用静电场高斯定理求电场强度和磁场环路定律求磁场强度的讨论

Discussion on electric-field intensity with electrostatic field Gauss theorem and magnetic field intensity with magnetic field loop law

本文要讨论两个问题 :1 运用电场高斯定律求场强的条件和高斯面选取的方法 ;2 运用磁场环路定律求磁场H的条件和环路选取的方法 。

Two problems are analyzed with examples in this paper. First, the condition for electric-field intensity calculation with Gauss theorem and selection method for Gauss section; Second, condition for magnetic field with magnetic field loop law and selection method for loop.
