一篇论文可选取3~8个词作为关键词。
关键词或主题词的一般选择方法:
由作者在完成论文写作后,纵观全文,选出能表示论文主要内容的信息或词汇,这些住处或词江,可以从论文标题中去找和选,也可以从论文内容中去找和选。例如,关键词选用了6个,其中前三个就是从论文标题中选出的,而后三个却是从论文内容中选取出来的。
后三个关键词的选取,补充了论文标题所未能表示出的主要内容信息,也提高了所涉及的概念深度。需要选出,与从标题中选出的关键词一道,组成该论文的关键词组。

学术词汇中最常用的词是一致。学术词汇是一种独特的词汇,这种词汇主要出现在各种不同形式不同内容的学术研究类文体中,在其他文体中出现的频率较低,这类词汇是学习研究必不可少的内容。对于英语学术论文,只有有效掌握与之相关的学术词汇才能更好地阅读英语学术论文,研究英语学习论文,我们要分析哪些是经常出现的学术词汇,哪些是较少出现的学术词汇,在学习研究中做到心中有数,才能有效进行学术词汇学习与研究。比如,在英语的学术类文章中经常出现的学术词汇有attribute, capacity, differentiate, explicit等不同词汇,这些词汇在英语学术论文中出现的频率较高

一、时态时态是个比较复杂的问题虽然有一般的规则但往往在实际文章中很难把握总体的规则已在前边讲过需要重申的是在同一段落中要避免时态跳跃详见学术论文的写作最常见的描述一般现象的时态是一般现在时有时也用一般过去时或一般将来时需要注意的语法In recent years作时间状语时通常要用完成时In recent years,Plesch and coworkers have concluded that many so-called cationic polymerizations do not proceed through intermediates of an ionic nature.二、数词数也有其复杂化特别是在学术论文里有是很难顾及数上的逻辑但一般不将逻辑上的问题视为语法错误只须注意在一个句子中的数和谓语动词的统一即可以下是需要注意的语法不规则变化的单复数单数复数criterion criteria依据phenomenon phenomena现象medium media介质radius radii半径index indices指数appendix appendices附录stimulus stimuli刺激basis bases基础2synthesis syntheses合成matrix matrices基体Novel biomaterials with improved,specific biological action are being developed using polymers that are responsive to environmental stimuli.一些数有特殊性的名词data,kinetics通常作复数名词research,work:不可数名词The data in Table1are obtained from the reactions at different temperatures.The kinetics of polymerization within each droplet are the same as those for the corresponding bulk polymerization.Much research has been done to redirect the tropism of retroviruses by engineering the envelope glycoprotein.Most research on poly(ortho esters)has focused on the synthesis of polymers.一些结构的数<;主谓的统一>one of复数名词单数none of复数名词复数none of单数名词/不可数名词单数no复数名词复数no单数名词/不可数名词单数a kind of单数名词单数this/that kind of单数名词单数these kinds of复数名词复数复数名词of this/that kind复数sort与kind类似a type of单数名词单数a series of复数名词复数a class of复数名词复数the number of复数名词单数a number of复数名词复数Ara-C is one of most important antitumor agents,especially used in the treatment of various leukaemias.One of possibilities for enhancing the pharmacological properties is to link it to a carrier.
