某些特殊问题,直接难于寻求解答的方法,于是,变更命题,提出关于这类特殊问题的一般性命题,使原命题强化,反而易于找出解答的关键。这种通过对一般命题的研究而解决特殊问题的方法,我们称为强化命题法。对于某些特殊问题或用常法比较繁难的数学题,倘若我们用强化命题法来解,则往往可打破常规,巧辟捷径,从而使问题变繁为简、化难为易、迎刃而解。请看下面三例。
Some special problems are directly difficult to find solutions. Therefore, changing the propositions and proposing general propositions on such special issues make the original propositions intensify, but it is easier to find the key to the solution. This method of solving special problems through the study of general propositions is called reinforcement proposition. For certain special questions or math problems that are difficult to solve with the common law, if we use the method of strengthening propositions to solve, we can often break the conventions and create shortcuts, so that the problems can be simplified, simplified, and easily solved. Please see the following three examples.
