ABSTRACT Proponents of present-day Science and Technology Studies (STS) tend to disregard classical phenomenological research by considering it incompatible with the performative turn in STS. The paper counters this tendency by exploring the case of so-called epistemic things and how this particular notion can be used to extend Heideggerian phenomenology. Heidegger is well-known for drawing a distinction between things that are ready-to-hand (i.e. handy) and things that are present-at-hand (i.e. unhandy). Although these two categories delineate many everyday objects, there are also instances where things cannot simply be considered as involving either handiness or unhandiness. One such example is that of drones used for detecting leakages in heat pipes. In being epistemic, these drones form part of a technical assemblage that can be used for uncovering and exploring suspected leakages – or knowledge objects – thus rendering the hidden visible.

使隐藏可见：方便的不便和泄漏检测无人机的感觉

摘要 现代科学技术研究 (STS) 的支持者倾向于忽视经典现象学研究，认为经典现象学研究与 STS 的表演转向不相容。本文通过探索所谓的认知事物的情况以及如何使用这一特定概念来扩展海德格尔的现象学来对抗这种趋势。海德格尔以区分现成的（即方便的）事物和现成的（即不方便的）事物而闻名。尽管这两个类别描绘了许多日常用品，但也有一些实例不能简单地将事物视为涉及方便或不方便。一个这样的例子是用于检测热管泄漏的无人机。在认知上，
