摘　　要：根据解析函数的性质,通过反双曲正弦函数及边界条件,导出了共焦双曲柱面间的电场和单位长度的电容,并对一些特例作了讨论.By using the properties of the analytic function,the electric field and the capacitance per unit length between the confocal hyperbolic cylinders are derived by the inverse hyperbolic sine function and the boundary condition,and some special conductor configurations are also discussed.
