从静电学的互易定理看调和函数的性质

Understanding the properties of harmonic functions from the reciprocal theorem of electrostatics

基于静电学的互易定理证明了调和函数的平均值定理、格林函数的互易定理、调和函数与其格林函数的联系.

Based on the reciprocal theorem of electrostatics,the average theorem of harmonic functions, the reciprocity of associated Green＇s functions, and the relation between harmonic functions and their Green＇s functions are proved.
