本文用有限的二重傅里叶变换解波动方程,热传导方程,拉普拉斯方程以及泊松方程的非齐次边值问题。
In this paper, the finite double Fourier transforms were applied to solve the nonhomogeneous boundary value problems of the wave, heat conduction, Laplace and Poisson equations.
通过引入静电场的标量位函数,将电场强度的矢量泊松方程转化为位势的椭圆型偏微分方程的诺依曼边值问题。
And the problem is converted to the typical Neumann boundary value problem for the elliptic equations by inducing the scalar potential function.
