1、Renormalization is a mathematical technique used in quantum field theory to remove infinities and make sense of calculations.

重整化是量子场论中用于消除无穷大并使计算有意义的数学技术。

2、In physics, renormalization refers to the process of adjusting certain parameters in a theory to account for the effects of high-energy phenomena.

在物理学中，重整化是指调整理论中的某些参数以考虑高能现象的影响的过程。
