摘　　要：根据椭圆和双曲线几何知识,在直角坐标系下,选合适的函数,运用拉普拉斯方程以及磁标势梯度公式来计算出共焦椭圆柱形电缆的磁感应强度.According to the geometric knowledge of ellipse and hyperbola,the magnetic induction intensity of the confocal elliptic cylindrical cable is calculated by using the Laplace equation and the magnetic scalar potential gradient formula in the rectangular coordinate system and the appropriate function.

关 键 词：共焦椭圆 磁标势 磁场强度 磁感应强度
