摘要
本文研究了Ｄｉｒｉｃｈｌｅｔ和Ｎｅｕｍａｎｎ静电边界问题下格林函数的对称性，给出了Ｎｅｕｍａｎｎ问题对称性格林函数的制作方法，并以同心球壳之间空间格林函数的制作为例说明了这一方法的应用。
In this paper,the authors study the symmetry of Green's Functions satisfying the Dirichlet boundary condition and the Neumann's in electrostatic problems and present the method of constructing the symmetric Green's Function on the Neumann problems. As an example,the Green's functions are taken into consideration between two concentric spheres of radii a and b (a<b).
