在媒介物质性越来越引起传播学研究重视的情况下，媒介物的中介化问题还未得到 充分探讨。本文将“身体-媒介物”共生体作为研究起点，通过梳理拉图尔的技术哲学 和唐·伊德的后现象学中关于“人与技术物的中介化关系”的思想，揭示：具身于身体 的媒介物具有差异性的中介化意图，显现出“上手”且“透明”的共同意向；它们在与 身体的融合与交互中总是转变人的行动且调节人的体验；媒介物中介了人与物、物与物 以及人与人之间的信息传递与沟通交往，打造出日常生活的物质性“联盟”。这一联盟 易形成“媒介化”社会中特定科技、文化、商业与意识形态的垄断，将人订造、促逼且 物化，从而产生新的人与技术的冲突与较量。

With the increasing importance of media’s materiality in the study of communication, the problem of mediation has not been fully explored. This article takes the symbiosis of “body-mediator” as the starting point of research, through combing the philosophy of technology from Bruno Latour and post-phenomenology thoughts on “the mediating relationship between human and artifacts” from Don Ihde. It reveals that the mediators embodied on human have different mediating intentions, showing the same intentions of “readiness-to-hand” and “transparence”; they always transform human’s actions and regulate their experience in the integration and interaction with the bodies; the mediators create a material “association” of daily life by mediating the transmission and communication of information between human and things, things and things, and human and human. This association is easy to form a monopoly of specifc technology, culture, commerce and ideology in a “mediatized” society, which en?ames, forces, and materializes human, thereby creating new con?icts between human and technologies.
