The Elementary Function Formations of the Electric Field and the Capacitance between Two Semi—Cylindrical Surfaces

本文应用求解析函数的方法求得由两个半圆柱面组成的电容器的电容为一简单的初等函数C=(2ε)/πlnctg(θ_0)/2,本文还讨论两个半椭圆柱面间电场和电容。

we find that its capacitance C=(2ε)/πlnctg(θ_0)/2by using the method of analytic function, In ad- dition the electric field between semi-elliptical surfaces and the capacitance of capacitor con- structed of two semi-elliptical surfaces will be further discussed.
