“避雷”与“排雷”是近年来活跃于网络社交平台的高频流行语，两者均由军事术语通过概念隐喻泛化至日常生活领域，在语义泛化路径、认知动因与语用策略上既具有相似性，又有显著差异。本研究以概念隐喻理论为核心，结合语义泛化理论，选用微博、小红书、豆瓣等平台的语料，对比分析“避雷”与“排雷”的语义泛化现象。本研究发现：其一，两者共享“风险是雷”这一上位隐喻，均以军事域中“雷”的隐蔽性、破坏性、突发性为映射起点，向消费购物、影视娱乐、职场人际等目标域实现跨域映射。其二，泛化路径存在差异，“避雷”侧重事前预警；“排雷”侧重事后揭露。其三，认知动因不同，“避雷”受损失厌恶心理驱动，“排雷”源于掌控渴望与利他分享动机，两者形成语义互补，共同构成当代网民应对风险的双重话语策略。本文拓展了概念隐喻理论在网络流行语对比研究中的应用，揭示了汉语词汇语义泛化的微观认知机制。

"Bilei" and "Pailei" are buzzwords widely circulating on online social platforms in recent years. Derived from military terminology, both have undergone semantic generalization into daily life via conceptual metaphor, bearing similarities as well as marked disparities in their paths of semantic generalization, cognitive motivations and pragmatic strategies. Centered on Conceptual Metaphor Theory and integrated with semantic generalization theory, this research analyzes corpora collected from Weibo, Xiaohongshu, Douban and other platforms to conduct a comparative study on the semantic generalization of "Bilei" and "Pailei". The study yields three major findings: First, the two expressions share the superordinate metaphor RISKS ARE MINES. Taking the concealment, destructiveness and sudden danger of mines in the military domain as the mapping source, they realize cross-domain mappings onto target domains such as consumption, film and television entertainment, workplace and interpersonal communication. Second, they differ in paths of generalization: "Bilei" emphasizes prior warning against hazards, while "Pailei" focuses on exposing hidden pitfalls after they emerge. Third, their cognitive motivations diverge. The use of "Bilei" is driven by loss aversion, whereas "Pailei" stems from people’s desire for control and altruistic sharing motives. Serving as semantic complements to each other, the two terms jointly form a dual discourse strategy for netizens to cope with potential risks. This paper expands the application scope of Conceptual Metaphor Theory in the comparative research of internet buzzwords and reveals the micro cognitive mechanisms behind the semantic generalization of Chinese vocabulary.
