In recent years, urban planners and designers are paying greater attention to Outdoor Thermal Comfort (OTC) studies due to the imminent threat of the Urban Heat Island and climate change on human health. Historically, indoor thermal comfort research assumed steady-state conditions, centralizing on the concept of thermal neutrality to determine optimal environmental parameters. Such research pivoted to investigating how non-steady-state, transient environmental conditions influence comfort. Recent studies underscore the usefulness of positive alliesthesia in providing a productive framework for OTC evaluation. In this article we first clarify the concepts related to thermal comfort-related terms, scales, and models in the literature. Then, we propose four research questions that we believe are important for the research of thermal transient sensations. To answer them, we present the state of current research and gaps for the field and provide directions that could advance the knowledge on dynamic OTC.

近年来，由于城市热岛和气候变化对人类健康的迫在眉睫的威胁，城市规划者和设计师更加关注户外热舒适（OTC）研究。从历史上看，室内热舒适性研究假设稳态条件，集中在热中性的概念以确定最佳环境参数。此类研究的重点是调查非稳态瞬态环境条件如何影响舒适度。最近的研究强调了积极的麻醉在为 OTC 评估提供富有成效的框架方面的有用性。在本文中，我们首先阐明文献中与热舒适相关的术语、尺度和模型相关的概念。然后，我们提出了四个我们认为对热瞬态感觉研究很重要的研究问题。为了回答这些问题，我们介绍了当前研究的状态和该领域的差距，并提供了可以推进动态 OTC 知识的方向。
