Abstract：
This pilot study aims to investigate the differences between varying lengths of bundles in structure and function by comparing the 100 most frequent three-, four-, and five-word bundles in a self-built corpus of dissertations which contains about 3.5 million words. The findings reveal considerable variances between bundles of different lengths in terms of both structure and function. In general, the variances between three-and four-word bundles are greater than those between four-and five-word bundles, and three-and five-word bundles. Structurally, three-and four-word bundles differ significantly in all six main categories. Four-and five-word bundles vary in five categories, while three-and five-word bundles are only different in four categories. Functionally, noticeable variances were observed in research-, text- and participant-oriented bundles between three-and four-word bundles, and three-and five-word bundles. However, four-and five-word bundles only differ significantly in text- and participant-oriented bundles. Interestingly, bundles of varying lengths also vary in patterns that are used to perform the same functions. The results of this study might inform researchers that they need to take bundle lengths into consideration when making generalizations of their findings or comparing bundles between various studies.
摘要：
这项初步研究旨在通过比较100个最常见的三个，来研究不同长度的束在结构和功能上的差异。four-,以及自建的论文语料库中的五个单词束，其中包含约350万个单词。研究结果表明，在结构和功能方面，不同长度的束之间存在相当大的差异。总的来说,三个和四个单词束之间的方差大于四个和五个单词束之间的方差，和三个和五个单词的捆绑。在结构上,三个单词和四个单词束在所有六个主要类别中都存在显着差异。四个和五个单词的捆绑在五个类别中有所不同，而三个单词和五个单词的束只有四个类别不同。功能上,在研究中观察到明显的差异-，文本和面向参与者的三个和四个单词束之间的束，和三个和五个单词的捆绑。然而,四个单词和五个单词的bundle仅在面向文本和面向参与者的bundle中存在显着差异。有趣的是,不同长度的束在用于执行相同功能的模式中也有所不同。这项研究的结果可能会告诉研究人员，他们需要考虑束的长度时，他们的发现进行概括或比较各种研究之间的束。
