在现代数学研究的公理化方法、模型方法结构方法等各种方法中,化归是一种基本的方法,由于它的思想深刻、方法多样、具有广泛的普适性,因此成为方法论中重要的方法原则之一.本文拟论述化归原則及其与规范化的关系,并对它的结构特征、思想方法和分类层次进行探讨. 一、化归原则与规范化化归方法,是通过数学内部的联系和矛盾 In various methods such as the axiomatic method of modern mathematics research, model method structure and method, transformation is a basic method. Because of its profound thoughts, diverse methods, and wide universality, it has become an important methodological method. One of the principles of the method. This article is intended to discuss the principle of transformation and its relationship with the standardization, and to discuss its structural features, methods of thinking and classification levels. First, the principle of return and normalization, is through the internal relations of mathematics And contradictions
