物理图像可以形象直观地揭示物理规律及物理量之间的相互依赖关系,在高考大纲的能力要求中,就有“必要时能运用几何图形、函数图像进行表达、分析”的要求,具体表现在对物理规律、状态和过程在理解的基础上用合适的图像、图线表示出来,会用图像、图线来处理物理问题.近年来,图 The physical image can reveal the physical laws and the interdependence between the physical quantities vividly. Among the competency requirements of the college entrance examination syllabus, there is the requirement that “geometric figures and function images can be used when necessary to express and analyze”. Specifically, Physical laws, states and processes are represented on the basis of understanding with appropriate images and lines, and are used to deal with physical problems with images and lines. In recent years,
