用长旋转椭球坐标表示有限长带电直线的空间电势

SPACE POTENTIAL DISTRIBUTION OF A FINITE LENGTH CHARGED CONDUCTIVE LINE IN THE LONG ROTATING ELLIPSOID COORDINATES

利用长旋转椭球坐标直接证明有限长带电直线电荷在空间中产生的等势面是共焦长旋转椭球面.

In the long rotating ellipsoid coordinates,it can be directly demonstrated that the equipotential surface in the space generated by a finite length charged conductive line is conform with the prolate ellipsoid surface.
