摘要：

目的 基于多模态话语分析理论，探讨我国英文科技期刊在国外社交媒体平台上的传播策略，分析其多模态话语的呈现形式、构建逻辑与传播机制，为我国英文科技期刊的国际传播能力提升提供理论支持与实践参考。 方法 用Python抓取2024年1月1—31日X与Facebook平台点赞量排名前60的帖子，共计120篇，运用内容分析法与多模态话语分析法相结合进行研究。 结果 在图像模态中，论文成果类内容占比最高，形式以“文字＋图片”形式为主；文字模态多为陈述句，使用专业术语，保障学术精准性。 结论 在文化层面，推动“科技-文化”融合，增强视觉传播力；在语境层面，因媒制宜，强化议题响应；在内容层面，构建多模态协同传播矩阵；在表达层面，优化语言系统，打造统一视觉识别体系。

Abstract:

Purposes Based on the theory of multimodal discourse analysis， this study explores the communication strategies of Chinese English-language scientific journals on international social media platforms. It analyzes the presentation forms， construction logic， and dissemination mechanisms of their multimodal discourse， aiming to provide theoretical support and practical reference for enhancing the international communication power of these journals. Methods Using Python， 120 top-liked posts （top 60 each） from X and Facebook during January 1-31， 2024 were collected. Content analysis and multimodal discourse analysis were applied in combination. Findings In the visual modality， research outcome–oriented content accounted for the largest proportion， with the most common format being “text + image”. In the textual modality， declarative sentences and specialized terminology were frequently used to ensure academic precision. Conclusions At the cultural level， it is essential to promote the integration of “technology and culture” to enhance visual communication efficacy. At the contextual level， strategies should be tailored to different media platforms to strengthen issue responsiveness. Regarding content， a multimodal collaborative dissemination matrix should be constructed. In terms of expression， optimizing the linguistic system and establishing a unified visual identity system are crucial.
