After an analysis of the enlightenment and guidance of correspondence principle on the physics thought and methodology in the course of proposing quantum theory and the establishment of quantum mechanics, this article discusses the ideological connotation and puts forward the belief that correspondence principle reflects the fact that when substance can be neglected within certain limits, the physics model with universality is tending to become similar to that with particularity.

分析了在量子论的提出和量子力学的建立过程中，对应原理在物理思想和方法论上的启发和指导作用；讨论了对应原理的思想内涵，认为对应原理反映了当物质的某些属性在极限情况下可以忽略时，普遍性的物理模型趋同于特殊性的物理模型，普遍性的理论可以过渡到特殊性的理论，在结论上趋同于特殊性的理论。
