张茂祥同志提出的是加权余量法应用中的一个重要而有兴趣的问题。 文献[1]曾就类似的平面调和方程的求解进行过讨论,下面扼要介绍该文的主要结论,对此问题的讨论是有益的。该文指出,对于平面单联通区域中的单值调和函数问题,当用下述调和多项式进行逼近时, Comrade Zhang Maoxiang proposed an important and interesting issue in the application of the weighted residual method. The literature [1] discussed the solution of a similar planar harmonic equation. The following is a summary of the main conclusions of this paper. The discussion of this issue is beneficial. The article points out that for the problem of the single-valued harmonic function in the planar single-pass region, when the approximation is performed with the following harmonic polynomial,
