根据位场在频率域的泊松方程和积分表达式,证明了三维位场的频谱在座标轴上与相应二维场频谱成正比的等价定理,并以几种模型作为定理的例证。
According to the Poisson equation and the integral expression of the field in the frequency domain, we prove the equivalent theorem that the frequency spectrum of the three-dimensional field is proportional to the corresponding two-dimensional field spectrum in the coordinate axis. Several models are taken as examples.
