摘　　要：在关于科学实在论的争论中,有两个最引人注目的论点是“无奇迹论证”和“悲观元归纳”,这两种理论背道而驰,最终分别指向实在论和反实在论。为了打破这一僵局,沃勒尔引入了结构实在论,沃勒尔的结构实在论是认识论版本的结构实在论,在沃拉尔的基础上,雷迪曼引入了本体论版本的结构实在论,这两个版本都是依据物理学的发展提出的。文章基于规范场论的对称群讨论结构实在论,并指出量子场论的幺正不等价表示和结构实在论的辩护方法。In the debate on scientific realism,there are two most striking arguments:“no miracle argument”and“pessimistic meta-induction”,which run counter to each other and eventually point to realism and anti-realism.In order to break this deadlock,Worrall introduced structural realism,while Worrall’s structural realism is an epistemological version of structural realism.On the basis of Worrall’s realism,Ladyman introduced an ontological version of structural realism,both of which were put forward according to the development of physics.This paper discusses structural realism based on the symmetry group of gauge field theory,and points out the unitary inequivalent representation of quantum field theory and the defense method of structural realism.
