摘　　要：同构是比较两个集合最有效的工具。在同构意义下,抽象地看两个集合的性质相同,同构映射一直备受专家和学者的关注。本文主要从同构映射的定义出发,探讨了同构视角下高中指数函数与对数函数,等差数列与等比数列的关系,并深入分析了这一视角在数学教学和实际应用中的价值,揭示了通过同构理解不同数学概念之间深层次的联系,为高中数学教育提供了新的方法论。Homomorphism is the most effective tool for comparing two sets. In the sense of homomorphism, the properties of two sets are abstractly considered to be the same, and homomorphism mappings have always been of great interest to experts and scholars. This article mainly starts from the definition of homomorphism mapping and explores the relationships between exponential functions and logarithmic functions, arithmetic sequences and geometric sequences from the perspective of homomorphism. It also analyzes the value of this perspective in mathematics teaching and practical applications, revealing the deep connections between different mathematical concepts through homomorphism and providing a new methodology for senior high school mathematics education.
