数学中的转化与化归思想是指将陌生问题向已知、熟悉的问题转化,通过一般与特殊的转化、等与不等的转化、变量与常量的转化、数与形的转化、正与反的转化、抽象与具体的转化,使问题化难为易.特殊化常表现为范围的收缩或限制,即从较大范围的问题向较小范围的问题过渡,或从某类问题向其子类某问题的过渡,从而使问题迎刃而解.
The conversion of mathematics and the return of thought refers to the conversion of strange problems to known and familiar problems through transformations of general and special, unequal conversion, transformation of variables and constants, conversion of numbers and forms, Anti-transformation, abstraction and concrete transformation, so that the problem is difficult for the easy.Particularly manifested as the specialization of the scope of the contraction or limitation, that is, from a larger range of problems to a smaller range of transition, or from a type of problem to their son Class transition of a problem, so that the problem be solved.
