were collected from various reefs in the Caribbean region.III. ResultsThe abstract should highlight the key findings of the research. It should summarize the outcomes and conclusions derived from the data analysis. However, specific data or numerical results should be avoided, focusing instead on general trends and significant discoveries. For example:Our study revealed a significant decline in coral species diversity and overall health in response to increased water temperatures and ocean acidification. Furthermore, we found a decrease in the abundance of commercially important fish species, indicating potential impacts on local communities dependent on coral reef resources.IV. Implications and ConclusionThe abstract should conclude with a discussion of the broader implications of the research and its significance. It should provide a concise statement summarizing the main contributions of the study to the field and any recommendations for future research or policy implications. For example:These findings highlight the urgent need for immediate actions to mitigate the effects of climate change on coastal ecosystems. Implementing measures to reduce greenhouse gas emissions and establishing marine protected areas can help safeguard marine biodiversity and protect the livelihoods of communities dependent on coral reef resources.ConclusionIn conclusion, writing an effective English abstract is crucial for communicating the key points and contributions of a research paper. By providing a clear purpose, concise methodology, major findings, and broader implications, the abstract serves as a concise summary of the research work, enticing readers to delve deeper into the full paper. By following the guidelines and structure provided in this example abstract, researchers can enhance their chances of effectively conveying their research to a global audience.。

1、现代化要求教师角色重新定位。

The Demand of Relocating Teachers’ Role in ModernizationIn the current era of globalization, the role of teacher in education is undergoing great change. Instead of providing knowledge for students once and for all, teachers are expected to show the students how to find, obtain and use knowledge on their own. More importantly, teachers should act as a facilitator and counselor for students’ future development. To achieve this goal, teachers need to respond to students’ abilities and adapt to the changing demand readily. In brief, teaching is all about offering paths to students and keeping them highly motivated on the way.2、博物馆免费开放:亟待公众热情参与。

The Museum is Free:the Enthusiasm of the Public is ExpectedIn March 2008, our government had made a decision that the museum would be opened free for the public. This decision is welcomed and shortens the distance between the public and the museum, which not only ensures the cultural rights of the public but also promotes economic growth though it still has some disadvantages. Specifically speaking, it provides an opportunity for the public participation and can arouse their enthusiasm. Meantime, the system construction of the public participation should be strengthened thereby to improve the utilization of the publiccultural resources. Moreover, various museum exhibitions can sat isfy the pu blic’s spiritual andcultural needs and cultivate their loyalty and enhance the cohesion of a nation. Besides, it also promotes the local economic development based on the development of cultural heritage.3、论科学研究的方法。

A regional perceptual classifier is employed to assign a noise sensitivity index to each region. The watermark is inserted in the original image according to this index by using block DCT. The detection of the watermark is designed to achieve a desired false alarm probability. Digital watermarking has been proposed as a solution to the problem of copyright protection of multimedia data in a networked environment. It makes possible to tightly associate to a digital document a code allowing the identification of the data creator, owner, authorized consumer, and so on. In this paper a new watermarking algorithm for digital images is presented: the method, which operates in the frequency domain, embeds a pseudo-random sequence of real numbers in a selected set of DCT coefficients. After embedding, the watermark is adapted to the image by exploiting the masking characteristics of the human visual system, thus ensuring the watermark invisibility. By exploiting the statistical properties of the embedded sequence, the mark can be reliably extracted without resorting to the original uncorrupted image. Experimental results demonstrate that the watermark is robust to several signal processing techniques, including JPEG compression, low pass and median filtering, histogram equalization and stretching, dithering, addition of Gaussian noise, resizing, and multiple watermarking.Keyword: Digital watermarking; Copyright protection; Security; Image authentication中文翻译:基于DCT变化域系统的鲁棒性图像水印算法摘要文提出了一个自适应水印技术。

采用区域感知分类器来对每一个区域指定一个噪声敏感系数指标,通过这种基于块的DCT变换的指标来把水印嵌入到原始图像,这种对水印的检测的目的是为了实现一个所需要的错误警戒概率。

数字水印技术作为一种在网络环境中对多媒体数据版权保护问题的解决方法而被提出,它使得紧密联系一段数据文件代码来鉴别数据的创建者、所属者、授权用户等成为了可能。

本文提出了一种新的数字图像水印算法:在频域中,往已选择的DCT系数集合中嵌入一段实数伪随机序列,这样,根据人眼的视觉隐蔽特性而把水印掩藏在图片中,从而保证水印的隐藏。

利用嵌入的随机序列的统计特性很容易的提取出水印,而不用依靠完整的原始图像。

实验表明,这种水印技术对于常见的JPEG压缩、低通和中值滤波、直方图均衡和展缩、抖动、加高斯噪声、尺度变换及多水印等信号处理技术有很好的鲁棒性。

关键字:数字水印;版权保护;安全性;图像认证2、英文原文:TRANSPARENT ROBUST IMAGE WATERMARKING AbstractWe propose a watermarking scheme to hide copyright information in an image. The scheme employs visual masking to guarantee that the embedded watermark is invisible and to maximize the robustness of the hidden data. The watermark is constructed for arbitrary image blocks by filtering a pseudo-noise sequence (author id) with a filter that approximates the frequency masking characteristics of the visual system. The noise-like watermark is statistically invisible to deter unauthorized removal. Experimental results show that the watermark is robust to several distortions including white and colored noises, JPEG coding at different qualities, and cropping.中文翻译:透明鲁棒性图像水印算法摘要我们提出了一个把版权信息隐藏在图像中的水印方案。
