均匀导体棒所产生的电场,其求解方法中可以包含静电场中定性分析的众多方法,如:模型法、形象思维法、极端思维法、等效法、类比法、微元法、对称法、独立作用原理与叠加原理。其蕴含的多种思维能力要求,如:直觉与逻辑、宏观与微观、形象与抽象、独立作用原理与叠加原理、整体与部分、甚至定性与定量都蕴藏其中。

The solution of the electric field generated by a uniform conductor bar can include many methods of qualitative analysis in the electrostatic field, such as model method, image thinking method, extreme thinking method, equivalent method, analogy method, micro-element method, symmetry method, independent Principle of action and superposition principle. The implication of a variety of thinking skills, such as: intuition and logic, macroscopical and micro, image and abstraction, the principle of independent action and superposition principle, the whole and part, even qualitative and quantitative are hidden.
