类比,是根据两个对象有某些相同或类似的属性,并且其中一个对象还有某些另外的属性作为前提,提出另一个对象也有这些相同或类似属性的一种思想方法.这种思想方法的可贵之处在于,人类的生产和生活中有很大一部分依靠着这个思想来发展,它在数学领域也占据了重要的一席之地.美国数学家波利亚在《数学与合情推理》一书中提出:“类比是一个伟大的引路人.…没有这些思路(普遍化、特殊化和类比),特别是没有类 Analogy is based on the two objects have some of the same or similar attributes, and one of the objects there are some other attributes as a prerequisite for another object also has these same or similar attributes of a way of thinking. This way of thinking Valuable point is that a large part of human production and life rely on this idea to develop, it also occupies an important place in the field of mathematics .American mathematician Polya in ”Mathematical reasoning and reasoning,“ a book Put forward: ”analogy is a great guide. ... Without these ideas (generalization, specialization and analogy), especially no class
