For example, an electron theory may begin by postulating an electron with an initial mass and charge. In quantum field theory a cloud of virtual particles, such as photons, positrons, and others surrounds and interacts with the initial electron. Accounting for the interactions of the surrounding particles (e.g. collisions at different energies) shows that the electron-system behaves as if it had a different mass and charge than initially postulated. Renormalization, in this example, mathematically replaces the initially postulated mass and charge of an electron with the experimentally observed mass and charge. Mathematics and experiments prove that positrons and more massive particles like protons, exhibit precisely the same observed charge as the electron - even in the presence of much stronger interactions and more intense clouds of virtual particles.

例如，电子理论可以从假定电子具有初始质量和电荷开始。在量子场论中，一个由诸如光子、正电子等虚粒子组成的云团围绕着初始电子并与之相互作用。考虑到周围粒子的相互作用(例如:。不同能量的碰撞)表明电子-系统的行为好像它有一个不同的质量和电荷比最初的假设。重整化，在这个例子中，数学上用实验观察到的质量和电荷代替了最初假设的电子的质量和电荷。数学和实验证明，正电子和质子等质量更大的粒子，即使存在更强烈的相互作用和更密集的虚粒子云，其电荷也与电子完全相同。

Renormalization specifies relationships between parameters in the theory when parameters describing large distance scales differ from parameters describing small distance scales. In high-energy particle accelerators like the CERN Large Hadron Collider the concept named pileup occurs when undesirable proton-proton collisions interact with data collection for simultaneous, nearby desirable measurements. Physically, the pileup of contributions from an infinity of scales involved in a problem may then result in further infinities. When describing space-time as a continuum, certain statistical and quantum mechanical constructions are not well-defined. To define them, or make them unambiguous, a continuum limit must carefully remove "construction scaffolding" of lattices at various scales. Renormalization procedures are based on the requirement that certain physical quantities (such as the mass and charge of an electron) equal observed (experimental) values. That is, the experimental value of the physical quantity yields practical applications, but due to their empirical nature the observed measurement represents areas of quantum field theory that require deeper derivation from theoretical bases.

当描述大距离尺度的参数不同于描述小距离尺度的参数时，重整化指定了理论中参数之间的关系。在像欧洲核子研究中心这样的高能粒子加速器中，当质子-质子的不期望碰撞与数据收集相互作用，以便同时进行附近期望的测量时，就会出现连续大型强子对撞机的概念。从物理上来说，一个问题所涉及的无限量级的贡献累积起来可能会导致进一步的无限量。当把时空描述为一个连续统时，某些统计的和量子力学的结构没有得到很好的定义。为了定义它们，或者使它们毫不含糊，连续统的限制必须小心地移除不同尺度的晶格的“结构脚手架”。重整化过程的基础是要求某些物理量(如电子的质量和电荷)等于观察到的(实验)值。也就是说，物理量的实验值产生实际应用，但由于它们的经验性质，所观察到的测量代表了量子场论的领域，需要从理论基础进行更深入的推导。

Renormalization was first developed in quantum electrodynamics (QED) to make sense of infinite integrals in perturbation theory. Initially viewed as a suspect provisional procedure even by some of its originators, renormalization eventually was embraced as an important and self-consistent actual mechanism of scale physics in several fields of physics and mathematics.
