摘要: 由椭圆和双曲线的性质得出有限长均匀带电直线的等势面为椭球面.采用椭球面坐标系,利用高斯定理由直接积分法求解了有限长均匀带电直线的电场和电势分布,并进行了必要的讨论.

关键词: 电场强度, 椭球面坐标系, 高斯定理

Abstract: Based on the property of ellipse and hyperbola, we find that the equipotential surface of a finite line with even charge is ellipsoid. Using ellipsoidal coordinates, we calculate the electric field and potential with Gauss theorem by direct integral, and make some essential discussions.

Key words: electric field intensity, ellipsoidal coordinates, Gauss theorem
