常量、变量间的相等与不等关系问题是数学问题的一类核心问题,同时也展现了非常丰富的内涵.从数学美的角度看,相等展现了一种均衡与有序之美,不等展现了一种混沌与奇异之美.在具体情境中,往往需要从丰富的相等与不等条件关系中去挖掘丰富的相等与不等的结果关系,这也在一定程度上凸显了问题的广度与难度所在.本文通过对三道竞赛题的求解,探究"由等到不等、 The problems of equality and unequal relation between constant and variable are a kind of core issue of mathematics problem, meanwhile they also show a very rich connotation.From the perspective of mathematical aesthetics, they show equal and orderly beauty equally, ranging from A kind of chaos and singular beauty.Under specific circumstances, it is often necessary to tap the rich relationship between equal and unequal conditions, which also highlights the breadth and difficulty of the problem to a certain extent Through the solution to the three contestants’ questions,
