摘要
给出具有两个实自变数的未知函数的线性偏微分方程(组)调和函数解存在的一个充分条件,及在此条件下方程(组)调和函数解的简化求法.
To the double independent real variable linear partial differential equation (system of equations), a sufficient condition for the existence of the harmonic function solution is supplied, and a method of how to obtain this harmonic solution under this condition is given.
