摘要
文中给出格林函数基本解的一般式，从而使计算中参考．人的选择具有任意性，为分析和比较计算结果带来方便，使直接积分法的应用更为灵活。另外，对静电独立系统，当参考点选在匹配点上时，将出现亚定方程问题。文章在此将电荷守恒定律作为必要条件引入，使得方程具有唯一确定的解。
The general form of the basic solution of the Green's function given in this paper enables one to select the reference point arbitarily, thus making the direct integrating method more adaptab1e to comparing and analysing the results- For independent static systems, when the reference is located at the matching point a substable equation will appear. The conservation law of charge is taken here as a sine qua non so that the equation can have the unique solution.
