有些数学竞赛问题 ,通过引入或挖掘辅助参数 ,使得这些参数在解题中起到联系分散条件 ,显示隐含因素 ,转化命题结构 ,简化解题过程 ,促成条件与结论的有机结合 ,进而对解题起到“催化”和“桥梁”的作用 .下面从三个方面浅析参数在解数学竞赛题中的辅助作用 .1　参数在解题中的 Some mathematic contest problems, through the introduction or mining of auxiliary parameters, make these parameters in the solution of the problem as a decentralized condition, show hidden factors, transform the proposition structure, simplify the problem-solving process, and promote the organic combination of conditions and conclusions, and then solve the solution The title plays the role of “catalysis” and “bridge”. The following is an analysis of the auxiliary role of parameters in solving mathematics competition questions from three aspects. 1 The parameters in the problem solving
