摘要
描述粒子物理学的核心语言是可重整化的量子场论。重整化最初是应对量子场论中数学计算无穷大问题的有效策略,是解决理论物理学中“突现”问题的有力手段。本文从重整化操作在量子场论中产生的影响出发,回顾了有效场论思想产生的历史,叙述了重整化方法所引起的哲学争论,旨在对还原论和反还原论在解释量子场论中涉及的“还原”、“突现”、“层次性”等问题予以方法论考察,最后从语境的视角对重整化方法进行诠释,指出对基础理论及理论间关系的探讨是具有境遇性的。
The renormalizable quantum field theories are the main theories to describe the particle phenomena in the high-energy physics. It is only a effective method to deal with the emergence in physics. In this papar,we start from the effect of the renormalization conception,recover the history of the effective field theory conception,introduce the methodological aspects such as "reduction", "emergence","category" and so on. At last, from the contextual stand, we give a brand new checkout and result in our discussion is context-dependent one.
