中学物理中有许多问题都必须借助数学来解决,而解析法往往只注意到状态而忽视了过程,而对于连续变化问题必须考虑物理实际过程的变化。由于函数图像直观、明了,同时又能反映物理状态连续变化的特点,对研究物理过程有所帮助。现就几个典型图像作一探讨。 Many problems in middle school physics must be solved by means of mathematics. Analytic methods often only pay attention to the state and ignore the process. However, for the problem of continuous change, the actual physical process must be considered. Because the function image is intuitive and clear, and at the same time it can reflect the continuous change of the physical state, it helps to study the physical process. Let us discuss a few typical images.
