在《建立解题方程的三条基本依据及其关系》(本刊1999年第11期)一文中,笔者明确指出:构成解题方程的基本形式只有公式方程、等量方程和比例方程三种.但是,各种物理计算题的解题方程类型,却这不止以上三种.它们可能是这三种基本形式中的某一种;也可能是由这三种基本形式联立构成的解题方程组.然而,无论这三种基本形式如何组合,归纳起来,物理计算题的所有解题方程(组)也只能是有限的两类十种类型,即三类方程和七类方程组.下面用去年四省市的中考
In the article “Establishing the Three Bases of Problem Solving Equations and Their Relationships” (No. 11 of 1999), the author clearly pointed out that the basic forms of solving problem equations are only equation equations, equal equations and proportional equations. However, there are more than three types of problem solving equations for various physical computing problems. They may be one of these three basic forms; or they may be the solving equations formed by the three basic forms. Group. However, no matter how these three basic forms are combined, to sum up, all solving problem equations (groups) of physical computing problems can only be limited to two types of ten types, ie, three types of equations and seven types of equations.
