将待解决或难解决的问题通过某种转化过程,化归为一类已经解决或比较容易解决的问题的一种思维模式就是转化思想,转化常分为等价转化与不等价转化.一、等价转化等价转化要求转化过程中前因后果应是充分必要的,这样的转化能保证转化的结果即为原问题所需的结果.
A kind of thinking mode that converts problems to be solved or difficult to solve into a class of solved or relatively easy to solve problems through a certain transformation process is to transform ideas, which are often divided into equivalent transformation and inequivalent conversion. Equivalent transformation and equivalent transformation require that the antecedent and consequence in the transformation process should be sufficient and necessary. Such transformation can ensure that the result of transformation is the required result of the original problem.
