科学论文的组织通常遵循标准化的模式，即众所周知的IMRAD结构(导言、方法、结果和讨论)。本文以发表在PLoS系列期刊上的4.5万篇论文全文为研究对象，从文献计量学的角度，研究了科技论文的引文分布以及被引文献的年代。一旦文章的部分被重新排列成遵循IMRAD顺序，所有PLoS期刊上被引用的参考文献在文章正文中的位置是不变的，大部分参考文献都是在引言和讨论中占据的。它还提供了被引用文献的年代因章节不同而不同的证据，在方法中找到了较早的参考文献，在讨论中找到了较新的参考文献。这些结果提供了对引文在学术交流过程中的不同作用的洞察。
The organization of scientific papers typically follows a standardized pattern, the well-known IMRaD structure (introduction, methods, results, and discussion). Using the full text of 45,000 papers published in the PLoS series of journals as a case study, this paper investigates, from the viewpoint of bibliometrics, how references are distributed along the structure of scientific papers as well as the age of these cited references. Once the sections of articles are realigned to follow the IMRaD sequence, the position of cited references along the text of articles is invariant across all PLoS journals, with the introduction and discussion accounting for most of the references. It also provides evidence that the age of cited references varies by section, with older references being found in the methods and more recent references in the discussion. These results provide insight into the different roles citations have in the scholarly communication process.
