论文参考文献要按时间排序吗

论文如何证正确标注参考文献呢

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。

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.

标注注意事项：

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).

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.

按照你文章中引用的顺序排。

一般就是按照文献出现在文章中的先后顺序来，有些单位或者期刊论文要求参考文献在文章中的对应位置上标。
