摘　　要：以经典力学中拉格朗日力学和哈密顿力学的结构分析为例,文章通过二者数学上同构的建立,揭示数学结构是物理学结构的必要前提和基础。运用范畴结构主义的本体论特征,尝试突破结构实在论的困境,为结构实在论做出辩护。By exemplifying analyses of the structures of Lagrangian mechanics and Hamiltonian mechanics in classical mechanics,the relations between the structure of physics and the structure of mathematics are shown in essence by finding their isomorphism in mathematics. On this basis,it is further clarified that mathematical isomorphism is the necessary premise and basis of physics structure;moreover,according to the ontological characteristics of categorical structuralism,this paper breaks through the predicament of structural realism and makes a defense for it.
