摘要： 因外界非体积功参与从而促进反应发生的现象是物理化学研究的重要领域，由此衍生出电化学、光化学等一系列物理化学三级学科。但能够用定量关系式说明非体积功对活化能影响的情况并不多见。近年来，以微滴化学为代表的表面能对化学反应活化能的影响开始引起人们的重视，并提出了多个新概念。本文简要分析了表面能等非体积功促进反应的本质，辨析了其作用方式与催化作用的不同，提出了规范相关概念的建议。相关讨论有助于人们正确认识催化概念和表面能促进反应的本质。

Abstract: The phenomenon of chemical reaction enhancement through exertion of external nonexpansion work constitutes a significant research area in physical chemistry, giving rise to specialized subdisciplines such as electrochemistry and photochemistry. However, quantitative explanations regarding the effect of non-expansion work on activation energy remain limited. Recent studies have drawn increasing attention to surface energy effects on reaction activation energies, particularly in microdroplet chemistry, leading to several novel concepts. This paper systematically examines the fundamental mechanisms of surface energy and other non-expansion work in reaction enhancement, clarifies their distinctions from catalytic processes, and proposes standardized conceptual frameworks. These discussions contribute to correct understanding of catalysis and the nature of surface energy-mediated reaction enhancement.
