本文所指的参量,是指在解题过程中,充当某种媒介作用的常数或者变数.参量的作用在于,能够使定性的问题变成定量的问题,使多变元的问题演变成更少变元的问题,从而使问题的解决得以明晰或者简化.在解决某些问题的过程中,参量常常起着重要的转化与沟通的作用,这种作用在解题中有时是不可或缺的.一、增强参量意识参量在解题中的作用是广泛的.对于某些数量关系似乎不确定,或者所牵涉的变元较多的问题,其解题过程往往需要借助添设参量的
In this paper, the parameter refers to the constant or variable acting as a medium in the process of problem solving.The role of the parameter is to make the qualitative problem a quantitative problem and the multi-argument problem to evolve into fewer Argument, so that the problem can be solved clearly or simplified.In the process of solving some problems, the parameters often play an important role in transformation and communication, and this role is sometimes indispensable in solving problems. First, to enhance the role of parametric parameters in solving problems is extensive.For some quantitative relations seem uncertain, or the variables involved in more problems, the process of solving problems often need to add parameters
