量子场论总纲领下诸竞争子纲领的互动与发展——从科学哲学和辩证法的眼光来看

The Interaction and Development of Each Sub-programmes under the Several Quantum Field Theory

"定域算符场"理论是量子场论的标准形式,它重视动力学机制,并采用微扰方法进行重整化。与此对立的观点主要有:公理化场论(对点模型实施模糊化,即采用涂抹[smearing]方法)/S散射矩阵理论(关注形式特征)/流代数(关注基本对称性)。这几个非正统纲领的本意,都是只注重形式因子,不考虑动力学机制的细节,拒斥正统的"定域算符"量子场论。然而,相互竞争的研究纲领争斗的结果是最终各派观点走向融合。它们实际上促进了动力学机制的细致研究,并为在更高的层次上回到量子场论框架铺平了道路。文中分析了各派观点中所包含的辩证内涵。

'Localized operator field' theory is the standard form of Quantum Field Theory,which emphasizes on dynamic mechanism and uses perturbation to make renormalization.The opposed viewpoints are axiomatic field theory(to fuzzify point model,i.e.to use smearing method),S scattering matrix(focusing on formal character),current algebra(focusing on fundamental symmetry).These heterodox programme basically focus on formal factor without thinking on the detail of dynamic mechanism,refusing orthodox 'Localized operator' Quantum Field Theory.However,the result of competing programmes combating is the syncretization of viewpoints of each school,which actually promote the study of dynamic mechanism in detail and pave the path for returning to Quantum Field Theory framework in more advanced level.This paper analyzes the dialectical implication of the viewpoints of each school.
