一、当文内引用采用姓名和年份的方式，则以时间顺序在文内列出多个文献，再以字母顺序在文后列出这些文献。
当文内引用采用文献号，则以数字顺序在文内和文后列出文献。
二、不同的期刊因其风格差异可能有不同的引用规则。
例如，目标期刊采用APA格式，"et al."只在文章有六个或六个以上作者时才在文内使用。因此，一定要仔细查看目标期刊的作者须知和已发表的论文。
三、如果在文内引用会议摘要、会议论文集、个人通信或未发表的数据，应当以括号注明出版状态。
四、文献可以各种方式置于文中，但是必须具体有意义。
大体来说，根据想强调的内容，文献可在引用的内容或作者姓名之后出现。例如：
1）Starfishfertilization is species specific (17).
2）Peterson (17) reported that starfishfertilization is species specific.
五、不要将文献放置在某项内容的中间或某项研究的概括信息之后。
例如：In a current study (16), proteins expressed by the Epstein-Barr virus have beenclassified into three general groups according to their kinetics and synthesisrequirements.
应修改为：In a current study, proteins expressed bythe Epstein-Barr virus have been classified into three general groups accordingto their kinetics and synthesis requirements (16).
六、文献并不一定要放置在句尾。为区分作者的研究和他人的研究，应将文献放在相应的研究成果后面，而不是整个研究后面。
例如：The Mo+PyF101 M-MuLV used in this study was obtained from the supernatantof the 25-3 cell line confluently infected with the virus (3).
应修改为：TheMo+PyF101 M-MuLY(3) used in this study was obtained from the supernatantof the 25-3 cell line confluently infected with the virus.
七、此外，一个句子中不同内容点的文献需要放在适当的位置，而不是将所有文献一同放在句尾。
例如：Two methods of tailoring the adhesion properties of thermoset stamps exist:One approach is plasma-deposited fluorinated film and coating with aself-assembled monolayer (SAM) offluoroalkyltrichlorosilane; the otherapproach is using C4F8 as a feed gas to deposit Teflon-like antisticking layerand form the SAM layer from the gas phase (3, 4).
应修改为：Two methods oftailoring the adhesion properties ofthermoset stamps exist: One approach isplasma-deposited fluorinated film and coating with a self-assembled monolayer(SAM) offluoroalkyltrichlorosilane(3); the other approach is using C4F8 as afeed gas to deposit Teflon-like antisticking layers and form the SAM layer fromthe gas phase (4).
