在高中物理实验中,各个物理量的关系错综复杂,有些物理量之间存在着线性关系,有些物理量之间存在着非线性关系.图像法是解决上述问题的一个比较直观的途径,但图像法在解题过程中遇到非线性变化关系时,就只能定性研究而难以定量计算.实际上在处理这样的一些非线性数据或问题时,我们可以采用转化的思想,可以将这种非线性关系转化为线性关系,将曲线变化规律转化为直线变化规律,这样有助于分析问题和定量求解. In high school physics experiment, the relationship of each physical quantity is complicated, some of them have a linear relationship, and some of them have nonlinear relationship.Image method is a more direct way to solve the above problems, In the process of encountering non-linear changes in the relationship, it can only qualitative research and difficult to quantitative calculation.In fact, in dealing with such a number of non-linear data or problems, we can use the idea of ​​transformation, this non-linear relationship can be transformed into Linear relationship, the curve changes the law into a straight line changes, so help to analyze the problem and quantitative solution.
