论文最好能建立在平日比较注意探索的问题的基础上，写论文主要是反映学生对问题的思考， 详细内容请看下文外文期刊论文格式。

为了避免标题太长而使用缩写词。Effect of LATS(=Long-Acting Thyroid Stimula-tor)and LATS Protectoron HTACA(=Human Thy-roid Adeny Cyclase Activity)长效甲状腺刺激素和长效甲状腺刺激素保护物对人体甲状腺甙酸环化酶活性的作用。考虑文章较长,可在统一的标题下,用不同的副标题分成若干相对独立的篇章。例如:Factors Influ-encing one's Ability to Adopt to Chronic Illness影响个人对慢性疾病适应能力的因素(1)CARE保健;(2)TECHNOLOGY技术学;(3)FAMILY RELATION-SHIPS家庭关系;(4)DEVELOPMENTAL LEVEL发展水平(研究标准);(5)CULTURAL VALUESAND BELIEFS文化价值和信仰。

这部分是对整篇文章的高度概括或浓缩,故要简单、明了。常用的词汇和句型有:Somebody studied(examined investigated,determined,found,reported,interviewed,measured,documented,considered,though evaluated,observed,…)。运用这些动词,所采用的时态通常是一般过去时和现在完成时。被动语态也屡见不鲜,常见有:This study was taken to ex-amine… ;Patients with…were followed up for+时间;It is showed that… ;It is concluded that… ;Indicationswere obtained that… ,等。结尾时常用的表达方法有:The results indicate(show,state,suggest,demon-strate,conclude,express…)that… ;These findingshave special importance in showing that… ;The find-ings have general significance in that… ;This possibilityis strengthening by the observation that… ,等等。例:

Enzyme Linkel Immunosorbent Assay(ELISA)isused to the detection for antibody of anti-thy oglobulinin normal human serum,cord serum,and amniotic flu-id.The results demonstrate that it seemed to be an cer-tain rule that the lower appeared in the amniotic fluid,the highest in cord serum.Antibody is decreasing for anormal level with the grown-up age after birth.It isthus concluded that antibody of anti-thyroglobulin wemeasured may play a certain significance in diagnosis ofcretinism by ELISA.作者采用ELISA对正常人的血清、脐带血清和羊水中的抗甲状腺球蛋白抗体进行了测定。其结果有一定规律:抗体在胎生期首先出现,分娩时浓度达高峰,而后随年龄增长逐渐降至正常水平。故测定该抗体对地方克汀病之诊断有一定意义。
