标题： Abstraction, Explanation, and Effective Field Theories

摘要： 有效场论（EFTs）被物理学家广泛认为是具有解释力的，并且是用于在不同尺度上建模各种现象的适当框架。 同时，它们被认为是近似的、有限的和仅仅是有效的，因此，研究它们可以为解决诸如理想化、抽象以及解释中表征的真实性等哲学问题提供一种途径。 本文将EFTs视为更基本理论的\textit{摘要}模型，这些模型保留了对于给定解释对象来说所有且仅有的相关方面。 我将抽象描述为一个过程，该过程可以从一个独立具有解释力的基本理论自上而下地保留解释。 因此，本文旨在说明像EFTs这样的抽象模型如何作为更基本模型的解释替代物发挥作用，这通常被认为是没有问题的。 显示英文摘要

摘要： Effective field theories (EFTs) are widely considered by physicists to be explanatory and to be the appropriate frameworks for modelling various phenomena at different scales. At the same time, they are known to be approximate, restricted, and merely effective, and thus, examining them can provide a means of getting traction on philosophical issues such as idealisation, abstraction, and the veridicality of representations in explanation. This paper casts EFTs as \textit{abstract} models of a more fundamental theory that retain all and only the relevant aspects for a given explanandum. I describe abstraction as a process that can preserve explanation top-down from an independently explanatory fundamental theory to an effective theory. Thus the paper aims to show how abstract models, like EFTs, can function as explanatory stand-ins for more fundamental models, something often taken to be unproblematic.
