摘要
介绍求解非平行板电容器电容和电场的两种计算方法,一种是从平行板电容器的概念入手的求解方法,另一种是利用电场能量和电容器的能量公式,解出非平行板电容器的电容和电场分布.通过对上述两种方法的讨论,指出第二种方法,严格、简捷易懂,图像清晰,且颇具新意.
The methods of two kinds for calculating the capacitance and electric field between an unparallelplate capacitor are presented： the one is by using the concept of parallel plate capacitor and the formula of capacitors connected in parallel, another is by using the electric energy formulae of an electric field and a capacitor with charges. It is found in comparison with the two methods that the second method is stricter, simpler, clearer and more innovative.
