The following are specific Move and Steps of his model.

Besides, Yang & Allison’s model seems to fit best the conclusion section, although it is based on linguistics, it has been widely used in the analysis of moves and steps in different disciplines and has greater reference value ( Adel et al, 2015 ). Moreover, Zhiqing Hu’s model further improved Yang&Allison’s model, and based on that, he established a model for hard disciplines, which is fit for the present aerospace corpus. Therefore, the combination of the two models provides a solid theoretical basis and a high degree of credibility for this research. III. M ethodology a) Research Question This study is a corpus-based move analysis of the aerospace conclusion section of RA by native English writers, by analyzing 50 pieces of conclusions, this research aims to answer the following two questions: 1. What is the distribution of Moves and Steps in aerospace RA’s conclusion section? 2. What rhetorical structure model is suitable for aerospace RA’s conclusion section? b) Corpus Collection The aerospace discipline in this research can be focused on the study of avionics systems, aircraft design, manufacturing, and other aspects related to mathematics, physics, computers, etc. Based on the above aerospace research direction, following the principles of representativeness, authority, and accessibility proposed by Nwogu (1997), a random sample of 50 articles written by native English speakers were selected from the following two high- profile journals: Progress in Aerospace Sciences , Aerospace Science and Technology , the period lasts © 2023 Global Journals Volume XXIII Issue III Version I 17 ( ) Global Journal of Human Social Science - Year 2023 G Move Analysis of Conclusion Section of Aerospace Research Article
