图像是“数”与“形”相结合的产物,是“具体”与“抽象”相结合的综合体现。作为表示物理规律方法之一的物理图像,能够把物理公式中各物理量之间的相互依赖关系在直角坐标系中清晰地展示出来,可明快地解决实际的物理问题。它既能直观、形象、概括地反映某两个相关物理量之间的关系,也能将一些用抽象数学解析式或文字无法表达或表达不清的物理现象、物理过程、物理状态、物理规律包含其中;它既是丰富的物理信息的载体,又是形象思维和抽象思维相互联系的纽带;它既是广泛应用于科学实验中分析实验数据的方法之一,也是理论研究时常用的手段之一。物理图像常常能弥补纯数学图像的不足(如果从纯数学
The image is the product of the combination of “number” and “form”, and it is a comprehensive embodiment of the combination of “concrete” and “abstract”. As a physical image representing one of the methods of physical laws, it is possible to clearly display the interdependence of each physical quantity in the physical formulae in a rectangular coordinate system, which can solve practical physical problems clearly. It can not only intuitively, visually, and generally reflect the relationship between two related physical quantities, but also include some physical phenomena, physical processes, physical states, and physical laws that are not expressible or expressible in abstract mathematics. Among them, it is not only the carrier of abundant physical information, but also the link between image thinking and abstract thinking. It is not only one of the methods widely used in the analysis of experimental data in scientific experiments, but also one of the commonly used methods in theoretical research. Physical images can often make up for the insufficiency of purely mathematical images (if pure mathematics
