【正文】
子上下要有連貫,不能讓句子之間獨(dú)立常見的連接詞語有, However, also, in addition,consequently, afterwards, moreover, Furthermore,further, although, unlike, in contrast, Similarly, Unfortunately, alternatively, parallel results, In order to, despite, For example, Compared with other results, thus, therefore...用好這些連接詞,能夠使觀點(diǎn)表達(dá)得有層次,更加明確。二、 段落的整體邏輯經(jīng)常我們要敘述一個(gè)問題的幾個(gè)方面。首先第一段要明確告訴讀者你要討論幾個(gè)部份...Therefore, there are three aspects of this problem have to be addressed.The first questuon involves...The second problem relates toThe thrid aspect deals with...上面的例子可以清晰地把觀點(diǎn)逐層敘述。三、討論部份的整體結(jié)構(gòu)小標(biāo)題是比較好的方法,把要討論的問題分為幾個(gè)片段。補(bǔ)充說明的部份可以放在最后一個(gè)片段。文章除了本專業(yè)的專業(yè)人士讀懂以外,一定要想辦法能讓更多的外專業(yè)人讀懂。這樣專業(yè)外的人士可以只了解文章的主要觀點(diǎn),而把比較專業(yè)的討論當(dāng)成黑箱子,而這一部份本專業(yè)人士可以進(jìn)一步研究。注意:為了使文章清楚,第一次提出概念時(shí),最好加以個(gè)括弧,給出較為詳細(xì)的解釋。一、英文文摘題目(Title) 即原始文獻(xiàn)的題目,力求簡單明了直接反應(yīng)文獻(xiàn)的主題。 3 文獻(xiàn)的主副標(biāo)題(題目)必須用句號(hào)分開, 不得用分號(hào)或破折號(hào)。 5 特殊字符即數(shù)學(xué)符號(hào)和希臘字母在題目中盡量不用或少用。1 基本特性 (獨(dú)立短文:獨(dú)立性)文摘敘述要簡明,邏輯性強(qiáng)句子結(jié)構(gòu)嚴(yán)謹(jǐn)完整,盡量用短句子EI的文摘長度一般不超過150 words,或1500字母。2 時(shí)態(tài)以一般現(xiàn)在時(shí)為主,也使用一般過去時(shí)和現(xiàn)在完成時(shí)。3 語態(tài)目前,英文摘要仍以被動(dòng)語態(tài)具多,主動(dòng)語態(tài)也偶有出現(xiàn),并有增長的趨勢(shì)。例如:The crystallized samples had been polished before they were etched in a % HF solution at a temperature of 25℃ for 2 s .4 語法修辭(1) 力求簡捷:at a temperature of 250℃ to 300℃ → at 250 to 300℃ at a high pressure of 2 kPa → at 2 kPahas been found to increase → increasedfrom the experimental results, it can be concluded that → the results show注意冠詞用法,分清 a 是泛指,the 是專指; 如 Pressure is a function of temperature 而不應(yīng)是 Pressure is a function of the temperature. (2) 能用名詞作定語的不用動(dòng)名詞作定語,那用形容詞作定語的不用名詞作定語measuring accuracy →measurement accuracyexperiment results →experimental results (3) 可直接用名詞或名詞短語作定語的情況下,要少用of句型accuracy of measurement → measurement accuracystructure of crystal → crystal structure(4) 可用動(dòng)詞的情況盡量避免用動(dòng)詞的名詞形式Measurement of thickness of plastic sheet was made →Thickness of plastic sheet was measured(5)一個(gè)名詞不宜用多個(gè)前置形容詞來修飾,可改用復(fù)合詞,兼用后置定語,如:thermal oxidation apparent activation energy →apparent active energy of thermooxidation或者用預(yù)置短語或連字符( hyphen)斷開名詞組,作為單個(gè)形容詞(一個(gè)形容詞)。 如: From data obtained experimentally, power consumption of telephone switching systems was determined. → Power consumption of telephone suitching systems was determined from data obtained experimentally. 5 一個(gè)典型示例A detailed study of the melting behavior of oriented isotactic polypropylene has been carried out using differential scanning calorimetry. The orientation in isotactic polypropylene was produced by extruding it in solid phase. At extrusion ratio (ER ) greater four, two melting peaks were
