英文摘要的修辞
(1)摘要中的第一句话不要与文题重复,要有所变化,补充一些细节。如文题为:Expression of RACK1 in primary colon cancers.则摘要第一句话不要写为To detect the expression of RACK1 in primary colon cancers.最好改为To detect RACK1 gene over-expressed in primary colon carcinoma by in situ hybridisation.(2)可用动词的情况应尽量避免应用动词的名词形式。如: 应当用Her-2 oncogene
amplification in prostate cancer was measured.而不用Measurement of Her-2 oncogene amplification in prostate cancer was made.(3)正确使用冠词,包括定冠词the和不定冠词a或 an;区分可数名词和不可数名词是关键。如expression做(基因)表达用时为不可数名词,不能加“s”.对可数名词尽可能使用其复数形式。
(4)应当用预置短语分开或用连字符断开名词词组,避免使用连续多个形容词或名词来修饰名词。如用sections of formalin-fixed and paraffin-embedded tissues, 而不用formalin fixed and paraffin embedded tissue sections。
(5)注意平行结构:在表述各相同的并列成分时,不论是词类、词组、从句或分句,每个成分都必须对等。如The purpose of this study was to analyze the new proposed classification and determining which classification was clinically useful.其中第二个表语是动名词短语,与第一个表语不定式短语不一致,不符合平行结构原则。
(6)比较必须在同类的事物之间进行,切忌对不同类型事物进行比较。例如:The survival of patients with MSI+ phenotype was better than MSI-phenotype.此句比较对象不对等,应改为The survival of patients with MSI+ phenotype was better than that of patients with MSI-phenotype.英文摘要的文体
(1)要客观地叙述方法和结果, 用词要质朴无华, 避免使用带感情色彩或广告式宣传的词语。不宜写类似下列的句子:A very interesting example is found that „;The staining yields excellent results;The method is very useful for „.(2)使用正式文体, 不用口语体和非规范缩写词。如isn’t, aren’t, hadn’t, hadn’t, haven’t, don’t, can’t, wouldn’t, a lot of, a bit, too(also), thru(through), exam(examination), lab(laboratory)等。
(3)造句时尽量使动词靠近主语。如:用Our results are in contradiction with these observations because 53% of our MFH-like PLPs and 10% of epithelioid PLPs were immunoreactive for CD34.而不用Our results that 53% of MFH-like PLPs and 10% of epithelioid PLPs were immunoreactive for CD34, are in contradiction with these
observations.(4)尽量应用重要事实开头,避免短语或从句开头。如MCMV tended to infect GFAP-positive glial cells in the periventricular area during acute infection in the present study.而不用In the present study, during acute infection, MCMV tended to infect GFAP-positive glial cells in the periventricular area.(5)摘要只限表示新消息、新内容,应减少或取消对过去研究情况的描述,减少或取消不必要的背景信息。摘要也不应包括作者对未来的计划,如“有关XXX方面的研究有待于进一步开展”等。
(6)省略。为避免重复和缩小摘要的篇幅,科技英语多采用省略的写法。在并列复合句里,后面分句如与前面分句相同的部分,往往可以省略。常见的是谓语动词省略,在省略处可用或不用逗号分开。如,Despite vaccination, one patient developed pneumococcal menigitis and another, pneumococcal bacteremia.此外,用when, while, if, as, though(although)和whether 等连词连接的时间、条件、方式、让步等从句,如其谓语中有be,而且其主语与主句的主语相同或为it时,从句的主语和be也可以省略。
(7)避免使用“悬垂分词”(hanging participle).使用没有逻辑主语的分词短语做状语,是一种最常见的修辞错误,例如: Following his advice, the bacteria were stained with thionin.应写为Following his advice, we stained the bacteria with thionin.或In accordance with his advice the bacteria were stained with thionin.(8)避免是一些含义模糊的形容词或副词。如: considerable, appreciable, substantial, very, relatively, comparatively, essentially, duly, somewhat, rather, necessarily, inevitably 等。
(9)删繁就简,应当用合适的短语代替子句,用合适的单词代替短语。如: 用increased 代替has been found to increase, 用was代替was considered to be, 用seemingly代替it would seem that, 等等。
第二篇:英文摘要
谈谈英文摘要的书写技巧
随着科学技术的发展,为满足对外交流的需要,国家统一规定,公开发表的学术论文应附有英文摘要。
英文摘要的内容要求与中文摘要一样,包括目的、方法、结果和结论四部分。但是,英文有其自身特点,最主要的是中译英时往往造成所占篇幅较长,同样内容的一段文字,若用英文来描述,其占用的版面可能比中文多一倍。因此,撰写英文摘要更应注意简洁明了,力争用最短的篇幅提供最主要的信息。第一,对所掌握的资料进行精心筛选,不属于上述“四部分”的内容不必写入摘要。第二,对属于“四部分”的内容,也应适当取舍,做到简明扼要,不能包罗万象。比如“目的”,在多数标题中就已初步阐明,若无更深一层的目的,摘要完全不必重复叙述;再如“方法”,有些在国外可能早已成为常规的方法,在撰写英文摘要时就可仅写出方法名称,而不必一一描述其操作步骤。
中英文摘要的一致性主要是指内容方面的一致性,目前对这个问题的认识存在两个误区,一是认为两个摘要的内容“差不多就行”,因此在英文摘要中随意删去中文摘要的重点内容,或随意增补中文摘要所未提及的内容,这样很容易造成文摘重心转移,甚至偏离主题;二是认为英文摘要是中文摘要的硬性对译,对中文摘要中的每一个字都不敢遗漏,这往往使英文摘要用词累赘、重复,显得拖沓、冗长。英文摘要应严格、全面的表达中文摘要的内容,不能随意增删,但这并不意味着一个字也不能改动,具体撰写方式应遵循英文语法修辞规则,符合英文专业术语规范,并照顾到英文的表达习惯。
选择适当的时态和语态,是使摘要符合英文语法修辞规则的前提。通常情况下,摘要中谓语动词的时态和语态都不是通篇一律的,而应根据具体内容而有所变化,否则容易造成理解上的混乱。但这种变化又并非无章可循,其中存在着如下一些规律:
1、时态:大体可概括为以下几点。
1)叙述研究过程,多采用一般过去时。
2)在采用一般过去时叙述研究过程当中提及在此过程之前发生的事,宜采用过去完成时。
3)说明某课题现已取得的成果,宜采用现在完成时。
4)摘要开头表示本文所“报告”或“描述”的内容,以及摘要结尾表示作者所“认为”的观点和“建议”的做法时,可采用一般现在时。
2、语态:在多数情况下可采用被动语态。但在某些情况下,特别是表达作者或有关专家的观点时,又常用主动语态,其优点是鲜明有力。
掌握一定的遣词造句技巧的目的是便于简单、准确的表达作者的观点,减少读者的误解。
1、用词力求简单,在表达同样意思时,尽量用短词代替长词,以常用词代替生僻词。但是当描述方法、步骤时,应该用狭义词代替广义词。例如,英文中有不少动词,do,run,get,take等,虽简单常用,但其意义少则十几个,多则几十个,用这类词来描述研究过程,读者难免产生误解,甚至会不知所云,这就要求根据具体情况,选择意义相对明确的词,诸如perform,achieve等,以便于读者理解。
2、造句
1)熟悉英文摘要的常用句型:尽管英文的句型种类繁多,丰富多彩,但摘要的常用句型却很有限,而且形成了一定的规律,大体可归纳为
a)表示研究目的,常用在摘要之首In order to……This paper describes…, …The purpose of this study is……
b)表示研究的对象与方法The [curative effect/sensitivity/function] of certain [drug/kit/organ….] was [observed/detected/studied…]
c)表示研究的结果:[The result showed/It proved/The authors found] that……
d)表示结论、观点或建议:The authors [suggest/conclude/consider] that…
2)尽量采用-ing 分词和-ed 分词作定语,少用关系代词 which , who 等引导的定语从句。由于摘要的时态多采用一般过去时,使用关系代词引导的定语从句不但会使句式变的复杂,而且容易造成时态混乱(因为定语和它所修饰的主语、宾语之间有时存在一定的“时间差”,而过去完成时、过去将来时等往往难以准确判定)。采用-ing 分词和-ed 分词作定语,在简化语句的同时,还可以减少时态判定的失误。
以上所述只是撰写英文摘要时应注意的问题中的一小部分,尚有许多问题,需要进一步探讨。总之,英文摘要作为论文的重要组成部分,其修改和完善是永无止境的。
第三篇:摘要英文
摘要
温度是生产过程中常见和重要的物理参数。在日常生活和工业生产中,人们对温度测量的要求越来越高,主要表现在测量的精度、可靠性、稳定性等方面。温度的测量直接关系到产品的质量、生产效率以及生产安全等重大技术指标。同时,测温系统的成本和便携性也越来越受到人们的关注。传统的温度测量系统中,温度测量环节是由模拟温度传感器加上高性能的运放和A/D转换器构成,然后通过单片机进行控制,因而,所需的外围器件较多,硬件成本开销很大。基于片上可编程系统PSoC因在其芯片内部集成了丰富的模拟和数字模块,使一系列的控制任务大部分都可以在芯片内部完成,而且其可动态编程配置的功能,使其具有很高的灵活性,使得控制方便且生产成本比较低,所以在工业生产控制中得到了广泛的应用。本文设计了一种以Pt1000作为温度传感器,以可编程片上系统PSoC作为核心芯片,采用片内的模拟和数字IP核资源,利用Modbus协议进行上位机通信的温度测量系统。系统拟采用公司自主研发的温度采集器,集成为高密度温度采集系统,是针对高密度、高精度的监控,以及对于存在众多热电阻的场合设计的温度测量系统。
本文首先介绍了课题研究的背景和意义,并分析了当前温度测量技术和可编程片上系统PSoC的研究现状。以可编程片上系统芯片CY8C5868AXI-LP032作为系统核心,设计了硬件电路整体结构,系统分为四个子模块,温度采集模块、放大模块、A/D转换模块、通信模块。选取铂电阻Pt1000作为温度传感器,铂电阻采用三线制接法。温度信号输入电路采用独特的电桥电路测量技术,具有没有引线电阻影响,抗干扰能力强,电桥电路与测量电路完全隔离等优点。电桥电路中输出的模拟电压经过放大后,输入至AD转换器中变为数字信号,再由处理器换算出相应温度,在硬件电路设计中对各部分子电路进行了原理和功能的介绍,其中在对Δ-ΣADC配置时,根据系统要求对其分辨率、采样率进行相关参数配置。在系统硬件设计平台的基础上,使用PSoC Creator2.0集成开发环境进行了系统软件的设计,其中包括温度信号采集、AD值与温度值的转换、温度补偿、Modbus通信协议和信息帧格式等。设计中主要针对的是实际温度值获取、温度误差补偿的设计,其中采用的主要方法是分段线性化和线性标度变换相结合的方
法。为满足PSoC与计算机的通信加入了基于Modbus的通信协议,采用RS485接口标准来完成两者之间的数据发送和接收,在PSoC内部配置了全双工通信UART的各个参数,采用CRC循环冗余的校验方式。最后对系统进行调试,以测试工程的运行情况,首先使用PSoC的专用下载工具PSoC MiniProg对系统进行下载烧写接口调试,通过Visual Basic进行通信测试,然后通过电阻箱模拟铂电阻温度测试。最后对本文的的工作进行了总结,同时对其作出进一步展望。

3.文摘中的特殊字符
特殊字符主要指各种数学符号、上下脚标及希腊字母,它们无法直接输入计算机,因此都需转成键盘上有的字母和符号。
Ei对此有专门规定。希望在文摘中尽量少用特殊字符及由特殊字符组成的数学表达式。因为它们的输入极为麻烦,而且极易出错,影响文摘本身的准确性和可读性,应尽量不用,改用文字表达或文字叙述.更复杂的表达式几乎难以输入, 应设法取消。
4.缩写字及首字母缩写词(Abbreviations and Acronyms)
对那些已经为大众所熟悉的缩写词,如radar、laser、CAD等,可以直接使用。对于那些仅为同行所熟悉的缩略语,应在题目、文摘或键词中至少出现一次全称。
