下面是好好范文网小编收集整理的写论文的英文 毕业论文：英语论文怎么写，仅供参考，欢迎大家阅读！

对我国青年学者或学生来说，用英语写作的难点不是没有写作材料，不是不熟悉专业词汇，也不是没有打下良好的英语基础。用英语写论文难，是因为不太了解学术英语的语言特点。关于学术英语写作的语言技巧，我们已在第一部分作了较详细的介绍。此部分讨论学术论文写作的方法，包括学术论文写作中常用的句型结构，我们都在此作较详细介绍，以便读者模仿练习，将写作工作化难为易。

一般来说，一篇完整规范的学术论文由以下各部分构成：

Title(标题)

Abstract(摘要)

Keywords(关键词)

Table of contents(目录)

Nomenclature(术语表)

Introduction(引言)

Method(方法)

Results(结果)

Discussion(讨论)

Conclusion(结论)

Acknowledgement(致谢)

Reference(参考文献)

Appendix(附录)

学术论文的正文一般包括Method，Result，Discussion三个部分。这三部分主要描述研究课题的具体内容、方法，研究过程中所使用的设备、仪器、条件，并如实公布有关数据和研究结果等。Conclusion是对全文内容或有关研究课题进行的总体性讨论。它具有严密的科学性和客观性，反映一个研究课题的价值，同时提出以后的研究方向。

英文论文引言的写作技巧

引言的写作技巧

学术论文中的引言(Introduction)是对全文内容和结构的总体勾画。引言尽管不像摘要那样有一定的篇幅限制和相对固定的格式，但在内容和结构模式上也有需要遵循的规律。本章首先介绍这些规律，然后探讨需要掌握的语言技巧。

8.1 引言的内容与结构布局

引言的主要任务是向读者勾勒出全文的基本内容和轮廓。它可以包括以下五项内容中的全部或其中几项：

介绍某研究领域的背景、意义、发展状况、目前的水平等;

对相关领域的文献进行回顾和综述，包括前人的研究成果，已经解决的问题，并适当加以评价或比较；

指出前人尚未解决的问题，留下的技术空白，也可以提出新问题、解决这些新问题的新方法、新思路，从而引出自己研究课题的动机与意义；

说明自己研究课题的目的；

概括论文的主要内容，或勾勒其大体轮廓。

如何合理安排以上这些内容，将它们有条有理地给读者描绘清楚，并非容易之事。经验告诉我们，引言其实是全文最难写的—部分。这是因为作者对有关学科领域的熟悉程度，作者的知识是渊博、还是贫乏，研究的意义何在、价值如何等问题，都在引言的字里行间得以充分体现。

我们可以将引言的内容分为三到四个层次来安排(如图8.1所示)。第一层由研究背景、意义、发展状况等内容组成，其中还包括某一研究领域的文献综述；第二层提出目前尚未解决的问题或急需解决的问题，从而引出自己的研究动机与意义；第三层说明自己研究的具体目的与内容；最后是引言的结尾，可以介绍一下论文的组成部分。

第一层：1) Introducing the general research area including its background, importance, and present level of development……………………………………………………………2) Reviewing previous research in this area……………………………………………………………………第二层： Indicating the problem that has not been solved by previous research, raising a relevant question ……………………………………………………………………………………………………………………………………………………………………………………………第三层：Specifying the purpose of your research………………………………………………………………………………………………………………第四层：1) Announcing your major findings ……………………………………………………………………………………………………………2) Outlining the contents of your paper …………………………………………………………………………………………………………………………………………………………………………………　

图8.1 引言的结构布局之一

值得注意的是，引言中各个层次所占的篇幅可以有很大差别。这一点与摘要大不一样，摘要中的目的、方法、结果、结论四项内容各自所占的篇幅大体比例一样(见7.2节)。而在引言中，第一个层次往往占去大部分篇幅。对研究背景和目前的研究状况进行较为详细的介绍。研究目的可能会比较简短。

引言与摘要还有一点不同的是，摘要中必须把主要研究结果列出，而在引言中(如果摘要与正文一同登出)结果则可以省略不写，这是因为正文中专门有一节写结果(results)，不必在引言中重复。

下面这段引言的例子摘自一篇关于混合电动汽车的研究论文，大部分篇幅介绍研究背景。

A Hybrid Internal Combustion Engine/Battery Electric Passenger Car for Petroleum Displacement I. Forster and J. R. Bumby INTRODUCTION [1] The finite nature of the world's oil resources and the general concern about automobile emissions have prompted the adoption of energy conservation policies and emphasized the need to transfer energy demand from oil to other sources of energy, such as natural gas, coal and nuclear. [2] A transfer of energy from oil to electricity can be achieved to a limited extent in the road trans- port sector by the increased use of electric vehicle. However, such vehicles are limited in range due to the amount Of energy that can he realistically stored on-board the vehicle without affecting payload. As a consequence of this, electric vehicles must he used in situations where daily usage is well defined, for example, in urban delivery duty. Indeed, it has been in such vehicles as the urban milk delivery vehicles that electric traction drives have been traditionally applied with a great deal of success. Currently the demand is for urban electric vehicles to he developed with greater traffic compatibility in terms of speed and range. 分析：第一层(第1—5段)：介绍混合电动汽车的研究背景、意义、目前的发展水平，需要解决的问题等。第1段：指出混合电动汽车的研究背景。世界石油资源的有限性及人们对汽车排放问题的广泛关注使得能源转换问题尤为重要。第2段：使用电动汽车能够从某种程度上实现能源转换。但问题是电动汽车的续驶里程比内燃机车短。所以目前要解决的问题是提高电动汽车的速度和续驶里程。

[3] Although urban delivery vehicle applications will help to reduce the dependence of the road transport sector on petroleum-based fuels, the major part of this market requires vehicles that are not limited in range and have a performance compatible with internal combustion, i.e. engine vehicles. The use of advanced traction battery technology to overcome the range limitation of electric vehicles is one possible solution. However, this would still result in a vehicle limited in range and may in itself create additional problems. For example, due to the much greater on- board stored energy, the charging time required will be greater than at present. [4] The range limitations of the pure electric vehicle can be overcome by using a hybrid i.c. engine/electric drive which incorporates both an i.c. engine and an electric traction system. Al- though such a vehicle can be designed to meet a number of objectives, it has been argued that a vehicle which seeks to remove the range limitation of the electric vehicle while substituting a substantial amount of petroleum fuel by electrical energy is the vehicle most worth pursuing. With the emphasis of the vehicle design on the electric drive train, the intention may be to operate in an all-electric mode under urban conditions and to use the i.c. engine for long-distance motorway driving. The hybrid mode could then he used for extending urban range and/or improving vehicle accelerative performance on accelerator kick-down.[5] The concept of a hybrid electric vehicle capable of substituting petroleum fuel is' not new, 第3段：市场要求电动汽车的续驶里程及工作性能与内燃机汽车媲美，但是，即使先进电池可以提高电动汽车的续驶里程，但还会有一些问题不能解决。 第4段：续驶里程可以通过使用混合电动汽车来提高。混合电动汽车上既装有内燃机，又装有电动驱动系统，在必要时使用其中一种系统。第5段：回顾并评述前人关于混合电动汽车

Bosch and Volkswagen having built vehicles in the 1970s. More recently, the advent of the Electric and Hybrid Vehicle Research, Development and Demonstration Programme in the United States of America initiated the design and construction of a Near Term Hybrid Vehicle (NTHV) with the principal aim of substituting petroleum fuel by ' wall plug' electricity. [6] As part of the NTHV programme, a large number of conceptual studies were conducted but on vehicles aimed at the American passenger car market. In this paper optimization studies were conducted, but now on a vehicle suitable for the European medium-sized passenger car market. Such optimization studies are important as, with two sources of traction power available, the way in which they are controlled, and their relative sizing, is fundamental to the way the vehicle performs.[7] Before examining in detail the optimum control strategy for the drive train, Section 2 defines the hybrid arrangement under study.

摘要的写作技巧

1. 摘要的种类与特点

摘要主要有以下四种。

第二种是学术会议论文摘要。会议论文摘要往往在会议召开之前几个月撰写，目的是交给会议论文评审委员会评阅，从而决定是否能够录用。所以，比第一种略为详细，长度在200—300字之间。会议论文摘要的开头有必要简单介绍一下研究课题的意义、目的、宗旨等。如果在写摘要时，研究工作尚未完成，全部研究结果还未得到，那么，应在方法、目的、宗旨、假设等方面多花笔墨。

第三种为学位论文摘要。学士、硕士和博士论文摘要一般都要求用中、英文两种语言写。学位论文摘要一般在400字左右，根据需要可以分为几个段落。内容一般包括研究背景、意义、主旨和目的；基本理论依据，基本假设；研究方法；研究结果；主要创新点；简短讨论。不同级别的学位论文摘要，要突出不同程度的创新之处，指出有何新的观点、见解或解决问题的新方法。

以上四种摘要具有许多共性。无论哪种摘要，内容一般都包括：

(1)目的(objectives，purposes)：包括研究背景、范围、内容、要解决的问题及解决这一问题的重要性和意义。

(2)方法(methods and materials)：包括材料、手段和过程。

(3)结果与简短讨论(results and discussions)：包括数据与分析。

(4)结论(conclusions)：主要结论，研究的价值和意义等。

无论哪种摘要，语言特点和文体风格也都相同。首先必须符合格式规范。第二，语言必须规范通顺，准确得体，用词要确切、恰如其分，而且要避免非通用的符号、缩略语、生偏词。另外，摘要的语气要客观，不要作出言过其实的结论。

下面从内容、结构布局和语言特点三方面着手，讨论摘要的写作方法和技巧。

2. 摘要的内容与结构

一般来说，摘要必须包括研究目的，研究方法，研究结果，主要结论等内容。也就是说，摘要必须回答“研究什么”、“怎么研究”、“得到了什么结果”、“结果说明了什么”等问题。

2.1 学术期刊论文摘要

这种摘要随同全文一起发表，简短精炼是其主要特点。只需简明扼要地将研究目的、方法、结果和结论分别用1～2句话加以概括即可(如图所示)。至于研究背景或宗旨应在论文的Introduction部分较详细介绍，不必在摘要里介绍。

DOES ALUMINUM ENTER THE LIQUID OONTAINED

IN POP CANS AND ALUMINUM COOKWARE?

Daniel T. Moss

Campbell, 353 North King St., Xenia OH 45385

Objective: 1This investigation was performed to see if the aluminum in pop cans (易拉罐)and aluminum cookware enters the liquid they contain. It was hypothesized that aluminum does enter the liquids in aluminum cans and cookware. Methods and Materials: This experiment was performed by testing seven different types of carbonated beverages and water boiled in aluminum cookware for three hours. Every hour a sample was removed for testing. The cookware consisted of a new and old aluminum pot. The colorimetric method was used to determine the concentration of aluminum. Results: The results showed that aluminum was present in carbonated beverages and in the water boiled in the cookware. Conclusions: It was concluded that aluminum existed in carbonated beverages and substances cooked in aluminum cookware, and that the concentration of aluminum increased with time. (126 words)

FACTORS INVOLVED IN POAG:

CAROTENOID INTAKE, EYE COLOR, ANDGIRTH MEASUREMENTS

C. A. Greenell and D. M. Spillman

Department of Physical Education, Health and Sports Studies,

Phillops Hall, Miami University, Oxford Oh 45056

Objective: This study investigates possible effects of high intake of carotenoids(类胡罗卜素), eye color, and girth measurements(眼睛大小)on primary open angle glaucoma (POAG 青光眼). Methods and Materials: Researchers designed a questionnaire that inquired about diet and family and personal health history. This questionnaire was administered to 250 individuals suffering from glaucoma. Results and Discussion: The dietary data suggested a possible correlation between low habitual intake of vitamin A, E, and C and higher risk of POAG. In addition, the number of persons suffering from POAG with blue eye color was significantly higher than those with brown or green. Finally, a possible association was suggested concerning girth measurements: those persons with proportionately larger than normal girth measurements may be more likely to suffer from POAG.
