本文给出了量子场论中算符乘积展开式的模型无关的非微扰证明。作为输入，最近提出的相空间条件，允许一个精确的描述点场结构。在乘积展开式的基础上，定义并分析了Zimmermann意义下的正规乘积。
The paper presents a model-independent, nonperturbative proof of operator product expansions in quantum field theory. As an input, a recently proposed phase space condition is used that allows a precise description of point field structures. Based on the product expansions, we also define and analyze normal products (in the sense of Zimmermann).
