高斯定理的理解与应用

文章论述了高斯定理源于库仑定律，依赖于场强叠加原理，场强通量与场线通量均遵从高斯定理；高斯面上的场强是其内外所考虑的电荷产生的合场强；构建体系高斯面，局部高斯面求解场强问题。

Comprehension and Application of Gauss Theorem

This paper argues that Gauss Theorem stems from Coulomb's Law,relies on the principle of superposition of field intensity.Furthermore,the flux of electric field intensity and that of electric line both follow Gauss Theorem.It is also argued that electric field intensity on the Gaussian surface is the combined electric field intensity produced by the electric charge considered inside and outside,and that the system Gaussian surface and the portion Gaussian surface are proposed to establish to solve the problem of electric field intensity.
