文章以偏心圆柱电容为例，通过构造一个满足边界条件的势函数，进而得到相应的静电场和电场能量密度。
With an example of eccentric column capacity , a potential function that satisfies the boundary conditions is formed to obtain corresponding electromagnetic field and its energy density .

与一般方法不同，本文利用电通量概念及电场叠加原理，推导出电场能量密度的普遍表达式。方法简明。
This method is different from usual method , we use the concept of electric flux and principle of superposition for the electric field .
