摘要在sci論文中占有重要的地位,一般摘要字?jǐn)?shù)為150-400個(gè)英文單詞,但是很多作者對(duì)sci論文摘要寫作模板并不了解,為此月期刊的小編也結(jié)合以往的經(jīng)驗(yàn),并且和以往評(píng)職人員溝通,在這里給大家講解sci論文摘要寫作技巧,并且也分享了一些sci論文摘要模板范例,大家可以作為參考,有不明白的也可以隨時(shí)與該站的老師進(jìn)行溝通,他們的經(jīng)驗(yàn)豐富,也可以為您提供更多的指導(dǎo)。

sci論文摘要主要包含四個(gè)部分:
1.目的(Objective):直接了當(dāng)?shù)販?zhǔn)確說(shuō)明研究目的或所闡述的問題。如題目已清楚表明,則摘要中可以不重復(fù)。也可以在摘要開始,簡(jiǎn)要說(shuō)明提出問題的背景。英文常以動(dòng)詞不定式“To+動(dòng)詞原形”開頭。
2.方法(Methods):對(duì)研究的基本設(shè)計(jì)加以描述。包括診斷標(biāo)準(zhǔn)、分組情況及隨訪時(shí)間;研究對(duì)象的數(shù)量及特征,以及對(duì)在研究中因副作用或其它原因而撤消的研究對(duì)象數(shù)目;觀察的主要變量及主要的研究方法;治療手段包括使用方法及作用時(shí)間等。若為臨床研究,需說(shuō)明是前瞻性隨機(jī)對(duì)比研究或回顧性分析。方法學(xué)研究要說(shuō)明新的或改進(jìn)的方法、設(shè)備、材料,以及被研究的對(duì)象(動(dòng)物或人)。英文常需要用完整的被動(dòng)或主動(dòng)結(jié)構(gòu)句子,動(dòng)詞用過(guò)去時(shí)態(tài)。
3.結(jié)果(Results):為摘要的重點(diǎn)部分。提供研究所得出的主要結(jié)果,列出重要數(shù)據(jù)。指出新方法與經(jīng)典方法比較而表現(xiàn)出的優(yōu)缺點(diǎn),并說(shuō)明其可信度及準(zhǔn)確性的統(tǒng)計(jì)學(xué)程度。英文要用完整句子,謂語(yǔ)動(dòng)詞用過(guò)去時(shí)態(tài),研究所得數(shù)據(jù)如百分?jǐn)?shù)、血壓等數(shù)字采用臨床病例書寫形式,不必用書面英文表達(dá)。
4.結(jié)論(Conclusion):把研究的主要結(jié)論性觀點(diǎn),用一、二句話簡(jiǎn)明表達(dá),不必另分段落或設(shè)小標(biāo)題。結(jié)論應(yīng)該有直接依據(jù)'避免推測(cè)和過(guò)于籠統(tǒng)。英文用完整句子表達(dá),動(dòng)詞時(shí)態(tài)用一般現(xiàn)在時(shí)或現(xiàn)在完成時(shí)。最好直接寫結(jié)論'也可用一些句型引出結(jié)論。
sci論文摘要模板范例參考:
例1. Hutchings et al. Science 2018 358, 223-227
Abstract:
(1)The selective oxidation of methane, the primary component of natural gas, remains an important challenge in catalysis. (2)We used colloidal gold-palladium nanoparticles, rather than the same nanoparticles supported on titanium oxide, to oxidize methane to methanol with high selectivity (92%) in aqueous solution at mild temperatures. (3)Then, using isotopically labeled oxygen (O2) as an oxidant in the presence of hydrogen peroxide (H2O2), we demonstrated that the resulting methanol incorporated a substantial fraction (70%) of gas-phase O2. (4)More oxygenated products were formed than the amount of H2O2 consumed, suggesting that the controlled breakdown of H2O2 activates methane, which subsequently incorporates molecular oxygen through a radical process. (5)If a source of methyl radicals can be established, then the selective oxidation of methane to methanol using molecular oxygen is possible.
例2. Liu et al. Science 2018, 362, 1276-1281
Abstract:
(1)Achieving high catalytic performance with the lowest possible amount of platinum is critical for fuel cell cost reduction. (2)Here we describe a method of preparing highly active yet stable electrocatalysts containing ultralow-loading platinum content by using cobalt or bimetallic cobalt and zinc zeolitic imidazolate frameworks as precursors. (3)Synergistic catalysis between strained platinum-cobalt core-shell nanoparticles over a platinum-group metal (PGM)–free catalytic substrate led to excellent fuel cell performance under 1 atmosphere of O2 or air at both high-voltage and high-current domains.(4)Two catalysts achieved oxygen reduction reaction (ORR) mass activities of 1.08 amperes per milligram of platinum (A mgPt−1) and 1.77 A mgPt−1 and retained 64% and 15% of initial values after 30,000 voltage cycles in a fuel cell.(5)Computational modeling reveals that the interaction between platinum-cobalt nanoparticles and PGM-free sites improves ORR activity and durability.
以上就是月期刊小編介紹的sci論文摘要寫作技巧,及相關(guān)的摘要模板范例,如果有不明白的可以隨時(shí)與該站的老師進(jìn)行溝通,他們的經(jīng)驗(yàn)是比較豐富的,可以為您的摘要寫作提供指導(dǎo),也可以為您修改潤(rùn)色論文,并且推薦到合適的期刊上,這樣也不會(huì)耽誤論文的發(fā)表。
相關(guān)知識(shí)閱讀:sci論文摘要不能超過(guò)多少字
估計(jì)發(fā)表過(guò)sci論文的會(huì)發(fā)現(xiàn)sci摘要的重要性,其實(shí)很多正規(guī)的sci期刊對(duì)于字?jǐn)?shù)的要求也有很多限制,sci論文摘要也有明確的字?jǐn)?shù)要求,期刊不同要求的字?jǐn)?shù)也不相同,接下來(lái)小編匯總sci摘要功能與分類。
