In this paper, I propose a general framework for understanding renormalization by drawing on the distinction between effective and continuum Quantum Field Theories (QFTs), and offer a comprehensive account of perturbative renormalization on this basis. My central claim is that the effective approach to renormalization provides a more physically perspicuous, conceptually coherent and widely applicable framework to construct perturbative QFTs than the continuum approach. I also show how a careful comparison between the two approaches: (i) helps to dispel the mystery surrounding the success of the renormalization procedure; (ii) clarifies the various notions of renormalizability; and (iii) gives reasons to temper Butterfield and Bouatta’s claim that some continuum QFTs are ripe for metaphysical inquiry (Butterfield and Bouatta, 2014).

重新规范化审查

在本文中，我提出了一个通过有效和连续量子场理论（QFT）之间的区别来理解重归一化的通用框架，并在此基础上全面介绍了扰动重归一化。我的主要主张是，与连续方法相比，有效的重新规范化方法为构造扰动QFT提供了更直观的，概念上一致的和广泛适用的框架来构造扰动QFT。我还展示了两种方法之间的仔细比较：（i）有助于消除围绕重新规范化过程成功的神秘感；（ii）阐明可重归一性的各种概念；（iii）给出了缓和Butterfield和Bouatta的主张的理由，即某些连续统QFT对于形而上学的探究已经成熟（Butterfield和Bouatta，2014年）。
